Abstract

A negative electrode for a lithium secondary battery, a method of producing the negative electrode, a method of producing a pre-lithiated negative electrode by pre-lithiation of the negative electrode, and a lithium secondary battery including the negative electrode. The negative electrode can increase the capacity of a battery and improve the electrochemical performance by securing the initial reversibility of a negative electrode by pre-lithiation, and allow lithium ions to be diffused into a negative electrode active material layer during pre-lithiation without being lost.
