Negative electrode for lithium secondary battery, method of producing the same and lithium secondary battery including the same

Abstract

A negative electrode for a lithium secondary battery, a method of producing the negative electrode, and a lithium secondary battery including the negative electrode. Specifically, the negative electrode can reduce the initial irreversibility of the negative electrode because lithium metal ions are diffused into the negative electrode active material layer by pre-lithiation, and the negative electrode active material layer into which the lithium metal ions are diffused includes a plurality of line-shaped concave portions, so that when the lithium secondary battery is produced later, the concave portion keeps an electrolyte solution therein well to improve the impregnability of the electrolyte solution, thereby ultimately improving the electrochemical performance of the lithium secondary battery.
