The performance of a 2 kW, 10 kW h zinc-bromine battery is reported. The battery uses new carbon/PVDF bipolar electrodes and a circulating polybromide/aqueous zinc-bromine electrolyte. A turn-around efficiency of 65–70% is achieved. Disclosure is also given of an innovative non-flowing-electrolyte cell. This system is less complex and, hence, gives increased reliability and a higher return efficiency. A 25 A h single cell has completed over 400 cycles (100% depth-of-discharge) with a total return energy efficiency of over 75%. Such technology is extremely attractive for remote-area power-supply applications.
