One of the problems addressed by the present invention is to prevent battery deterioration, or prevent a drop in capacity during storage, maximize the charging/discharging performance of the battery, and to maintain battery charging/discharging performance over a prolonged period of time. A third electrode or a fourth electrode is positioned between the positive electrode and negative electrode of a rechargeable battery, and by applying a signal (current, voltage, etc.) inhibiting self-discharge to the third electrode or fourth electrode, the potential difference between the third electrode and the positive electrode, or the potential difference between the third electrode and the negative electrode, is adjusted, thereby controlling the chemical reaction within the rechargeable battery. |
