▎ 摘　　要

Lithium ion batteries (LIBs) are extensively used in numerous applications due to their impressive energy density and low memory effect. However, the inherently diffusion-controlled lithium storage limits their high-power applications. Herein, a novel surface redox capacitive lithium storage which originates from the deep oxidation of oxides during cycling of a hybrid consisting of nitrogen/phosphorous co-doped 3D graphene networks and Co-CoO/MnO nanoparticles (NPGCM), was employed to enhance the rate performance of anode for Li-ion batteries. The combination of surface pseudocapacitance with the diffusion-related lithium storage led to an extraordinary rate capability (1170.7 mAh g(-1) at 0.2 A g(-1) and 258.3 mAh g(-1) at 6 A g(-1)). Furthermore, the NPGCM hybrid exhibited excellent cyclic stability, showing a capacity of 397 mAh g(-1) after 1300 cycles at 4 A g(-1). Electron microscopy and spectroscopic investigations suggested the pseudocapacitance is originated from Mn3O4 generated during cycling. (c) 2019 The Electrochemical Society.
