Abstract:
(EN) The present invention provides a negative electrode for non-aqueous-electrolyte-based electrochemical elements having excellent producibility, a method for manufacturing the negative electrode, a lithium-ion secondary cell that has the negative electrode and has excellent charge/discharge cycle characteristics, and a method for manufacturing the lithium-ion secondary cell. This negative electrode for non-aqueous-electrolyte-based electrochemical elements is characterized in that a negative electrode mixture layer: contains at least a negative electrode active material doped with Li ions; and contains, as a binder, a copolymer having a unit that contains a hydroxyl group and a unit that contains an alkali metal salt group of a carboxyl group. This lithium-ion secondary cell is characterized in that the negative electrode for non-aqueous-electrolyte-based electrochemical elements is formed as a negative electrode.
(FR) La présente invention concerne une électrode négative pour des éléments électrochimiques à base d’électrolyte non aqueux ayant une excellente productibilité, un procédé de fabrication de l’électrode négative, une cellule rechargeable au lithium-ion qui comporte l’électrode négative et présente d’excellentes caractéristiques de cycle de charge/décharge, et un procédé de fabrication de la cellule rechargeable au lithium-ion. Cette électrode négative pour éléments électrochimiques à base d’électrolyte non aqueux est caractérisée en ce qu’une couche de mélange d’électrode négative : contient au moins un matériau actif d’électrode négative dopé avec des ions Li ; et contient, en tant que liant, un copolymère ayant un motif qui contient un groupe hydroxyle et une unité qui contient un groupe sel de métal alcalin d’un groupe carboxyle. Cette cellule rechargeable au lithium-ion est caractérisée en ce que l’électrode négative pour des éléments électrochimiques à base d’électrolyte non aqueux est formée en tant qu’électrode négative.
