To provide a positive electrode for a lithium secondary battery having superior cycle characteristic configured, such that the coating ratio of a surface of a positive electrode active material of a binder and a conductive agent is not under a certain ratio by using stable positive active material.
An electrode for a lithium secondary battery formed by binding a positive electrode active material 1, including a lithium transition metal compound oxide and a conductive agent 2 as a binder 3, is configured so that before charging and discharging, at least 80% of a surface of the positive electrode active material 1 is coated on one side of the conductive agent 2 and the binder 3 and after exceeding 100 cycles of charging and discharging of maximum current amount, capable of charging and discharging reversibly at 60°C, at least 50% of a surface of the positive electrode active material 1 is coated in one side of the conductive agent 2 and the binder 3.
