Patent ID: 8785052

Claim:
A nonaqueous electrolyte battery comprising: a positive electrode; a negative electrode containing a lithium compound and a negative electrode current collector, supporting the lithium compound; and a nonaqueous electrolyte, wherein a log differential intrusion curve obtained when a pore size diameter of the negative electrode is measured by mercury porosimetry has a peak in a pore size diameter range of 0.03 to 0.2 μm and attenuates with a decrease in pore size diameter from an apex of the peak, a specific surface area (excluding a weight of the negative electrode current collector) of pores of the negative electrode found by mercury porosimetry is 6 to 100 m 2 /g, and a ratio of a volume of pores having a pore size diameter of 0.05 μm or less to a total pore volume is 20% or more.
