PROBLEM TO BE SOLVED: To solve problems that, although a magnesium battery is an energy source full of promise, its degree of recognition is low, which prevents its spread, and that a portable light by a simple emergency battery that is convenient for carrying is demanded because, with respect to a normal battery, there is uncertainty in long-term storage, and it takes a lot of space that brings about inconvenience in carrying, and it is not low in cost, and that spread and recognition of the magnesium battery are demanded.SOLUTION: The spread of the magnesium battery is aimed by utilizing the efficiency of the magnesium battery for emergency. A plurality of units of electromotive layers each obtained by laminating a magnesium plate, an impregnated separator, and a carbon sheet, are arranged on the same surface of a support card that configures a conduction circuit, and sandwiched and unified by the other support cards each configuring the other conduction circuit. Thereby, a card battery that has a potential of an electromotive force while being thin in shape, and that generates electricity by being impregnated with water and electrolyte, can be obtained. |
