REGENERATING METHOD FOR ELECTROLYTE FOR ZINC-BROMINE BATTERY
PURPOSE:To establish a method for regeneration and reuse of an electrolytic solution of a zinc-bromine battery by effectively removing iron (Fe) from impurities in the electrolytic solution, and thereby eliminating ill influence of iron particularly upon an agent to turn bromine into a complex body....

| description | PURPOSE:To establish a method for regeneration and reuse of an electrolytic solution of a zinc-bromine battery by effectively removing iron (Fe) from impurities in the electrolytic solution, and thereby eliminating ill influence of iron particularly upon an agent to turn bromine into a complex body. CONSTITUTION:A hydrogen peroxide water is added (Step 102) to an electrolyte for a zinc-bromine battery, and iron contained in the electrolyte is oxidated from two valent into three, and thereupon an appropriate amount of aqueous ammonia is added (Step 103), and the iron contained is produced as a deposit consisting of hydroxides. By filtration of this deposit (Step 105), the iron contained in the electrolyte is removed. Adding of hydrogen peroxide water to the electrolyte will vary the pH of the deposit of hydroxides from 7.4 to 2, and adding of the aqueous ammonia makes pH of the liquid into 2. |
