A novel high specific capacity hybrid cathode material was designed by increasing the specific capacity of cathode material to improve the discharge performance under large current. The carbon fluoride-sulfur hybrid material was prepared through grinding, dispersing and melt-diffusion treatment. Electrochemical tests and analysis showed that the new material could achieve synchronous improvement of capacity and high current discharge performance. At the same time, it has the capacity of secondary reversible cycle charge and discharge. The research results show that the energy density and power density of carbon fluoride-sulfur cathode have outstanding advantages, it can be significantly improved at different current densities. The energy density and power density are increased by 433% and 10.7% respectively than that of the pristine carbon fluoride cathode.
