Abstract

We reported a new type of rechargeable lithium-ion battery consisting of a structurally integrated 0.4Li2MnO3·0.6LiMnNi 0.4Co0.2O2 cathode and a hard carbon anode. The drawback of the high irreversible capacity loss of both electrodes, occurring at the first charge/discharge process, can be counterbalanced each other. The battery shows good reversibility with a sloping voltage from 1.5 V to 4.5 V and delivers a capacity of 105 mA h g-1 and a specific energy of 315 W h kg-1 based on the total weight of the both active electrode materials.
