Abstract:
A lithium secondary battery including a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode, wherein the negative electrode is lithiated by pre-lithiation, a total capacity of a negative electrode active material of the negative electrode is larger than a total capacity of a positive electrode active material of the positive electrode, and a charge capacity of the negative electrode is smaller than a charge capacity of the positive electrode by the pre-lithiation.
