Cathode materials LiCo_0.2Ni_0.8O₂, LiCo_0.5Ni_0.5O₂ and LiCo_0.8Ni_0.2O₂ were synthesized by heating mixtures of LiOH with corresponding precursors Co_0.2Ni_0.8(OH)₂, Co_0.5Ni_0.5(OH)₂ and Co_0.8Ni_0.2(OH)₂ obtained from the alloy Co_0.2Ni_0.8, Co_0.5Ni_0.5 and Co_0.8Ni_0.2 by electrolysis, respectively. The experiment results show that all the cathode materials have excellent electrochemical performance, especially those prepared in oxygen atmosphere have high charge-discharge capacity and good recycle property.
