Abstract
According to an embodiment, a nonaqueous electrolyte battery including an electrode group and a nonaqueous electrolyte is provided. The electrode group is formed by winding a positive electrode, a negative electrode, and a separator arranged between the positive electrode and the negative electrode. The tension modulus of the separator in the winding direction is within a range of 200 (N/mm2) to 2,000 (N/mm2).
