(JA) セパレータ、およびセパレータを含む二次電池
Abstract:
(EN) Provided are: a separator that can be used for secondary batteries such as a nonaqueous electrolyte secondary battery; and a secondary battery that includes said separator. This separator has a first layer comprising a porous polyethylene and an organic additive. The first layer has a white index of 85-98, and drops of diethyl carbonate disposed on the first layer have a diminution rate of 0.048-0.067 mg/s. This separator may further include a porous material layer on top of the first layer.
(FR) L'invention concerne : un séparateur qui peut être utilisé pour des batteries secondaires telle qu'une batterie secondaire à électrolyte non aqueux; et une batterie secondaire qui comprend ledit séparateur. Ce séparateur comporte une première couche comprenant un polyéthylène poreux et un additif organique. La première couche a un indice de blanc de 85 0 98, et des gouttes de carbonate de diéthyle disposées sur la première couche ont un taux de diminution de 0,048 à 0,067 mg/s. Ce séparateur peut en outre comprendre une couche de matériau poreux au-dessus de la première couche.
(JA) 非水電解液二次電池などの二次電池に用いることが可能なセパレータ、およびセパレータを含む二次電池を提供する。多孔質ポリエチレンと、有機添加剤からなる第1の層を有するセパレータが提供される。第1の層のホワイトインデックスは85以上98以下であり、第1の層上に滴下したジエチルカーボネートの減少速度は、0.048mg/s以上0.067mg/s以下である。このセパレータはさらに、第1の層上に多孔質層を含んでもよい。
