Nonaqueous electrolyte battery, battery pack and vehicle

A battery pack comprising a nonaqueous electrolyte battery, the nonaqueous electrolyte battery comprising:

• a positive electrode;
• a negative electrode comprising an active material having a lithium ion insertion potential of 0.4V (vs Li/Li+) or more, a conductive agent containing a carbonaceous material, and a current collector supporting the active material and the conductive agent;
• and
• a nonaqueous electrolyte containing first sultones having an unsaturated hydrocarbon group,
• wherein a diameter distribution of pores of the negative electrode when measured by mercury porosimetry has a first peak having a mode diameter of 0.01 to 0.2 μm and a second peak having a mode diameter of 0.003 to 0.02 μm, and
• a volume of pores having a diameter of 0.01 to 0.2 μm and a volume of pores having a diameter of 0.003 to 0.02 μm, which are measured by the mercury porosimetery, are 0.05 to 0.5 mL and 0.0001 to 0.02 mL, respectively, per g of the negative electrode excluding the current collector.
