Original Abstract Submitted
A non-aqueous electrolyte rechargeable battery includes an electrode body, a negative electrode current collector, and a positive electrode current collector. The electrode body includes a stack of a negative electrode sheet, a positive electrode sheet, and a separator. The negative electrode sheet includes a negative electrode base, a negative electrode mixture layer, and a negative electrode connecting portion. The positive electrode sheet includes a positive electrode base, a positive electrode mixture layer, a positive electrode connecting portion, and an insulating protective layer. The insulating protective layer includes an outer insulating protective layer on a surface relatively far from the positive electrode current collector in a stacking direction of the electrode body and an inner insulating protective layer on a surface relatively close to the positive electrode current collector in the direction. The outer insulating protective layer has a larger thickness than the inner insulating protective layer.
