Title:
POWER STORAGE DEVICE AND METHOD OF MANUFACTURING POWER STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2018107023
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power storage device capable of inhibiting degraded heat input part from being exposed.SOLUTION: An insulation sheet 33 covering an electrode assembly 12 has a pair of excesses parts 34b, 36b which protrudes from the side surface 12c of the electrode assembly 12 and which are opposed to each other. The pair of excesses parts 34b, 36b has a welded part 43 thermally welded. One excess part 36b of the pair of excesses parts 34b, 36b has a heat input part 43a to which heat is inputted during heat welding. The heat input part 43a constitutes a part of the welded part 43. The other excess part 34b has a cover part 34c covering the heat input part 43a from the outside.SELECTED DRAWING: Figure 5
