Paper Title:
Study on the Rate Performance of LiCo1/3Ni1/3Mn1/3O2
  Abstract

Ternary lithium-ion battery is currently one of the hot cathode materials. In this paper, with acetate of nickel, manganese and cobalt as raw materials and lithium hydroxide as precipitation agent, LiCo1/3Mn1/3Ni1/3O2 was prepared by chemical coprecipitation method. LAND charge-discharge testing was used to study the electrochemical performance of materials at different rates (0.5C, 1C, 2C), and AC impedance spectroscopy was employed to study the rate performance and reasons of cyclical stability. The results showed that the stable SEM film formed under high rate was the main reason for the increased rate.
