Abstract
Official abstract text for this publication.
A secondary battery includes an electrode, a positive electrode current collector, a negative electrode current collector, a positive electrode terminal, a negative electrode terminal, and an insulating plate. The positive electrode terminal and the negative electrode terminal each have a main side surface and a sub side surface having an area smaller than that of the main side surface. The positive electrode terminal and the negative electrode terminal are arranged so that the main side surface of the positive electrode terminal and the main side surface of the negative electrode terminal face each other. The insulating plate is arranged between the main side surface of the positive electrode terminal and the main side surface of the negative electrode terminal.
First claim
Opening claim text (preview).
What is claimed is: 1. A secondary battery comprising: a positive electrode; a negative electrode; a positive electrode current collector provided at one end of the positive electrode in one direction; a negative electrode current collector provided at one end of the negative electrode in the one direction; a positive electrode terminal connected to the positive electrode current collector and formed in a flat plate shape; a negative electrode terminal connected to the negative electrode current collector and formed in a flat plate shape; a laminate exterior body provided around the positive electrode, the negative electrode, the positive electrode current collector, and the negative electrode current collector; an insulating plate that insulates between the positive electrode terminal and the negative electrode terminal, the positive electrode terminal and the negative electrode terminal each having a protruding portion protruding from the laminate exterior body in the one direction, each protruding portion having a main side surface and a sub side surface having an area smaller than that of the main side surface, the positive electrode terminal and the negative electrode terminal being arranged so that the main side surface of the protruding portion of the positive electrode terminal and the main side surface of the protruding portion of the negative electrode terminal face each other, the insulating plate being arranged between the main side surface of the protruding portion of the positive electrode terminal and the main side surface of the protruding portion of the negative electrode terminal; a fixing portion that fixes the positive and negative electrodes; and a holder that holds the positive electrode terminal and the negative electrode terminal so that the main side surface of the protruding portion of the positive electrode terminal and the main side surface of the protruding portion of the negative electrode terminal face each other, wherein: the insulating plate is connected to the holder, and the holder is fixed to the fixing portion. 2. The secondary battery according to claim 1 , wherein the insulating plate has a protruding portion protruding from the positive electrode terminal and the negative electrode terminal when the insulating plate is viewed in a facing direction in which the positive electrode terminal and the negative electrode terminal face each other. 3. The secondary battery according to claim 1 , wherein the laminate exterior body is provided around the fixing portion and the holder.
