Abstract
According to one embodiment, an electrode is provided. The electrode includes an electrode mixture layer and a current collector. The electrode mixture layer contains active material particles. The electrode mixture layer includes a first surface being in contact with the current collector and a second surface separated from the first surface by a thickness of the electrode mixture layer. The electrode mixture layer includes a first portion having the first surface and a second portion having the second surface. In the first portion, a first oxide layer is formed on the active material particle. In the second portion, a second oxide layer is formed on the active material particles. The thickness of the first oxide layer is more than the thickness of the second oxide layer.
