Zinc-bromine batteries with improved electrolyte

Patent ·
OSTI ID:5760815
The coulombic efficiency of aqueous zinc bromine batteries can be increased if, in addition to the bromide ions required to be present in the electrolyte to charge the cell to rated capacity, chloride ions are added to the electrolyte in amounts sufficient to reduce the amount of free bromine present in the electrolyte during operation of the cell.
