Abstract:
(EN) This secondary battery comprises a positive electrode and a negative electrode, together with an electrolyte solution; and the negative electrode contains a plurality of negative electrode active material particles, a first negative electrode binder, and a plurality of second negative electrode binder particles that have an average particle diameter smaller than the average particle diameter of the negative electrode active material particles. The average particle diameter of the negative electrode active material particles is from 5 μm to 30 μm (inclusive). The first negative electrode binder contains at least one of a styrene-butadiene rubber and a derivative thereof. The second negative electrode binder particles contain at least one of a polyvinylidene fluoride and a derivative thereof; and the average particle diameter of the second negative electrode binder particles is from 0.1 μm to 10 μm (inclusive).
(FR) L'invention concerne une batterie secondaire comprenant une électrode positive et une électrode négative, en association avec une solution d'électrolyte; et l'électrode négative contient une pluralité de particules de matériau actif d'électrode négative, un premier liant d'électrode négative, et une pluralité de secondes particules de liant d'électrode négative qui ont un diamètre de particule moyen inférieur au diamètre de particule moyen des particules de matériau actif d'électrode négative. Le diamètre de particule moyen des particules de matériau actif d'électrode négative est de 5 µm à 30 µm (inclus). Le premier liant d'électrode négative contient un caoutchouc de styrène-butadiène et un dérivé de celui-ci. Les secondes particules de liant d'électrode négative contiennent un fluorure de polyvinylidène et un dérivé de celui-ci; et le diamètre de particule moyen des secondes particules de liant d'électrode négative est de 0,1 μm à 10 μm (inclus).
(JA) 二次電池は、正極および負極と共に電解液を備え、その負極は、複数の粒子状の負極活物質と、第1負極結着剤と、複数の粒子状の負極活物質の平均粒径よりも小さい平均粒径を有する複数の粒子状の第2負極結着剤とを含む。複数の粒子状の負極活物質の平均粒径は、5μm以上30μm以下である。第1負極結着剤は、スチレンブタジエンゴムおよびその誘導体のうちの少なくとも一方を含む。複数の粒子状の第2負極結着剤は、ポリフッ化ビニリデンおよびその誘導体のうちの少なくとも一方を含み、その複数の粒子状の第2負極結着剤の平均粒径は、0.1μm以上10μm以下である。
