Abstract
An energy storage device includes a metal case which houses an electrode assembly therein, and an insulation sheet mounted on a portion of an outer surface of the case. The case includes a projecting portion which extends in a thickness direction of the insulation sheet along an edge surface of at least a portion of the insulation sheet, and a distal end of the projecting portion projects from the insulation sheet.
Claims11
An energy storage device comprising:
- a metal case which houses an electrode assembly therein;
- and
- an insulation sheet mounted on a portion of an outer surface of the case,
- wherein the case includes a projecting portion which extends in a thickness direction of the insulation sheet along an edge surface of at least a portion of the insulation sheet, and a distal end of the projecting portion projects beyond the insulation sheet,
- wherein the case includes a cylindrical case body having an opening portion, the case body formed such that the insulation sheet is mounted on the case body along at least a portion of a peripheral edge of the opening portion, and
- a lid plate covering the opening portion, and having a peripheral edge portion which forms the projecting portion.
