PROBLEM TO BE SOLVED: To provide an electronic device having a large capacity and a high reliability, and to provide a small-sized electronic device that can be installed indoors regardless of a large capacity.SOLUTION: An electronic device comprises a plurality of battery cells. Each of the plurality of battery cells comprises a first electrode, a second electrode, and at least an electrolyte between the first and second electrodes. With respect to a reaction product grown from at least one point on the first electrode surface by applying a current between the first electrode and the second electrode, a signal by which a current in a reverse direction to the current flows is applied to melt the reaction product from a front end or a surface of the reaction product. The plurality of battery cells are connected in series and stored in an underfloor space part surrounded by a foundation part and a floor of a building. |
