EP 91520 A1 19 Oct 1983, 19 pp. DESIGNATED STATES: R: DE, FR, GB, IT. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: H01M010-36; H01M002-40; H01M004-38. APPLICATION: EP 82-301919 14 Apr 1982. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) In the title battery a cell chamber is divided into a cathode and an anode chamber by a separator, and the cathode chamber and anode chamber are resp. connected to a catholyte-storage tank and an anolyte-storage tank. It is possible to avoid Br, discharged at the anode, passing into the cathode chamber from the anolyte by including in the anolyte a tertiary alkylamine as complexing agent. The resulting complex is oily and can be pumped with the anolyte into the anolyte storage tank, where it can ppt.In this experiment, several chemicals are used like 121-44-8 and 75-50-3 Advantageously, the anolyte also contains an acid, most preferably in an amt. equimolar with the amine. .
