Zinc-bromine battery
First Claim
1. A zinc-bromine battery wherein catholyte and anolyte are respectively circulated betweena cathode reaction tank and an anode reaction tank which are separated from each other by a separator membrane for preventing self-discharge, anda catholyte storage tank and an anolyte storage tank, and whereinthe bromine generated in said catholyte is complexed by a complexing agent and stored, said battery comprising:
- a first connection pipe for receiving part of said catholyte which has flowed from said cathode reaction tank to said catholyte electrolyte storage tank from a position which is remote from an inlet for said catholyte and supplying said part of said catholyte to said anolyte storage tank; and
a second connection pipe for supplying part of said anolyte to said catholyte for the purpose of mixing;
wherein said catholyte and said anolyte are forcibly mixed with each other through said first and second connection pipes.

Abstract
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.
