Abstract:
A case of an electrical storage device includes a case body, a lid, and a welded portion at an abutting portion where the case body and the lid are abutting against each other. In a cross-sectional view of the case along its extending direction, the welded portion has an interface existing at a boundary of the welded portion with the case body and the lid. The maximum dimension from an exposed surface of the welded portion to the interface is defined as a weld depth X. The dimension from the abutting portion to an edge of the welded portion in a direction along the exposed surface of the welded portion is defined as a weld width Y. The welded portion is configured to exist over the entire circumference of the case in a shape that satisfies an expression Y/X>1.

Claim (Index 11):
An electrical storage device comprising an electrode assembly and a case, which accommodates the electrode assembly, wherein\n the case includes\n a tubular case body, which has a bottom wall and an opening, and \n a lid, which closes the opening, \n the case body includes a circumferential wall, the circumferential wall has an opening end face, which surrounds the opening, and an outer circumferential surface, the opening end face has a case-side mating surface, which abuts against the lid, the lid includes\n an inner end face, which has a lid-side mating surface, which faces the case-side mating surface, and \n an outer circumferential surface, which surrounds the inner end face, \n the case has a welded portion existing over an entire circumference of the case at an abutting portion, which is a portion where the case-side mating surface and the lid-side mating surface are abutting against each other, the welded portion has a surface, which is exposed from the outer circumferential surface of the circumferential wall and the outer circumferential surface of the lid, a direction that connects the bottom wall of the case body and the lid by the shortest distance is defined as an extending direction of the case, in a cross-sectional view of the case along the extending direction, the welded portion has an interface existing at a boundary of the welded portion with the case body and the lid, a maximum dimension from the surface of the welded portion to the interface in a thickness direction of the circumferential wall is defined as a weld depth X, a dimension from the abutting portion to an edge of the welded portion in a direction along the extending direction is defined as a weld width Y, and the welded portion is configured to satisfy an expression Y/X>1 over the entire circumference of the case.
