A lithium-ion battery (sometimes Li-ion battery or LIB) is a member of a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.
Lithium-ion batteries are common in consumer electronics. They are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, small memory effect, and only a slow loss of charge when not in use. Beyond consumer electronics, LIBs are also growing in popularity for military, battery electric vehicle and aerospace applications. For example, lithium-ion batteries are becoming a common replacement for the lead acid batteries that have been used historically for golf carts and utility vehicles. Instead of heavy lead plates and acid electrolyte, the trend is to use lightweight lithium-ion battery packs that can provide the same voltage as lead-acid batteries, so no modification to the vehicle's drive system is required.
This is a segment from "How it's made" on lithium ion batteries
What is lithium ion? How do lithium ion batteries work? Lithium batteries work just like lead acid batteries, except they allow for the flow of lithium ions between the anode and cathode of the battery, as the electrons flow through the conductive connection. Lithium ion batteries are the popular choice for modern electric vehicles, due to their many advantages over lead acid batteries. -- Related Videos -- Batteries: http://youtu.be/vSzmbFf4Pyo Please feel free to rate, comment, and subscribe!

Smartphone, cordless screwdriver, laptops and defibrillators: Everyone knows the lithium-ion battery - or the Li-Ion Battery - for energy storage in a variety of modern appliances. A great future for the battery is predicted in the modern electric car. But how does this battery work? The animation shows how the components of the battery work together to release energy and to recharge the battery again. The goal: BASF wants to make the electric car of tomorrow reliable and suitable for everyday use with lithium-ion batteries. BASF helps to increase the mobility of the electric car by making the lithium-ion battery even more powerful. This film explains the principle of the lithium-ion battery: The battery is enclosed in an aluminum and copper layer. In between are a positive electrode, t...
Samsung has been in the news recently for their new Galaxy Note 7’s batteries exploding, something which has seen the smartphone manufacturer recall over two and a half million devices. What really is going on though? Why are these batteries exploding and is this something which could happen to any device? /////////////////////////// Follow us on Facebook: https://www.facebook.com/sciBRIGHT/ Subscribe to us on YouTube: https://www.youtube.com/subscription_center?add_user=sciBRIGHT

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)
How to build a lithium ion electric bike battery pack from recovered used laptop batteries. Save hundreds of dollars by salvaging 18650 li-ion cells from used or even dead laptop batteries bought off eBay. My pack is 24 volt 20AH which should hopefully provide a 30-45 mile range per charge on my ebike (and cost less than $150 dollars). In the video I show you how to calculate the capacity, then wire and test the completed battery. UPDATE: The battery had a total capacity of 19aH. The groups of cells were slightly out of balance (3.3v, 2.5v, 2.9v, 2.5v, 3.1v, 2.9v) so I could rearrange some cells and get a few extra miles, but I'm happy enough with the results.

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 diffu...
