1485763 Separators for zinc-halogen cells UNIGATE Ltd 19 Aug 1974 [24 Aug 1973] 40299/73 Heading H1B A rechargeable zinc-halogen cell comprises a casing containing zinc anodes, halogen storage carbon/metal cathodes, a halogen gas inlet to the casing and a semi-permeable separator between each cathode and anode to prevent the passage through the separator of the halogen in solution. The separator enables the pH value of the electrolyte such as zinc chloride to be maintained at different values adjacent the cathode and anode. The halogen is preferably chlorine but may be iodine or bromine and the separator allows the passage of zinc and chloride ions but prevents the passage of chlorine molecules in solution. The membrane is of the radiation cross-graft type. |
