Nonaqueous electrolyte battery, battery pack and vehicle

A nonaqueous electrolyte battery, comprising:

• a positive electrode;
• a negative electrode including a current collector and a negative electrode layer being supported by the current collector, and the negative electrode layer containing a titanium-based oxide having a Li ion insertion potential not lower than 0.4V (vs. Li/Li+);
• and
• a nonaqueous electrolyte;
• wherein:
• the negative electrode has a porous structure;
• a pore diameter distribution of the negative electrode as determined by a mercury porosimetry, which includes a first peak having a mode diameter falling within a range of 0.01 to 0.2 μm, and a second peak having a mode diameter falling within a range of 0.003 to 0.02 μm;
• a volume of pores having a diameter of 0.01 to 0.2 μm as determined by the mercury porosimetry is 0.05 to 0.5 mL per gram of the negative electrode excluding the weight of the current collector;
• and
• a volume of pores having a diameter of 0.003 to 0.02 μm as determined by the mercury porosimetry is 0.0001 to 0.02 mL per gram of the negative electrode excluding the weight of the current collector.
