The division of energy storage at dalian institute
of chemical physics developed zinc bromine single flow battery with high energy
density, simpl e structure, low cost, environment friendly. Successfully
assembled 1kW zinc bromine single flow battery system in 2016, battery shows
good cycling stability and energy efficiency, in 40mA/cm2 operating conditions,
energy efficiency remained at around 80%, for the same kind of battery the
highest international performance. Assembly testing of 5kW batteries is under
way. The battery cost is less than 2000 RMB/kWh.
