<p>In an electrolyte circulation type metal-halogen secondary battery, in which a cell chamber is divided into a cathode chamber 2 and an anode chamber 4 by a separator 5, and the cathode chamber 2 and anode chamber 4 are respectively connected to a catholyte storage tank 6 and an anoyte storage tank 7, it is possible to avoid bromine, discharged at the anode 3, passing into the cathode chamber 2 from the anolyte 8, by including in the anolyte a tertiary alkylamine as complexing agent. The resulting complex is oily and can be pumped with the anolyte 8 into the anolyte storage tank 7, where it can precipitate. Advantageously, the anolyte also contains an acid, most preferably in an amount equimolar with the amine.</p> |
