Abstract:
1. A nonaqueous electrolyte battery comprising: a positive electrode; a negative electrode containing a negative electrode active material-containing layer which contains a lithium compound as a negative electrode active material, a binder and a conductor, and a negative electrode current collector supporting the negative electrode active material-containing layer; 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 an apex of peak in a pore size diameter range of 0.03 to 0.2 μm and does not have the apex of peak in a pore size diameter range of less than 0.03 μm, 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 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.
