Recent technology improvements in Exxon's circulating zinc-bromine battery system

Conference ·
OSTI ID:6513209
Recent electrode and electrolyte performance on 500 wH and 3 kWh units indicates that Exxon's circulating zinc-bromine battery in 20 kWh designs will be capable of high energy density (65 to 70 wH/kg), and turn-around efficiency (65 to 70%). This performance, coupled with recent factory cost projections of $28/kWh (exclusive of R.O.I. and various indirect overheads), makes zinc/bromine an attractive advanced battery candidate for not only photovoltaic, but also electric vehicle and bulk energy storage applications. Recent technical developments in this program may be generally useful in other circulating electrolyte systems.
