Patent ID: 8568927

Claim:
A nonaqueous electrolyte battery comprising: a positive electrode; a negative electrode containing a lithium compound and a negative electrode current collector, and the negative electrode current collector supporting the lithium compound and comprising at least one kind of material selected from the group consisting of aluminum and aluminum alloys containing at least one kind of element selected from the group consisting of Mg, Ti, Zn, Mn, Fe, Cu and Si; 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.
