Queensland battery company Redflow has achieved a manufacturing milestone by successfully producing the first battery electrode stacks from its new factory in Thailand.
The battery stack is a critical part of the Redflow ZBM2 zinc-bromine flow battery, containing electrodes that charge and discharge the battery by “plating” and “deplating” zinc on a membrane.
This is a process that can sustain 10kW/h of energy storage capacity throughout the battery’s operating life.
Redflow produced its first battery components from the factory last month.
“The manufacturing team is very happy with the consistent quality and acceptable yield metrics of the stack line,” said Redflow’s managing director and CEO Richard Aird.
Achieving this battery stack milestone would mean that Redflow’s Thai factory is on tract to progressively validate quality components and sub-assemblies so it can produce complete batteries by June this year
Redflow last year decided to relocate its battery manufacturing from North America to Thailand, to be closer to its most lucrative markets in Australia, Oceania and southern Africa, and to reduce production costs.
The company’s Thai subsidiary has signed a three-year lease on the 1,500sqm building at the Hemaraj Chonburi Industrial Estate, part of the IEAT free trade zone, 110km southeast of Bangkok and 25km from the Laem Chabang deep-sea container port.
