摘要 |
The purpose of the present invention is to obtain a negative electrode for a large-capacity nonaqueous electrolyte rechargeable battery having good cycle characteristics. In the present invention, a negative electrode for a nonaqueous electrolyte rechargeable battery is used as a solution, said negative electrode being characterized by having an active material layer on a current collector, said active material layer containing at least granules, and one or more types of coating binder comprising any of a polyimide, polybenzimidazole, polyamide-imide and polyamide. The negative electrode is further characterized in that the granules contain at least active material particles containing: at least one type of element selected from a group comprising Si, Sn, Al, Pb, Sb, Bi, Ge, In and Zn; and a granulation binder. |
