Title: LITHIUM ION BATTERY AND PRELITHIATION METHOD OF ANODE
Abstract:
Provided is a novel method for prelithiating an anode of lithium ion batteries, comprising 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℃ lower than the first temperature. Also provided is a lithium ion battery comprising an anode thus prelithiated.
