How do lithium-ion batteries work? - Explain that Stuff

Aug 03, 2018 · The positive electrode is typically made from a chemical compound called lithium-cobalt oxide (LiCoO 2) or, in newer batteries, from lithium iron phosphate (LiFePO 4). The negative electrode is generally made from carbon (graphite) and the electrolyte varies from one type of battery to another—but isn't too important in understanding the basic idea of how the battery works.
