BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a battery capable of enlarging a terminal to increase a current capacity by providing a liquid injecting hole and a safety valve in the terminal per se. SOLUTION: A liquid injecting hole 2a is formed at a positive electrode terminal 2 projecting from one end surface of a cylindrical battery case 1; in the meantime, a safety valve 3a is disposed at a negative electrode terminal 3 projecting from the other end surface. Since the liquid injecting hole and the safety valve are provided in the terminals per se, it is possible to prevent unsecureness of a space for installing the liquid injecting hole and the safety valve even if the terminals are enlarged so as to obtain a sufficient current capacity.
