Abstract

A series of LiNi_1/3Mn_1/3Co_1/3O₂ were synthesized by a combined hydroxides coprecipitation and calcination method.Effects of synthesizing temperature of coprecipitations and the Li∶M ratios on structure and electrochemical performance of the materials were studied.The results showed that materials synthesized with coprecipitation at room temperature(~20 ~(o)C) delivered the best electrochemical performance.Another series of cathode materials Li_XNi_1/3Mn_1/3Co_1/3O₂ with different Li∶M ratios were synthesized with this method.The results showed that sintering at high temperature could cause loss of LiOH,thus more LiOH should be added.It is demonstrated that Li_1.08Ni_1/3Mn_1/3Co_1/3O₂ had the best electrochemical performance.
