Abstract

A hierarchical micro/nanostructured Li-rich layered 0.5Li2MnO3·0.5LiMn0.4Ni0.3Co0.3O2 (H-LMNCO) material is prepared for the first time through the development of a solvothermal method, and served as cathode of lithium ion batteries. Electrochemical tests indicate that the H-LMNCO exhibits both a high reversible capacity and an excellent rate capability. The reversible discharge capacity of the H-LMNCO has been measured as high as 300.1mAh·g−1 at 0.2C rate. When the rate is increased to 10C, the discharge capacity could still maintain a high value of 163.3mAh·g−1. The results demonstrate that the developed solvothermal route is a novel synthesis strategy of preparing high rate performance Li-rich layered cathode material for lithium ion batteries.
