Even if the terminals of the negative electrode are short-circuited for some reason, an accident such as abnormal overheating or ignition does not occur (claims 1 to 4). (2) Unlike the prior art, it does not require a movable part such as a shutter mechanism for covering the space between the positive electrode and the negative electrode terminal. Therefore, the battery has the same size as the battery pack without the shutter and has the accident prevention function as described above. A pack can be realized (claims 1 to 4). (3) Since there is no movable part such as the shutter mechanism, the reliability is high (claims 1 to 4). (4) Since it is a switch for magnetic application, there is no unnecessary power consumption for closing the circuit in the battery pack (claim 2). (5) Since the short circuit protection element such as a fuse, which is contained in the conventional battery pack, is simply replaced by the magnetic open / close switch,
There is no big difference in cost (claim 2). (6) Since the relay terminal is not exposed, there is no risk of short circuit between the relay terminal and the positive and negative external electrodes (claim 4).
