Abstract

A new electrolytic method was developed to prepare LiCo_xNi_1-xO₂ as a cathode material of lithium-ion battery. Contrary to the traditional method, electrolytic method is a potential method with simple process to industrialization and no pollution. Metal cobalt and nickel were electrolysed in parallel to prepare the precursor of Co_xNi_{1- x}(OH)₂.Different compositional precursors could be conveniently prepared by changing electrolytic current. The LiCo_0.3Ni_0.7O₂ cathode prepared by this method was found favorable charge-discharge and cycle properties. For the LiCo_0.3Ni_0.7O₂ cathode material, the discharge capacities in the 1st and 50th cycles were 163 mAh/g and 140 mAh/g with charge retention of 86%.
