  • Publication number: 20250074785
    Abstract: The present disclosure provides various characteristics of a method for the production of an ultra-pure zinc bromide and zinc chloride fluid blend in a reactor system, having reduced metal impurities for the use in battery electrolyte blends, by reacting chlorine with a mixture of zinc bromide and zinc. The method disclosed can be used in continuous flow or batch processing and uses a zinc bromide to aqueous solution as catalyst in a reaction with chlorine. Chlorine, whether in liquid or gas form, added into a reactor at a controlled rate reacts with bromide to generate bromine in a much faster rate that when the zinc bromide to aqueous solution would not be present. Any un-reacted zinc is then filtered out which will ultimately result in the ultra-pure zinc bromide and zinc chloride fluid blend.
