Document Type and Number:
Japanese Patent JP6184104
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery in which poor welding of an injection hole and a sealing member, and electrolyte leakage are reduced.SOLUTION: A nonaqueous electrolyte battery includes a metallic exterior member 1, an electrode group 2, a nonaqueous electrolyte, an injection hole 1c, an insulating film 21, and a sealing member 23. The electrode group 2 includes a positive electrode 3 and a negative electrode 4, and is housed in the exterior member 1. The electrode group 2 is impregnated with the nonaqueous electrolyte.
