How a battery works - Curious
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
The electrochemical performance of a LiB (e.g. maximum capacity, rate capability, cycle efficiency and stability) is usually evaluated using a full cell consisting of …
