Abstract:
A nonaqueous electrolyte battery includes a positive electrode containing an active material, a negative electrode, and a nonaqueous electrolyte, the negative electrode including a current collector and a negative electrode active material supported by the current collector, the negative electrode active material having a Li insertion potential not lower than 0.2V (vs. Li/Li+) and an average primary particle diameter not larger than 1 μm, and a specific surface area of the negative electrode, excluding a weight of the current collector, as determined by the BET method falls within a range of 3 to 50 m2/g.
