▎ 摘　　要

NOVELTY - A prelithiated anode comprises an anode active material (A) having maximum lithium storage capacity, and a protective polymer (B) that prevents exposure of the prelithiated anode active material to open air, or bonds the prelithiated anode active material for improving a structural integrity of the prelithiated anode. The anode active material is prelithiated to a level of lithium interaction or degree of prelithiation 5-100% of maximum lithium storage capacity; The protective polymer has a lithium-ion conductivity 10-8-5×10-2seconds (S)/cm, at room temperature. USE - Prelithiated anode is used in lithium-ion battery (claimed). ADVANTAGE - The prelithiated anode enables lithium-ion battery to exhibit a high cycle life, high reversible capacity, low irreversible capacity, and compatibility with commonly used electrolytes. The high-capacity anode active material prevents the rapid capacity decay of lithium battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for lithium-ion cell which comprises prelithiated anode, a cathode containing cathode active material, and ion-permeable separator disposed between the prelithiated anode and the cathode.
