Post and Beyond Lithium-Ion Materials and Cells for Electrochemical Energy Storage
A Google TechTalk, 2/9/18, presented by Andreas Hintennach ABSTRACT: Ever since the development of lithium-ion batteries the spirit of invention has mainly lead to an evolution of existing materials. With the focus on olivine and Nickel- and cobalt based materials the energy densities, power densities and ageing mechanisms could be investigated over the years and support the understanding of the underlying mechanisms of electrochemical energy storage and conversion. With increasing numbers of cells being used in the world the need of a post Lithium-Ion technology emerges due to a limited availability of highly pristine nickel and cobalt and increasing need for recycling, environmental protection and overall energy efficiency. Nevertheless there is still an ongoing and very promising approach for e. g. novel stoichiometries of NMC materials, olivine materials, and nickel-rich materials with can significantly increase the energy density. But due to some limitation in the field of raw materials availability, accessibility, and sustainability, low-cobalt or cobalt-free materials are of very high interest, too. For example LMR (LNMO) can be an ideal candidate. Due to the very high reactivity and potential (i. e. 4.5 V) these materials require highly stable electrolytes. Finally, lithium-sulphur can lead to a highly recyclable, environmentally friendly system. Having a silicon-based anode (greater than 85 % Si) included both volumetric and gravimetric energy density can mean an interesting alternative to metal-oxide based materials. With the increased energy density, safety becomes a more and more important aspect in thermodynamic and kinetic investigations of these materials. This aspect can lead to the development of non-flammable electrolytes or solid state cells. Solid state cells are a very different but highly promising approach. Having a solid-solid interphase between electroactive materials and electrolyte the chemicals mechanisms significantly change to solid state chemistry rather than solid-organic interphases chemistry. All types of novel chemistries exhibit very different chemical mechanisms which require specific synthetically work, e. g. with the support of numerical simulation, for electrolytes, additives, binders, carbon materials, and even the surfaces of the electro-active materials itself. Understanding these mechanisms is essential to further improve the life-time, efficiency, and hence, the sustainability of any kind of energy storage and conversion, but batteries in particular.

DIY 55$ 24AH Lithium-Ion 18650 E-Bike battery 100+ Mile Range: complete build
Previous E-bike Video: https://www.youtube.com/watch?v=oYXreeuv3Jw in this video i build the second 24v 24ah lithium battery block for my 48v 24ah bicycle battery. i built this pack from low quality 18650 cells. each 6 cell pack cost 4.99$ so thats only about 85 cents per cell. even if they are low quality that is wonderfully useful. in this video when i say a cell is "unstable" i mean it is more likely to short out when it's voltage is dropped due to metal buildup on the plates. the main differances between good quality cells and poor quality cells such as these are due to the cheep cells being made of lower quality materials. some of the differances include 1: lower chemical-electrical conversion efficiency 2: lower capacity 3: faster self-discharge rate 4: shorter life span these characteristics dont ruin their functionality though, they are wonderfully useful even at the worst quality. ~~music used~~ Zelda Wind Waker: departure Scrapheap Challenge (junkyard wars) background music several songs from Jersey Devil for playstation 1

NexGen Lithium Batteries – 12V Replacement for Marine, Solar, RV, Golf Cart Batteries
NexGen Lithium Ion Batteries are the future of sustainable energy! Weighing up to 75% less than the standard lead acid battery, Lithium Batteries can significantly reduce the weight of your vehicle thus improving performance. Built to last, Lithium Ion Batteries have a life span of up to 10 times longer than traditional lead batteries. Battery life is measured in cycles and a NexGen Lithium battery will perform like a champ for over 5,000 cycles at 100% DOD compared to a lead acid battery which will cycle 500 times at 80% DOD. So that is 10 lead batteries you would have to buy to last the duration of a NexGen Lithium Ion Battery thus making lithium the cheapest option over time. Another cost factor to consider is the time it takes to charge a lead acid battery. NexGen Lithium Batteries can be fast charged to 100% unlike a lead battery. The final 20% of a lead battery cannot be fast charged like the first 80% and what often happens is a lead battery is pulled off the charger before the full charge occurs which prematurely ages the battery leading to an even shorter life span. NexGen Lithium batteries charge lightning fast and some will charge in as little as 30 minutes, talk about saving money! If for some reason you don’t have the time to charge to the battery to full 100% you will not damage it or jeopardize the life span and the battery will still produce consistently. Lead acid batteries are less efficient at storing power than lithium ion batteries. Lithium batteries charge at nearly 100% efficiency, compared to the 85% efficiency of most lead acid batteries. This could mean all the difference in the world when you are charging solar panels for your home, boat or RV. Also in cold weather or harsh conditions NexGen Lithium batteries will provide more than 85% of it’s energy as opposed to traditional lead acid batteries which provide around 30%. One of the best things about NexGen Lithium Batteries is that they don’t have to be stored upright like traditional acid batteries. This feature along with their extreme lightweight makes NexGen Lithium Batteries extremely versatile for a wide variety of storage applications. One of the best features of NexGen Lithium Batteries is that they are virtually maintenance free! Traditional lead acid batteries through time leak out acid and lead to corrosion of terminals and connections, not to mention the potential harm to living organisms and the environment. Your NexGen Lithium Battery will remain in the exact state that you purchased it with no leaks or corrosion to worry about. NexGen Lithium batteries are the future of energy and long term sustainability, superior in all aspects! Fuel your passion with a Nexgen Battery!

Understanding how Lithium-ion batteries fail
What happens when lithium-ion batteries overheat and explode has been imaged inside and out for the first time by a team led by UCL PhD student Donal Finegan (UCL Chemical Engineering) and Dr Paul Shearing (UCL Chemical Engineering). Understanding how Li-ion batteries fail and potentially cause a dangerous chain reaction of events is important for improving their design to make them safer to use and transport. Hundreds of millions of these rechargeable batteries are manufactured and transported each year as they are integral to modern living, powering mobile phones, laptops, cars and planes. Although battery failure is rare, earlier this year, three airlines announced they will no longer carry bulk shipments of lithium-ion batteries in their cargo planes after the US Federal Aviation Administration tests found overheating batteries could cause major fires. About UCL (University College London) Founded in 1826, UCL was the first English university established after Oxford and Cambridge, the first to admit students regardless of race, class, religion or gender, and the first to provide systematic teaching of law, architecture and medicine. We are among the world's top universities, as reflected by performance in a range of international rankings and tables. UCL currently has over 35,000 students from 150 countries and more than 11,000 staff.

Lithium Battery Heater -  DIY RV - How to build an Overlander
Ya' can't charge frozen Lithium. It's no secret, Lithium Batteries are fantastic, they can absorb a much higher percentage of the solar power as compared to Lead Acid batteries which lose much of the power to heat. This higher efficiency effectively doubles the amount of power we collect from the solar array. Li-Fe batteries can also sustain high current discharge without voltage sag, allowing us to use high current loads like an Induction Cooktop and Air Conditioner... All Powered by Solar! But they aren't without their own Achilles heel, and that's that they can't be recharged when frozen. In this video, I show how I installed a silicone heater mat in the pack and how I plan to use PID controller to keep a stable temperature. Also, Still learning some new video camera and audio gear, so this was partially an exercise in that too. Also Divinci Resolve 14...

Crazy eBay green laser pointer mod. 1mW to 1400mW++
What started as a simple desire for a brighter laser pointer got carried away and I ended up building the brightest laser pointer in the world. social media sillyness: instagram: https://www.instagram.com/styro.drake patreon: https://www.patreon.com/styropyro backup channel and b-side videos: https://www.youtube.com/channel/UCz-3epzOdIyu-aXdeUaVP1A discord: https://discord.gg/hVZMcWT I would love to give a big thank you to all my Patreon supporters. I would not continue to make videos if it weren’t for your generous support. I have yet to take a paid sponsorship and rely totally on donations and overlay ads to support these projects. I bought some green laser pointers on eBay recently and I have to say I was pretty disappointed with the lasers. Half of the laser pointers didn’t even turn on, and the ones that did work were very dim and covered in dents. I decided I should try opening them up and try to make them stronger. I started with the classic “pot mod” by cranking up the potentiometer on the driver. It made the laser brighter but it still couldn’t burn stuff. I scrapped the driver and hooked it directly to my variable PSU but that killed the laser almost immediately. I realized that I needed cutting edge laser technology in order to satisfy my extreme desires. I settled on using the Nichia NDG7475 laser diode as that is the brightest laser pointer out there that is still small enough to be jammed into a laser pointer housing. I hooked it up to a high efficiency buck converter for current regulation. I used a MOSFET as the main switching component as the stock switch in the laser pointer would not have handled the high current demands on the laser diode. I also used high drain 10440 li-ion batteries as the thought of 2 AAA batteries powering this new circuit is laughable. The modded laser pointer is awesome. In fact it is probably the brightest laser pointer in the entire world if your definition of a laser pointer is a laser that fits in a 2x AAA host. I test out its burning capabilities by pointing the laser at a bunch of stuff. Sometimes I don’t even know why I build crazy stuff like this. Song towards end of vid: town of 24 bars - Unicorn Heads

UK DIY Powerwall - 18650 Tesla style battery -  Lithium-ion Balancers - Part 9
Part 9 of the series to build a DIY Powerwall - home battery from old laptop batteries. Many people are using a BMS for balancing their Electric Bike smaller 18650 battery packs which is fine for the lower amp batteries. After researching I decided to go with the approach of Lithium-ion battery balancers to help maintain an even balanced voltage across my 7 batteries. These battery balancers have no voltage cut offs built in they are less complex and less electronics to fail. I'm using the inverter to manage the top and bottom battery bank cut offs. The battery balancers were purchased from Aliexpress.com I will post the link here in few days. The battery balancers are working really well and work by using dc voltage on the battery side and the battery balancer interconnects the green and blue cables use AC current to share the voltage across other batteries. 10Amp balance charge capable. Most BMS system provide much less than 10Amps which is why low cost BMS units are not very efficient when you have large amps in your batteries.

The Unreasonable Efficiency of Black Holes
Thanks to https://brilliant.org/minutephysics for sponsoring this video! Check out their black hole course at http://brilliant.org/minutephysicsblackhole Support MinutePhysics on Patreon! http://www.patreon.com/minutephysics Link to Patreon Supporters: http://www.minutephysics.com/supporters/ This video is about how efficient various reactions are at converting mass to energy (as we know from the Einstein mass-energy equivalence of E=mc^2). Antimatter is very efficient but it is not naturally-occurring. Chemical reactions like fire or explosions are very inefficient. Nuclear fission and nuclear fusion are better, but not amazing on an absolute scale. Non-rotating black holes (Schwarzschild) and rotating (Kerr) are by far the most efficient, due to their accretion disks and very small radius of their innermost stable circular orbits.

2018 Toyota Camry Hybrid System II Explained
http://www.Motorward.com - Subscribe For More Cool Videos: https://goo.gl/2nkv2Z The 2018 Camry Hybrid is available in three grades, LE, SE, and XLE. In addition to its enhanced handling and driving performance, the hybrid version of the new Camry achieves outstanding fuel efficiency with a best-in-class EPA-estimated mpg of 51 city/ 53 highway/52 combined on the LE grade, an impressive 30 percent increase for combined mpg, and 44 city/47 highway/46 combined on the SE and XLE, reflecting an increase of 21 percent for combined mpg. Dynamic performance is assured thanks to optimal control of the engine working in concert with the electric motor (MG2), while exemplary energy efficiency is achieved by using both electric motors (MG1 and MG2) for hybrid battery charging. Driving characteristics and trunk room are improved through the implementation of the new TNGA packaging as it allows for the hybrid system's battery pack to be moved from the trunk area to beneath the rear seat, positioning the battery weight at a lower center of gravity axis. The updated Power Control Unit (PCU) of the new hybrid system plays a key role in improving the operational efficiency of this eco-sensitive powertrain. Thanks to improvements in the conversion efficiency of the PCU and the transaxle/electric motor, they combine to reduce energy loss by a total of approximately 20 percent. Additionally, improvements to cooling system efficiency has reduced energy loss by about 10 percent. Just like the Prius, the PCU is lighter and more compact as a result of integrating microcontrollers and using a new power stack structure, allowing the unit to be packaged directly above the transaxle. This new design lowers the vehicle's overall center of mass and allows for a lower hood height. Another key change to the PCU is a revised DC-DC converter (converts a source of direct current from one voltage level to another) that sees its control output optimized - - including the conversion to AC power - - helping to reduce the vehicle's overall power consumption. What's more, the output filter for the DC-DC converter has been redesigned so that it is more dimensionally compact (improved packaging/weight savings) and produces less noise (reduced NVH). The 2018 Camry Hybrid is equipped with a Lithium-ion (Li-Ion) battery pack on the LE grade and Nickel-Metal Hydride (Ni-MH) battery pack on the SE and XLE. Along with the traditional Camry Hybrid system drive modes of NORMAL, ECO and EV, a new SPORT drive mode setting has been added that allows for an increase in power from the hybrid system for improved acceleration response relative to pedal input. The NORMAL, ECO, and SPORT modes can each be used while EV mode is activated. The Toyota Camry Hybrid also features the new Auto Glide Control (AGC), which helps to improve fuel efficiency by calculating an efficient coasting logic. When driving normally, engine braking will slow the vehicle down when the driver lifts off from the accelerator pedal. However, to avoid aggressive engine braking, AGC limits the loss of vehicle speed through an automatic drive setting that acts more like a neutral gear, allowing the vehicle to coast to the stoplight. An AGC indicator light is illuminated on the Multi-Information Display (MID) when AGC is in operation to alert the driver that less deceleration torque than normal is currently being used. Of note, AGC can only be activated when the vehicle is being operated in the ECO drive mode setting. A New Experience Focused on Vastly Superior Driving Dynamics While in the throes of development, the Camry's engineering team had a huge challenge on their collective to-do list: Create a soul-stirring sedan possessing enhanced, praise-worthy driving dynamics. At the foundation of the Toyota Camry's sporty handling and enhanced ride quality is its high-strength body/platform structure. Through the increased use of ultra-high-tensile steel and the application of a new molding technology it delivers enhanced structural rigidity. Further aiding performance is an innovative new double wishbone rear suspension system that imbues the chassis with responsive handling and precise steering control while simultaneously delivering ride quality on par with premium luxury vehicles. A new four-point engine mounting system adds to the vehicle's civil road manners as it greatly reduces unwanted noise, vibration and harshness (NVH) from permeating into the passenger compartment.

How to make a 12V Lithium-Ion Battery for $23 @ 6Ah
In this short video, I'll show you how to assemble this 12V Li-ion battery setup for portable (QRP) HAM Radio operations. 20,000 mAh @ 3.7V = 74 watt-hours / 12V = 6Ah which is 1 Ah less than the 7Ah Lead-Acid battery. You can connect another battery pack in parallel for 12Ah @ $46. With this setup I save on a Battery Management System since I can just swap the batteries out and use a regular battery charger (of course you need a battery charger).

TP-4056 1-8 cell 18650 Lithium-Ion Battery Charger
Let's make a low cost 1-8 cell 18650 Lithium Ion battery charger. This was just a quick project I came up with to charge 1-8 18650 cells for a very low cost. The mini-USB connector is shaped a bit like the "pin" on a dovetail joint and all I needed to do was cut the "tail" in the base of the battery holder to fit the connector. If you make it a tight fit, no need for any glue. I had to remove a bit of the bottom plastic to clear the components atop the TP4056 charger. Closeup photo below: https://drive.google.com/open?id=0B89_DmuFw50kTXVjMlo0ZGZJM1U Then all 4 red wires solder to the battery "+" pad and the 4 black wires to the battery "-" pad. I later put a few strips of electrical tape over the exposed wiring to insulate and protect it. To use, just plug in 1 or more 18650 cells. This charger runs up to 4.2V @ 1A. Each cell you add cuts the per-cell charging current. I mainly use this charger to recharge batteries after I have run a discharge test. So I'll throw in 4 pairs of cells sitting at about 3V and let them charge at 125mA/cell for a day or so. This way I'm not tying up a balance charger to do this. This charger is also good if you have sub-3V 18650 cells that you want to slowly bring back to see if they hold a charge. Total cost US$2.33 for the holder and $0.33 for the charger: 10 Pcs 5V Mini USB 1A TP4056 Lithium Battery Charger Module: http://www.ebay.com/itm/191600144163 Plastic Battery Holder Storage Box Case For 4x 18650 Rechargeable Battery: http://www.ebay.com/itm/281871948016 This was partly inspired by Paul Kennett's 20-cell 18650 charger: https://youtu.be/9aT8FVOblEY Be sure to rate, comment and share And as always, thanks for watching SOUNDTRACK: Lousiana Fairytale by Austin Rogers http://drfiddle.com/show_tune.php?id=94

New Vistas in Electrochemical Energy Storage
The widespread integration of renewable, intermittent energy sources such as wind or solar is dependent upon the development of efficient large-scale energy storage systems for load-leveling the electric grid. Similarly, the acceptance of plug-in hybrid electric—and especially pure electric vehicles—hinges on the availability of intermediate scale, safe, low-cost energy storage batteries to provide practical driving ranges. These approaches can help mitigate CO2 emissions and urban pollution, but it is widely acknowledged that traditional Lithium-ion batteries—which work on the principle of reversible storage of electrons and Li-ions in bulk materials—are approaching their limits. This presentation focused on the challenge to find better electrochemical energy storage systems that go “beyond Li-ion” batteries. Topics encompassed multivalent intercalation batteries and cells that operate on the basis of “chemical transformations.” These both represent exciting new technologies that could meet the needs for high energy density storage. Yet many barriers remain to realizing their full promise, especially for automotive applications. They require cleverly designed materials for the electrodes, different electrolyte strategies than those used for Li-ion batteries and advanced electrode architectures. If the hurdles can be overcome, then energy storage technology has a much better opportunity to change the way we manage energy. In this seminar, University of Waterloo's Linda Nazar discussed the research in the Electrochemical Energy Research Centre lab at the University of Waterloo that is aimed at addressing the above challenges. This talk was presented on September 7, 2016 as part of the IHS Markit Seminar Series. About the speaker: Linda Nazar was educated at UBC and the University of Toronto where she received her Ph.D. degree in materials chemistry. After a Postdoctoral Fellowship at Exxon Corporate Research, in 1987 she joined the University of Waterloo. She was promoted to full professor in 2000 and has established the Electrochemical Energy Research Centre. She has been an invited professor at the IMN/Université de Nantes, the Materials Science department in UCLA, the CNRS in Grenoble, France; and at Caltech. Nazar has achieved international recognition as a leader in the areas of solid state chemistry, electrochemistry, energy storage and materials science. She has co-authored over 200 publications, and has 8 patents. She is listed in the 2014 Highly Cited Research List (Web of Science).

(Part 2) PowerAdd Charger Center portable Li-Ion battery - charging with solar panels
⚡️ October 16, 2017 - Doing a "shakedown" of this PowerAdd portable battery "ChargeCenter" with Li-Ion batteries and a 100w modified sine wave inverter. It really isn't a "generator" per se (does NOT come with solar panels). However, in this test, I hook up two 50w Mohoo mono flexible solar panels and see "how it performs". I made this video to help/educate others (esp those w/o power in Texas, Florida, and Puerto Rico). Something like this can provide a little bit of comfort during a terrible situation. So, if you add some solar panels (like the ones I have)...total cost would be around $350 or so. Likes: Really good battery life for such a small unit (can take those Li-Ion batteries down to "0"). Multiple USB outlets, 12v outlets, one 19v outlet, stupid bright LED light, inverter works while charging (and the light), small/lightweight, comes with adapters, 12v solar panel charging w/o the need for a solar charge controller, fuel gauge (SOC) is really slick, removable inverter Dislikes: Modified sine wave inverter...would pay a little more for a pure sine wave inverter, black strap handle already fraying apart (looks to be non-replaceable), could be built a little more "rugged", only one USB QC 3.0 outlet (for rapid charging for Apple, iPhone, and other devices that have "Turbo" charging technology), 12v power socket charging cable came in bad (had to snip the end and make my own. It will now charge via using the car/truck's electrical system), USB outlets DO NOT work while charging source is plugged in (really bad idea) Bottom Line: Not a bad little battery/charging unit...but, def not "great". It has a lot of room for improvement. Add a solar panel and it becomes a "generator" per se. Def useful for many who need something small/emergency back up/keep in a vehicle...was able to run a 19" LED TV for 8+ hours (around 15w AC load). However, the modified sine wave inverter makes me reluctant to plug anything "expensive" into it that uses AC power. There are other ones out there available that aren't that much more expensive with a "pure sine wave" inverter and would be MUCH more efficient and easier on sensitive electronics. ~40w charging limit on any input source...prob not a "big deal" for most, this equates to about 5-hours charge time from "0-to-100" on the fuel gauge. 3/5 stars...and that is pushing it. Needs to be a pure sine wave inverter and USB outlets that work while charging...and a removable carrying handle with better material. I wish it would be "against the law" for any manufacturer to sell modified sine wave inverters... © 2017 by Chris DIYer. All rights reserved.

Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle models. Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours. Multiple batteries may be installed together for homes with greater energy need, up to 90 kWh total for the 10 kWh battery and 63 kWh total for the 7 kWh battery. Tesla Energy allows businesses to reduce peak demand charges, shift energy consumption profiles, and participate in available grid markets. For utilities, Tesla Energy solutions are turn-key, fully integrated systems, designed for long life and to serve a wide array of applications, including peaker replacement/capacity provision, T&D deferral, system firming, and other market participation. HOW IT WORKS Home solar installations consist of a solar panel, an electrical inverter, and now a home battery to store surplus solar energy for later use. SOLAR PANEL: Installed in an array on your roof, solar panels convert sunlight into electricity. HOME BATTERY: Powerwall stores surplus electricity generated from solar panels during the day or from the utility grid when rates are low. INVERTER: Converts direct current electricity from solar panels or a home battery into the alternating current used by your home’s lights, appliances and devices. COMPATIBILITY: Single phase and three phase utility grid compatible. EFFICIENCY: 92% round-trip DC efficiency. COST: $3,000 for 7 kWh, $3,500 for 10 kWh WARRANTY: 10 years. GIGAFACTORY: The Tesla Gigafactory 1[1] is a lithium-ion battery factory currently under construction being built primarily for Tesla Motors at the Tahoe Reno Industrial Center in Storey County, Nevada, US,[2][3] slated to be operational by 2017. By 2020, the Gigafactory is projected to achieve a production capacity of 35 GWh/year of cells and 50 GWh/year of battery packs. The 18650-size battery cells produced at the factory can be put in various devices such as drones, toys, and Grid energy storage.

The fourth mode (Electric Only Combined Engine On) is a series-parallel mode. The 2nd generation Volt's 5ET50 transaxle has 5 modes of operation. Two modes are electric only, one mode is a series-hybrid mode, and the Two remaining modes (series-parallel) allow the ICE to contribute torque to the wheels through the planet carrier of the input gear set. This transaxle is used in a Malibu Hybrid with only 4 modes (they removed the series mode). **1st generation Volt battery. If an individual cell is rated at 55.5Wh (using units of measure) Power (Wh) = EMF (V) x Current (A), then the current rating would be Wh/V = Ah. So 55.5Wh/3.7V = 15 Ah rather than the 55.5 Ah I mistakenly said/displayed in the video. 2018 Chevrolet Volt 355.2V Li-Ion Battery - Deep Dive Weber State University (WSU) - Department of Automotive Technology - Ardell Brown Technology Wing - Transmission Lab.

Will Chueh | Bridging the Enormous Span of Length Scales in Lithium-ion Batteries
Lithium-ion batteries are ubiquitous in everyday life, and are transforming mobility through electric vehicles, and electricity grid through the storage of intermittent renewables. Metrics such as energy density, lifetime and safety are controlled by phenomena that span enormous length scales, ranging from sub-Angrostroms to centimeters and beyond. Despite the significant progress over the past three decades, we still lack a complete understanding of how each length scale connects to one another, and most importantly, controls the behavior of the device. One grand challenge for materials used in lithium-ion batteries, like other so-called hierarchical materials, is to bridge the enormous span in length scales through integration of theory, advanced characterization, and data analytics. In this talk, I will provide an overview of our group’s recent activities on addressing this challenge through (1) a bottom-up approach, that is, understanding the fundamental nature of battery operation at the ion/electron, particle and agglomerate length scales, and (2) a top-down approach, that is, analyzing massive set of battery cycling data to discover new battery management protocols. This approach of merging predictive and data-driven design of lithium-ion batteries has already contributed to breakthroughs in several electrode materials.
