内部短絡を生じる問題があった。Prior art and its problems In recent years, as electronic devices have become thinner, there has been a strong desire for thin and highly reliable batteries with a thickness of 0.5 mm or less. Batteries with a thickness of 0.5 mm or less that use polymeric solid electrolytes are more flexible than batteries that use inorganic solid electrolytes, and are characterized by the fact that they can be deformed to suit the application. These flexible batteries use a flexible current collector and outer case, so when a local force is applied to the battery, the separator inside the battery collapses and the positive and negative electrodes come into contact. However, there was a problem with the battery causing an internal short circuit.
