Abstract:
To improve the cycle performance and charge/discharge capacity of oxide anode material,nano CuO-Co3O4-NiO composite oxide powder is synthesized by precipitation method as anode materials for lithium-ion batteries.Its crystalline structure is analyzed by X-ray diffraction,its morphology is characterized by transmission electron microscope,and its electrochemical performance is tested.The results show that nano CuO-Co3O4-NiO composite oxide can be obtained by precipitation method with the as-prepared particle size of 10-30 nm; the discharge capacity retention of nano CuO-Co3O4-NiO composite oxide is 94% from the 40th cycle to the 50th cycle.
