Abstract
An electrode for a non-aqueous electrolyte secondary battery, includes a current collector; a first electrode active material layer including a first electrode active material, arranged on a surface of the current collector; and a second electrode active material layer including a second electrode active material, arranged on a surface of the first electrode active material layer. The first electrode active material layer includes a binder in a crystallized state, and the second electrode active material layer does not include a binder. A thickness of the second electrode active material layer is 150 μm or more, and a total of a thickness of the first electrode active material layer and the thickness of the second electrode active material layer is 250 μm or more. A ratio of the thickness of the first electrode active material layer to the thickness of the second electrode active material layer is 0.108 or less.
