PURPOSE: To provide a nonaqueous solvent secondary battery having a large capacity. CONSTITUTION: This nonaqueous solvent secondary battery is constituted of a position electrode capable of charging and discharging, organic solvent electrolyte, and a negative electrode mainly made of carbon material as an active material. The active material of the negative electrode has the specific surface area of 10m<2> /g or smaller the 10%-volumetric average grain size of 0.5-5μm, the 50%-volumetric average grain size of 2-20μm, and the 90%-volumetric average grain size of 10-80μm. |
