ELECTRODE FOR LITHIUM SECONDARY BATTERY COMPRISING ELECTRODE ADDITIVE AND LITHIUM SECONDARY BATTERY USING THE SAME

摘要

Disclosed are an electrode including Li₂CuO₂ as an additive, and a lithium secondary battery having the same. The additive is added to a cathode as to adjust unbalance of the irreversible reaction between the cathode and an anode of the lithium secondary battery, thereby increasing the capacity of the lithium secondary battery without degrading performance of the lithium secondary battery after over-discharge of the lithium secondary battery.
