Lithium Ion Battery and Prelithiation Method of Anode

A method for prelithiating an anode of lithium ion batteries includes the following steps: (a) charging the battery to a voltage from about 4.2 to about 4.5 V at a first temperature; and (b) discharging the battery to a voltage from about 2.5 to about 3.2 V at a second temperature which is about 20 to 40° C. lower than the first temperature. Also provided is a lithium ion battery having an anode prelithiated by the method.
