Abstract
A nonaqueous-electrolyte secondary battery prevents a short circuit between a positive electrode and a negative electrode even if pressure is applied from the outside, or stress is generated by folding applied thereon, during the battery manufacture, or when the battery is used as a product. The lithium ion battery includes a structure in which the positive electrode, gel-type macromolecular solid electrolyte layers in the positive electrode, separators, gel-type macromolecular solid electrolyte layers in the negative electrode, and the negative electrode are laminated; and two covering members are provided at ends of the positive electrode and the negative electrode, with two pairs of covering members disposed opposed to each of the two covering members.
