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.”
