Abstract
According to one embodiment, an electrode is provided. The electrode includes a current collector and an electrode layer. The electrode layer is disposed on the current collector and includes lithium fluoride. A first content of lithium fluoride in a first region is 0.02% by weight or more and less than 2% by weight. The first region is adjacent to an interface between the electrode layer and the current collector, and has a first thickness equal to 20% with respect to a thickness of the electrode layer. A second content of lithium fluoride in a second region is from 2% by weight to 10% by weight. The second region is adjacent to a surface on a reverse side of the electrode layer, and has the first thickness.
