From the point of view of equipment protection, (1) ensuring safety in case the positive and negative terminals are accidentally short-circuited, and (2) ensuring rapid charging with a large current, preventing the battery from overcharging if the charger malfunctions. Therefore, in order to prevent the battery case from deforming due to the heat generated, there has been a demand for a built-in self-returning thermostat as a protective device.

、電池の発熱を阻止できなかった。Problems to be Solved by the Invention However, in such conventional storage batteries, the thermostat has the drawback that heat generation can only be transmitted to one cell among a plurality of cells that are in close contact with each other. Therefore, even if a cell that is not in close contact with the thermostat generates heat due to a short circuit between the positive electrode plate and the negative electrode plate, the heat generated by the cell is not sufficiently transmitted to the thermostat, and the heat generation of the battery cannot be prevented.
