ZBM2 zinc-bromine flow battery with a battery stack made by Redflow factory in ThailandAustralian battery company Redflow Limited (ASX: RFX) has completed the first ZBM2 batteries using battery stacks made by its new Thailand factory, which are now ready for shipment to customers.

The battery stack is the critical part of the Redflow ZBM2 zinc-bromine flow battery, with electrodes that charge the battery by depositing zinc on a membrane and discharge it by reversing that process.

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.

Redflow CEO Richard Aird said completing ZBM2 batteries with Thai-made battery stacks was an important milestone. “Our first requirement of the new factory is quality components, which it is now producing in the electrode stack - the most complex and critical part of our product,” he said.

“Our pre-delivery tests have confirmed that these complete batteries, using Thai-made stacks and existing battery tank sets, perform to standard, so we are now scheduling deliveries to start supplying outstanding back orders.”
