摘要:
The present invention provides a negative electrode paste that is used to manufacture a negative electrode of a non-aqueous electrolyte secondary battery including: (A) a silicon-based negative electrode active material; (B) a binder containing at least one of a polyimide resin and a polyamide-imide resin; and (C) an ionic liquid. As a result, there is provided a negative electrode paste that can suppress an entire negative electrode from curling when a negative electrode paste is coated on a current collector and dried, and can produce a negative electrode having excellent cycle characteristics and large battery capacity.
