How Lithium Batteries Work How lithium-ion batteries work is very well explained in the video "How a Lithium Ion Battery Actually Works // Photorealistic // 16 Month Project". Although the demonstration shows a cylindrical lithium-ion battery, the underlying principle is the same for lithium-ion pouch and prismatic types of lithium-ion batteries. The three types of resultant "containers" for lithium-ion batteries are the pouch, cylindrical and prismatic.
There are five recognized main cathode chemistries, with slight variants, used to create Lithium-ion batteries. The LTO uses a different anode chemistry. The video, "Types of Lithium ion battery with application | Lithium ion battery types LCO, LMO, LFP, NMC, NCA, LTO" note the "safest types of chemistries".
Safety was THE most important factor when selecting the battery chemistry for my KISS Dead Rail system!  The graphic is from a Website titled, "A Guide To The 6 Main Types Of Lithium Batteries". This graphic is useful in determining the chemistry's relative safety. The spider diagrams show the safety line at the upper left side in this graphic. Like the previous referenced video, LTO (Lithium Titanate) and LFP (Lithium Iron Phosphate) are shown as the safest. LCO (Lithium Cobalt Oxide) and NCA (Lithium Nickel Cobalt Aluminum Oxide) are denoted as the least safe. LMO (Lithium Manganese Oxide) and NMC (Lithium Nickel Manganese Cobalt Oxide) falls in-between the safest and least safe. I have chosen to use Lithium Iron Phosphate, Lithium Manganese Oxide and Lithium Manganese Cobalt Oxide cylindrical batteries for use with my KISS Dead Rail system.
