A Novel Lithium-Doping Approach for an Advanced Lithium Ion Capacitor

A new lithium‐doping method using a stable lithium metal oxide, Li2MoO3 as an alternative lithium source is proposed. By incorporating Li2MoO3 into cathodes, the necessary lithium‐doping process of lithium ion capacitors can be simplified and made more effective. At the same lithium‐doping level, be...

Zusammenfassung:	A new lithium‐doping method using a stable lithium metal oxide, Li2MoO3 as an alternative lithium source is proposed. By incorporating Li2MoO3 into cathodes, the necessary lithium‐doping process of lithium ion capacitors can be simplified and made more effective. At the same lithium‐doping level, better capacity and rate capability are obtained than for the conventional method using metallic lithium.
