Title:
POWER STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2015130245
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power storage device capable of improving supply performance of an electrolyte to an electrode, capable of improving the exhaustion of an electrolyte by the expansion and contraction of an electrode due to charging/discharging, and capable of suppressing deterioration in battery performance due to the exhaustion.SOLUTION: A power storage device 100 accommodates a positive electrode 1 and a negative electrode 3 within an exterior member 7, the positive electrode 1 and a negative electrode 3 being arranged to sandwich a porous separator 5 including a nonaqueous electrolyte 9, as an electrolyte, impregnated therein. The power storage device includes electrolyte reservoirs 20 surrounding a side peripheral part 1a of the positive electrode 1 and a side peripheral part 3a of the negative electrode 3, respectively.
