PCT No. PCT/AT93/00197 Sec. 371 Date Jun. 23, 1995 Sec. 102(e) Date Jun. 23, 1995 PCT Filed Dec. 22, 1993 PCT Pub. No. WO94/15372 PCT Pub. Date Jul. 7, 1994A process for charging and discharging zinc/bromine batteries with a plurality of anode and cathode chambers into and from which anolyte or catholyte fluids are fed and drained. Metallic zinc is deposited on the anode and atomic and/or molecular bromine is deposited at the cathode, and bromine is bonded in an only slightly water soluble complex with a complex-forming agent from the aqueous phase. The anolyte and/or catholyte fluids are circulated periodically. The oleophilic cathode phase is separated from the hydrophilic cathode phase. Only the aqueous phase of the catholyte is circulated through the cathode chambers, and the times at which the fluid is circulated is dependent upon the temperature of the anolyte in the anode chambers. |
