Australian battery company Redflow Limited (ASX: RFX) has today received in Australia the first battery electrode stacks made by its new Thailand facility.
The battery stack is the critical part of the Redflow ZBM2 zinc-bromine flow battery, containing electrodes that charge the battery by “plating” zinc on a membrane and then discharge it by reversing that process, which can sustain 10 kilowatt-hours of energy storage capacity for the battery’s operating life.
At Redflow’s Brisbane headquarters, the Thai-made battery stacks will be installed on ZBM2 battery tank sets (without stacks) which were manufactured last year at the former factory in North America.
Redflow Chairman Brett Johnson said these complete batteries would be tested and then supplied to customers to meet existing orders. “As we manufacture stacks for these approximately 200 tank sets, we will progressively validate high quality components and sub-assemblies at our factory,” he said.
“We aim to produce fully tested new batteries ‘end-to-end’ in our Thai production line prior to June this year. As I noted at our AGM, once we achieve this milestone, we will be able to ramp-up production in Thailand in line with customer demand. Once fully operational and orders warrant it, the manufacturing line should be able to manufacture up to 250 complete batteries a month.
“Should demand increase beyond that volume, the capital cost involved to establish a second manufacturing line is not problematic.”
Redflow’s progressive commissioning of production from its factory in Thailand is the latest step in a strategic redirection announced last year that aims to build high-quality zinc-bromine flow batteries closer to proven markets for the company’s products. Since then, Redflow has:
Mr Johnson said achieving its commitments was a major part of Redflow’s agenda for success in 2018. “The Board and management are confident that we will be producing well-made and reliable Redflow batteries in substantial numbers during the second half of 2018,” he said.
