During the charge and discharge process, Li+ is embedded and de-embedded back and forth between the two electrodes: when charging, Li+ is de-embedded from the positive electrode, embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; when discharging, the opposite is true. The tab is a raw material for lithium-ion polymer battery products, such as mobile phone batteries, Bluetooth batteries, laptop batteries, etc. used in our lives.
