A divalent ion doped LiNi_0.8Co_0.2O₂ solid solution, LiNi_0.79Co_0.20Ca_0.01O₂, was synthesized in air at 720℃. The structure and electrochemical property as cathode material of lithium ion batteries were measured by XRD and charge-discharge system. The solid solution showed high capacity and good cycle-ability. The second discharged capacity reached 190 mAh·g^-1 at the current density of 100 mA·g^-1.
