We reported a new type of rechargeable lithium-ion battery consisting of a structurally integrated 0.4Li(2)MnO(0.3)center dot 0.6LiMnNi(0.4)Co(0.2)O(2) 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.
