"textContent": "According to an embodiment, a nonaqueous electrolyte battery is provided. The nonaqueous electrolyte includes a negative electrode, a positive electrode and a nonaqueous electrolyte. The negative electrode includes negative electrode active material particles. The negative electrode active material particles include a spinel-type lithium titanate. The negative electrode has such a surface state that a ratio A/Aof an Li atom abundance ratio Ato a Ti atom abundance ratio A, according to a photoelectron spectroscopic measurement for a surface, is increased at a rate of 0.002 to 0.02 per cycle in a charge-and-discharge cycle test under the predetermined condition.",
