The preparation of CuCo₂O₄ material with a suitable phase structure and grain size can improve its lithium storage performance. In this paper, CuCo₂O₄ hexagonal nanocrystal were successfully obtained by molten salt modified urea combustion method. Compared with the traditional high temperature solid state methods such as combustion method, rheological phase method and precipitation method, this method maintains the advantage of simple operation, and the particle size of the sample is smaller. The effect of heat treatment temperature on the lithium storage performance of CuCo₂O₄ was also studied systematically in this paper. The result shows that 800 ℃ is the best heat treatment temperature for CuCo₂O₄, and the sample synthesized by the molten salt urea combustion method exhibited the best electrochemical properties with a specific capacity of 705 mA h g^-1 after 100 cycles under a constant current of 200 mA g^-1 in the voltage range of 0.01-3 V. Therefore, a new strategy of high temperature solid state preparation has been developed in this paper, and the CuCo₂O₄ synthesized by this method is a promising anode material for lithium ion battery application.
