Nonaqueous electrolyte battery, battery pack and vehicle

A nonaqueous electrolyte battery comprising:

• a positive electrode comprising at least one kind of oxide selected from the group consisting of manganese dioxide, iron oxide, copper oxide, nickel oxide, lithium-manganese composite oxide, lithium-nickel composite oxide, lithium-cobalt composite oxide, lithium-nickel-cobalt composite oxide, lithium-manganese-cobalt composite oxide, lithium-manganese-nickel composite oxide, spinel-type lithium-manganese-nickel composite oxide, lithium phosphates having an olivine structure, iron sulfate and vanadium oxide;
• 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 m2/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.
