The battery stack is a critical part of the zinc-bromine flow battery, with electrodes that charge the battery by depositing zinc on a membrane and discharge it by reversing that process.
This process can sustain 10 kWh (kilowatt-hours) of energy storage capacity for the battery’s operating life.
Energy storage in residential and commercial settings
Redflow’s zinc-bromine flow batteries are designed for stationary energy storage applications in residential as well as industrial and commercial settings.
At Redflow’s Brisbane headquarters, the Thai-made battery stacks were installed on existing ZBM2 battery ‘tank sets’ and connected to performance-testing equipment.
After passing pre-delivery tests, these complete batteries are now scheduled for delivery to supply existing customer orders.
Redflow will continue to assemble, test and deliver limited quantities of ZBM2 batteries with Thai-produced battery stacks until it starts end-to-end manufacturing and testing of complete batteries in Thailand by June.
Once fully operational, the manufacturing line should be able to manufacture up to 250 complete batteries a month.
Redflow’s progressive commissioning of production from its Thai factory is part of the company’s strategic move to build high-quality zinc-bromine flow batteries closer to proven markets.
