PURPOSE:To ease control of halogen concentration in a system by circulating carrier gas in a battery system, and controlling the volume and path of the carrier gas. CONSTITUTION:An electrolyte is circulated between a battery part 1 and an electrolyte bath 2 with a pump 5. Halogen gas is generated in the battery part during charge, and circulated among the battery part 1, and an absorbing bath 3, and the electrolyte bath 2 with a pump 4, and absorbed in the absorbing bath 3. A given volume of inactive gas such as He and Ar is circulated in the gas circulation line as a carrier gas. Since halogen is transferred with carrier gas stream, even when the volume of halogen is largely varied, the gas stream in the whole circulation line is always kept, and easily controlled. To taken out the halogen from a solvent, a valve 7 is closed and a valve 6 is opened, and carrier gas is supplied into the solvent and taken out with carrier gas. Although the generating volume of halogen varies with the temperature of the solvent, it can freely be varied by controlling the flow rate of the pump 4. |
