Abstract
A method of preparing a negative electrode for a lithium secondary battery, which includes forming a negative electrode mixture layer including a negative electrode active material on a negative electrode current collector, disposing lithium metal powder on at least a part of the negative electrode mixture layer, pressing the negative electrode mixture layer on which the lithium metal powder is disposed, wetting the pressed negative electrode mixture layer with a first electrolyte solution, and drying the wet negative electrode mixture layer. A battery including the negative electrode of the present invention has enhanced rapid charge/discharge characteristics and enhanced lifespan characteristics.
