PURPOSE:To educe a metal uniformly on a neg. electrode by installing a valve on a complex body supply path, which supplies B complex stored in a B complex storage to a pos. electrode side reaction trough, opening this valve at the time of electric discharging, and closing at charging. CONSTITUTION:A control device 50 controls pumps 30, 42 and a valve 34 at the time of electric charging, discharging, and leaving a battery concerned, wherein the valve 34 is opened at discharging. B complex stored in a complex storage 32 is supplied to a pos. electrode side reaction trough 10a and supplies B to a pos. electrode 12. A pos. electrode side electrolyte 16b in a pos. electrode solution storing trough 24 is circulated to a neg. electrode side reaction trough 10b, and Zn ions are dispersed in the neg. electrode side electrolyte 16b. The valve 34 is shut at charging, when B complex produced in the pos. electrode side reaction trough 10a is precipitated bit by bit in the complex storage 32 and separated. which lessens the complex density in the pos. electrode side reaction trough 10a at charging. This provides uniform electroprecipitation amount of Zn on a neg. electrode 14. |
