Original Abstract Submitted
A non-aqueous rechargeable battery includes an electrode body in which a positive plate and a negative electrode plate are stacked in a stacking direction with a separator arranged in between. The positive electrode plate includes a positive electrode substrate, and a positive electrode mixture layer and an insulating layer arranged on each of two opposite surfaces of the positive electrode substrate. The positive electrode substrate includes a positive electrode uncoated portion. The electrode body includes a positive electrode current collector portion in which layers of the positive electrode uncoated portion are stacked in the stacking direction. A first insulating layer on a first surface of the positive electrode substrate, facing a center of the positive electrode current collector portion in the stacking direction, has a thickness that is greater than that of a second insulating layer on a second surface of the positive electrode substrate opposite to the first surface.
