Zinc-bromine flowing electrolyte battery module (ZBM) delivers 10kWh of energy with a peak power rating of 5kW. Almost entirely made out of plastics and with a footprint of 800mm x 400mm (and 800mm high), it weighs 220kg, a fraction of the mass of comparable lead-acid batteries. It is designed for day-in day-out deep cycling with three to eight hour charge and discharge times and is the ideal building block for grid scale electricity storage systems or home backup power.
