Redflow produces first battery electrode stacks from Thai factory

Australian battery company Redflow has achieved a second 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 – a process that can sustain 10kWh of energy storage capacity throughout the battery’s operating life.

Redflow produced its first battery components from the factory last month.

The factory has set up and qualified its battery stack machines and processes, optimising them for Thai environmental conditions.

Redflow managing director and CEO Richard Aird said assembly of the battery stacks in Thailand had gone according to plan.

“The manufacturing team is very happy with the consistent quality and acceptable yield metrics of the stack line,” he said.

Achieving this battery stack milestone means Redflow’s Thai factory is on track to progressively validate quality components and sub-assemblies so it can produce complete batteries by June 2018.

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.
