BATTERY CAN AND BATTERY USING THE SAME |
摘要 |
An Fe-Ni diffusion layer (3) is formed on the surface of a steel plate (2) containing Fe in an amount of 98 percent by weight or more, and the Fe/Ni ratio is adjusted within the range of 0.1 to 2.5. The steel plate (2) is shaped into a battery case (1) having a predetermined shape with predetermined dimensions such that the Fe-Ni diffusion layer (3) serves as the inner surface of the battery case (1). When a battery is produced using the battery case (1), corrosion due to over-discharge is suppressed even when the amount of Ni used is small. Therefore, the produced battery is excellent in leakage resistance. |
