Want to include a small Lithium Ion or Lithium Ion Polymer battery into your next project? It's easy! Dave gives you the low down on how they work and how to charge them and select a suitable charging IC. NOTE: For safety you should always use circuit protected cells as per the larger cell I was holding up. It protects against over-discharge, over-voltage, shorts etc. (BTW, the reference to Lithium Ion Polymer being the same as Lithium Ion is in terms of charging, if that was not clear. The Ion Polymer type have polymer anode material and hence a different construction that allows the small pouch type cells shown in the video, and other thin odd shapes shown toward the end)

Ever wonder why the state of charge matters on a battery? It is actually critically important! In this video, we will discuss what state of charge and depth of discharge are and why they are important. In short, the deeper you discharge any type of battery the more you shorten its useful life. Some batteries are better than others at this, such as lithium ion, but it still plays an important part in your strategy and planning for your off grid solar panel system or e-bike battery or whatever project you are working on.

Getting Started in reclaiming 18650 Lithium Ion Cells from Power Tool and Laptop battery packs is a great way to get a pile of cells. But once you do... Then what?! Here I step through the process of Testing, Charging, and then Discharging the cells to find the capacity of each cell. Hopefully this helps to demystify topics surrounding how to process recovered 18650 cells. Tools Needed: - Basic volt/Multi-meter to check the cells voltage once liberated from the packs. - Lithium Ion safe charger units like the TP-4056's - RC grade charger/discharger unit, Like the Venom ProCharger used here, or a SkyRC IMax B6 or similar.

In this video I create discharge curves for my DIY lithium ion battery pack. This is something I have wanted to try for a while now. I wanted to test this for a couple of reasons. First I just wanted to see what I looked like and I also wanted to see how much capacity I was losing by not draining my battery all the way down to 2.5 Volts per cell.

Discharging During the first stage of discharge lithium atoms oxidize by forming Li+ ions and electrons, whereas Li+ ions move to the positive electrode diffusing through the electrolyte and the separator. The electrons flow from the negative electrode to the positive on the external circuitry, where the resulting current flow can be used for an application. At the positive electrode the electrons recombine with the Li+ ions and are stored in the molecular structure of the active material. Charging: If an external voltage with the same polarity is applied between the current collectors, the charge process will start. The lithium atoms leave the metal oxid structure and ionize into Li+ ions under the release of an electron of each one. In analogy with the discharge process Li+ ions diffuse to the negative electrode. At the surface of the graphite particles the Li+ ions and electrons recombine with each other forming neutral lithium atoms and are reintercalated into the molecular structure of the graphite particles.

The video is showing a few load tests on alum electrolyte converted cells. Although these tests are preliminary to some larger experiments they are still worth noting. The load tests showed unexpected good current results for cells that had been totally useless before the conversion. The battery voltage is typically less than a lead acid battery but the voltage has a flat discharge curve. The discharge curve if graphed would have shown and even decrease in in voltage during discharge. The cells seem to repeatably discharge to much lower voltages than would be acceptable in a standard lead acid battery. You can find all the most up to date information on John Bedini's channel where the chemistry is explained very well. http://www.youtube.com/user/Energenx/videos?flow=grid&view=0 Please visit John's channel and forum for very worth while instructions and applications.

[Background: as a young electrical engineer 30 years ago I designed power supplies and battery charging systems for mobile devices] I was very excited to be able to use the latest greatest automotive grade Lithium ion ferrous phosphate battery technology from Lithium Pros as they are vasty superior to lead acid batteries in several ways: very flat discharge curve (the battery voltage stays high); high high cranking amps without voltage drop (cranking at 12.8V, not 10-11v); very fast charging (all of the available energy from the alternator is immediately stored); many times greater cycle life; deep discharge capability (you can use all of the capacity without damage); and light weight. But the negatives are: poor performance in sub-zero temperatures; and a less than ideal match to standard automotive alternators that put out 14.4V when Lithium batteries don't want to be charged at more than 3.4V/cell = 13.6V. On-board battery management systems try to shunt the additional voltage and excess current thru internal discharge resistors and it sort-of works but the ideal situation would be an intelligent computer controlled alternator regulator that can rapidly charge the Lithium battery and then back off ... enter my latest project idea ... I built a circuit that allows full alternator voltage up to 13.6V and then limits it to 13.8V - it does this under ECU control by monitoring the battery voltage and then spoofing the alternator into thinking that it has reached 14.5V by outputting higher than actual voltage back to the alternator 'sense' wire. It uses a charge pump circuit to get 16v to the op amps, and the PWM output of the ECU to send signals to the circuit to increase or decrease the Vsense line. It works perfectly and now I have a charging system that won't limit the life expectancy of the $1200 battery I have. And I completed the associated battery charge/discharge ECU monitoring circuit which consists of a 75mV/200A shunt in series with the battery and a bi-directional differential voltage amplifier/monitor that puts out a 0-5V signal to the ECU (2.5V = 0 amps, 0V = 66 amps charging, 5V = 66 amps load) ... I also received my midnight blue headliner material from SMS - it is a perfect match to the VW OEM fabric and is nicely foam backed ...

Battery manufacturers specify battery capacity using a standard current drain level. This is likely to be different than the capacity you will achieve with the average current drain of your mobile device. Testing the battery using repeatable discharge currents similar to your device is essential to predicting actual achievable battery capacity and run-time. Agilent Technologies provides a one box solution that can provide precise, repeatable current loads and an integrated voltage and current measurement system.

Originally referring to Reedy's proprietary NiMH voltage enhancement technology, Zappers perfectly describe Reedy's new high-voltage LiPo battery chemistry. A 7.6 nominal voltage means that with a suitable charger, the battery can be safely charged to 8.7V (4.35V/cell). It is not a secret that more voltage equals more power, so there is no easier way to achieve a performance advantage than a higher charge voltage! But even when the typical 8.4V (4.2V/cell) charging limit is enforced, the battery still offers a significant advantage thanks to a flatter discharge curve, which results in more voltage deeper into the race. For those who race where approved batteries are required, 7.4V batteries are also available and feature the same discharge curve characteristics as the 7.6V versions. A high quality, durable hard case helps prevent damage while heavy-duty 5mm socket connectors keeps power-robbing resistance to a minimum. Pass-through sockets reduce jumper wire lengths in applications where two batteries are utilized. LiPo battery technology continues to progress and Reedy is proud to bring improved performance to the masses.

Discharging 100 AH Lithium LiFePo4 Cells. Using three dc motors to create an amp draw enough to drain the cells quickly. We are discharging our cells to allow for balancing of the cells on the bottom of the curve. Our discharge terminating voltage is at this time 2.4 with some at 2.38 or 2.35. From 2.4 to 2.5 is just seconds. and literally empty. I will be taking all those cells and discharging them to 2.3 at 75 amp draw. When reaching that goal voltage we terminate then connect the next cell until they are all done. We have 30 cells discharged and now ready to do a discharge to 2.3 volts. Then we will connect them in series and charge them up with our Elcon to 3.65 volts per cell.

This video shows Caleb's battery undergoing the 'Nail Penetration Test' without catching fire or explosion, unlike all others Lithium-based batteries. Caleb's battery does not have any thermal management issues (as you can view on the temperature reader's display) and does not loose its characteristics during and several months after the test (the voltage does not change as you can view on the meter's display). LinPoly™ is our patented unique technology that allows building "dry" high performance batteries of unprecedented safety and free of the thermal management issues associated with all other Lithium Ion technologies. By combining nanotechnology with the LinPoly™ technology, Caleb developed NANOFaB™, a Fabric Battery that could be tailored as a vest for the warfighters or integrated with the warfighter's uniform for better mobility (for example incorporated within the Kevlar vest or the Modular Lightweight Load-carrying Equipment - MOLLE Vest). This fabric battery is designed to replace the 10 to 30 pounds (4.5 to 13.6 kilograms) of batteries that troops carry to power devices such as radios, laser aiming sights, GPS, night-vision goggles, and mine detectors. NANOFaB™ could be further combined with a thin-film organic solar cell, giving it the capability of recharging itself when exposed to the natural or indoor light. Because of its safety characteristic, Caleb's fabric battery could be the answer for the upcoming consumer wearable electronics and electric and hybrid vehicles.

=================================================== Get the code from here: https://gum.co/SWtSK =================================================== A CCCV (Constant Current, Constant Voltage) is ideal for small batteries. Initially, the battery is charged at Constant Current. When the battery is nearly full, its voltage reaches the Constant Voltage setting of the charger, and the current decays exponentially as the battery gets a finishing charge. In this model I have build a CCCV charger on simulink that simulates this effect can be used to study and simulate this charging method maybe in a bigger system.

Global Li-Ion Graphite Corp. (CSE: LION) is focused on the exploration and development of graphite projects for the emerging energy storage industry. They intend to become a principle supplier of graphite to the rapidly growing lithium ion battery industry — including Tesla’s expansive Nevada Gigafactory and others slated to open globally. In this interview, Jason Walsh, Chairman of Global Li-Ion, speaks with Hannah Bernard on why the company is focused on graphite. Principle among reasons is that it is a major component of an ion battery, and graphite is one of the last energy metals to catch up to the likes of lithium and cobalt. With China producing approximately 80% of the world’s graphite and graphite oxide and India having an aggressive plan to implement fossil fuel-free vehicles by 2035, Global Li-Ion’s projects in Madagascar could prove to be in an ideal location. The Chedic Mine, outside of Carson City, Nevada, is 20 minutes away from Tesla’s Gigafactory. The third graphite project is the Neuron Project outside of Thompson, Manitoba — thought to be one of the richest graphite discoveries in North America. Jason discusses Global Li-Ion’s partnership with BEGO Technologies. BEGO has developed a process to take graphite to graphene. Jason explains that when graphite is replaced with graphene in an ion battery, the battery charges fasters, holds its charge longer, operates cooler, and becomes lighter in weight. Jason describes Global Li-Ion Graphite as a well-structured company that is well-financed. The company was able to use stock as a currency to secure premium assets, and he sees the market in the beginning of a commodity curve.

Most of us can check the voltage on our cells and with low-cost modules can determine the capacity they can discharge, but one of the most revealing attributes of a cell or battery's health is its INTERNAL RESISTANCE. I explain what it is, why it's an indicator of your cell's health and how you can measure it.
