Basic Introduction To Lithium-ion Batteries

A lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between the positive and negative electrodes to work. In the charging and discharging process, Li+ is embedded and deembedded back and forth between the two electrodes: when charging, Li+ is deembedded from the positive electrode and embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; The opposite is true when discharging.
