Title:
POWER STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2019204669
Kind Code:
A
Abstract:
To provide a power storage device capable of restraining deformation of the overhang part of a power storage module.SOLUTION: Since a thick film part 26 is provided in the overhang part 24 of a power storage module 4 in a power storage device 1, in a situation where the internal pressure of an electrode laminate 11 increases in one power storage module 4 and the overhang part 24 deforms to the outside in the lamination direction D1, the thick film part 26 of the overhang part 24 of the power storage module 4 abuts on the thick film part 26 of the overhang part 24 of another adjoining power storage module 4. After the thick film parts 26 abut each other, further deformation of the overhang part 24 is suppressed. With such an arrangement, the power storage device 1 can restrain excessive deformation of the overhang part 24, while accepting initial deformation thereof to some extent.SELECTED DRAWING: Figure 5
