摘要:
Disclosed is a nonaqueous electrolyte secondary battery which has a negative electrode containing silicon as a negative active material, a positive electrode containing a positive active material, a nonaqueous electrolyte and a separator. Characteristically, an additive which retards oxidation of silicon during operation of the battery is contained either in an interior or surface portion of the positive electrode, or in an interior or surface portion of the negative electrode, or in an interior or surface portion of the separator.
