摘要
1 Introduction As a promising cathode material for lithium ion batteries,LiNi1/3Co1/3Mn1/3O2 attracted intensive attentions.Owing to high specific capacity,long circle life and excellent safety,it may be an alternative candidate for LiCoO2.As a complex composite,however,it is difficult to synthesize phase-pure LiNi1/3Co1/3Mn1/3O2 by a simple mixed calcination method[1].From this concern,carbonate co-precipitation method,which can prepare homogeneous LiNi1/3Co1/3Mn1/3O2 with typical layered structure,becomes more and more popular.Much work have been carried out to optimize the reaction parameters during co-precipitating,such as temperature,feed rate and molar ratio,and acquired remarkable fruits[2].But there are few reports on investigating the morphology under various concentration of chelating agent.In this paper,metal carbonate sediments (generally called precursor) with various morphologies were prepared and electrochemical characteristics were discussed as well.
