摘要： The present invention provides a method for manufacturing a carbon-coated negative electrode active material for use in a non-aqueous electrolyte secondary battery, wherein a negative electrode active raw material including at least one of silicon oxide powder and silicon powder is coated with carbon by a catalytic CVD method. The present invention also provides a negative electrode material for use in a non-aqueous electrolyte secondary battery and a non-aqueous electrolyte secondary battery using the negative electrode active material. As a result, there is provided a method for manufacturing a negative electrode active material for use in a non-aqueous electrolyte secondary battery in which high battery capacity given by the silicon-based active material is maintained and a volume expansion and a break in the active material are suppressed.

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.
