The title cathode material for lithium ion battery was prepared by the sol-gel method and investigated by means of physical and electrochemical methods as the function of preparation conditions.Its structure and electrical behavior were characterized and measured by virtue of XRD technique,DSC,cyclic valtommetry and constant-current charging-discharging tests.The results show that LiNi_0.45Co_0.1Mn_0.45O₂ obtained from calcination at 700℃ for 7 h exhibited a specific discharging capacity up to 145 mA·h/g after 30 charging-discharging cycles at 3.0~4.3 V.
