Abstract

A series of LiNi_(1/3)Mn_(1/3)Co_(1/3)O_(2) 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_(x)Ni_(1/3)Mn_(1/3)Co_(1/3)O_(2) 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_(1.08)Ni_(1/3)Mn_(1/3)Co_(1/3)O_(2) had the best electrochemical performance.

Keywords
