Abstract

original image

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.
