Moreover, the number of times of charging was limited, and the battery was not a semi-permanent battery. Next, a solar cell is a semi-permanent cell that does not require disposal or charging, but has a drawback of low electromotive force. Moreover, if there is no light energy such as sunlight around the solar cell, it cannot be charged, which is very inconvenient. Finally, the conventional generator is inevitably increased in size, and the devices that can be used are limited to those that consume considerable power. For this reason, it has been impossible to use it for small power-saving devices such as pocket radios and mobile phones.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to reduce the size by setting the outer shape of the battery in the shape of the battery housing of the equipment to be mounted.
It is an object of the present invention to provide a battery capable of semi-permanent use and adjustment of electromotive force under any environment.
