Nonaqueous electrolyte battery, battery pack and vehicle

摘要

A nonaqueous electrolyte battery includes a flattened electrode group (1), a case (2), a positive electrode terminal (15) and a negative electrode terminal (16). The positive electrode terminal (15) is bent around one edge portion of the positive electrode terminal (15), curved toward the electrode group (1) and reaches a sealed portion. The other edge portion of the positive electrode terminal (15) extends from the case (2) through the sealed portion. The negative electrode terminal (16) is bent around one edge portion of the negative electrode terminal (16), curved toward the electrode group (1) and reaches the sealed portion. The other edge portion of the negative electrode terminal (16) extends from the case (2) through the sealed portion. The positive electrode terminal (15) satisfies formula (1) given below and the negative electrode terminal (16) satisfies formula (2) given below: t 2 × W 2 ‰¥ 0.25 �¢ S p t 3 × W 3 ‰¥ 0.25 �¢ S n
