- the battery ⁇ has half the amount of bottom swelling of the metal case with respect to the internal pressure as compared to the battery ⁇ , and has twice the metal case withstand pressure. This is because the bottom of the metal case of battery A was integrated with the negative electrode current collector by projection at five points, and the same effect as the effect of improving the pressure resistance was obtained when the bottom thickness of the metal case was increased. Think.
- the negative electrode current collector and the metal case are separated from the central portion and the peripheral portion of the negative electrode current collector facing the hollow cylindrical portion of the electrode plate group.
