Zinc-bromine battery

摘要

A zinc-bromine battery is disclosed which includes anode and cathode reaction tanks separated from each other by a separator membrane for preventing self-discharge, and an electrolyte storage tank storing an electrolyte with a bromine complexing agent added thereto. Catholytes and anolytes are circulated between the cathode reaction tank and the anode reaction tank, respectively, and the electrolyte storage tank. The bromine produced in the catholyte is complexed by a complexing agent and is stored. A first connection pipe and a second connection pipe are provided for the purpose of forcibly mixing part of the anolyte and catholyte with each other therethrough. The first connection pipe receives part of the catholyte which has flowed from the cathode reaction tank to the catholyte storage tank from a position which is remote from an inlet for the catholyte, and supplies it to the anolyte storage tank. The second connection pipe, on the other hand, supplies part of the anolyte to the catholyte.
