There are many accidents in which batteries are swallowed, and even in such cases, batteries with poor corrosion resistance can cause the contents of the batteries to leak out and have an adverse effect on the human body, so there was a desire for batteries with better load resistance. Further, as the size and thickness of the device have become smaller, there has been a problem of insufficient strength.
