Document Type and Number:
Japanese Patent JP6540476
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a secondary battery capable of suppressing generation of internal short circuit caused by a foreign substance.SOLUTION: A secondary battery includes: an electrode body 20 configured by laminating a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode; and an internal member 200 arranged on the outside of the electrode body 20 in a lamination direction. The internal member 200 includes a first conductive member 110 conducted to the positive electrode; a second conductive member 120 conducted to the negative electrode; and an insulation member 130 interposed between the first conductive member 110 and the second conductive member 120. The first conductive member 110 is mutually stuck to at least an outer edge portion out of a face opposed to the insulation member 130 and the second conductive member 120 is mutually stuck to at least an outer edge portion out of a face opposed to the insulation member 130.SELECTED DRAWING: Figure 2
