Claim:
1. A negative electrode for lithium secondary batteries, the negative electrode comprising: a negative electrode current collector; a negative electrode active material layer disposed on a region of a surface of the negative electrode current collector; a lithium layer including metal lithium, the lithium layer being disposed on an uncovered region, the uncovered region being a region of the surface of the negative electrode current on which the negative electrode active material layer is not disposed; the negative electrode further comprising a negative electrode lead connected to the uncovered region of the negative electrode current collector, wherein the lithium layer is disposed at least partially between the negative electrode lead and the negative electrode current collector, the negative electrode further comprising the negative electrode lead connected to and welded on a top of the uncovered region of the negative electrode current collector, the lithium layer is beneath the negative electrode lead and is between the negative electrode lead located on the uncovered region of the negative electrode current collector and the negative electrode current color, and wherein the lithium layer is disposed under the negative electrode lead which is at least partially between the negative electrode lead and the negative electrode current collector.
