To optimize the potential window and maximize the utilization of the capacity of both negative and positive electrodes, rational design of electrode materials are critically important in full-cell construction of rechargeable batteries. In this work, we propose and fabricate a carbon-confined V 2 O 3 /Ni 2 P/C composite structure for excellent performance lithium ion batteries by taking advantage of the high capacity of V 2 O 3 and low potential of Ni 2 P. The full cell constructed with V 2 O 3 /Ni 2 P/C as anode and commercial LiMn 2 O 4 as cathode offers a record high energy density of 361.5 Wh kg –1 and excellent cycle stability, outperforming the state-of-the-art work reported in literature.
