| description | PROBLEM TO BE SOLVED: To provide a power storage device which can adequately prevent an overcharged state from being continued.SOLUTION: A power storage device comprises: a positive electrode; a negative electrode; a separator disposed between the positive and negative electrodes; and an electrolyte solution impregnated into the separator. At least one of the positive and negative electrodes has: an electrode base material; a conductive layer overlying on the electrode base material and including polyvinylidene fluoride and a conductive assistant; and an active material layer overlying the conductive layer. The electrolyte solution includes 0.5-4.0 mass% of biphenyl. The conductive layer includes 2 g/mor more of the polyvinylidene fluoride.SELECTED DRAWING: None
【課題】過充電状態が継続することを十分に防止できる蓄電素子の提供。【解決手段】正極と、負極と、正極及び負極の間に配置されたセパレータと、セパレータに含浸された電解液と、を含み、前記正極及び負極の少なくとも一方は、電極基材と、該電極基材に重ねられポリフッ化ビニリデン及び導電助剤を含む導電層と、該導電層に重ねられた活物質層とを有し、前記電解液は、ビフェニルを０．５質量％以上４．０質量％以下含有し、前記導電層は、前記ポリフッ化ビニリデンを２ｇ／ｍ２以上含有する、蓄電素子。【選択図】なし |
