High complex-forming efficiency and battery efficiency are achieved in an electrolyte circulation type metal-bromine secondary battery of the kind in which the negatively active material is cadmium, zinc or lead, wherein the anolyte storage tank (21) comprises an anolyte zone (22) and a complexing agent zone (23) having a cross-sectional area smaller than that of the anolyte zone. Preferably electrolyte entering through inlet 27 passes through filter 28. As bromine-charged electrolyte rises through complexing agent zone, the bromine forms a complex and debrominated electrolyte leaves anolyte zone 22 through outlet 24. Complex passes out through outlet 25. Optionally the anolyte storage tank 21 can be surrounded by a catholyte storage tank (30). |
