As a result of investigating the cause, it was found that in this battery, the electrodes in particular expand even slightly during the charging and discharging process, similar to other batteries that use a solution as the electrolyte. In the case of a battery using such a solution, the solution is a major cause of expansion, which can be clearly observed from the external appearance.

After adding a step of adhering these two plates at the battery periphery, a thin plate made of metal and resin is used as a battery case, and the battery is constructed by adhering, particularly heat-sealing, at the battery periphery. As a result, in the present application, a battery can be obtained in which the electrode and electrolyte layers are firmly bonded, so that the phenomenon of expansion even slightly during the charging and discharging process is suppressed, and therefore the internal resistance does not increase and the battery can be easily compressed. Since deterioration of the electrolyte due to moisture from the atmosphere can also be prevented, excellent discharge performance and self-destruction properties can be obtained, and furthermore, the capacity does not decrease with a relatively small number of cycles.
