How the material of the battery electrode affects its performance and lifespan

Batteries are devices that store and release energy by moving charged particles called ions between two materials called electrodes. The electrodes are separated by a liquid or gel called an electrolyte, which contains ions and other molecules. When a battery is used, a thin layer of molecules forms on the surface of each electrode, called the solid-electrolyte interphase (SEI).
