Abstract
A nonaqueous electrolyte rechargeable battery includes a positive plate, a negative plate, a separator that insulates the positive plate from the negative plate, and a nonaqueous electrolytic solution. The positive plate includes a positive current collector, a positive composite layer disposed on a portion of a surface of the positive current collector and containing a positive active material particle, and an insulation protective layer disposed on another portion of the surface of the positive current collector adjacent to the positive composite layer and containing an insulation particle. The insulation protective layer has a smaller thickness than the positive composite layer. The insulation protective layer has a greater porosity than the positive composite layer.
