Lithium-ion batteries use lithium-containing compounds as the positive electrode. During the charging and discharging process, lithium ions are extracted and inserted back and forth between the positive and negative electrodes of the battery to achieve charging and discharging. The inside of a lithium-ion battery is mainly composed of a positive electrode, a negative electrode, an electrolyte and a separator. Lithium-ion batteries mainly rely 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+ deintercalates from the positive electrode and intercalates into the negative electrode through the electrolyte, […]
