Abstract:
A negative electrode 1 for lithium secondary batteries, which can increase the charge/discharge capacity of a lithium secondary battery, includes a negative electrode current collector, a negative electrode active material layer, and a lithium layer. The negative electrode active material layer is disposed on regions and of the respective surfaces and of the negative electrode current collector. The lithium layer is disposed on uncovered regions and, which are regions of the respective surfaces and of the negative electrode current collector on which the negative electrode active material layer is not disposed. The lithium layer includes lithium.
