锂离子电池

锂离子电池是一种二次电池（充电电池），它主要依靠锂离子在正极和负极之间移动来工作。在充放电过程中，Li+在两个电极之间往返嵌入和脱嵌：充电时，Li+从正极脱嵌，经过电解质嵌入负极，负极处于富锂状态；放电时则相反。

Lithium Ion Battery

A lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: during charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharge, the opposite is true.
