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.
Mossel Bay Municipality in the Southern Cape province of South Africa has eliminated the carbon footprint of its Technical Services Department buildings by deploying ZBM2 batteries from Redflow.
Installed in late 2016, the four 10 kilowatt-hour (kWh) zinc-bromine flow batteries have enabled the ageing offices to become net exporters of electricity to the power grid through the intelligent storage of energy harvested from 114 rooftop photovoltaic solar panels.
Mossel Bay Municipality Electricity and Mechanical Department Senior Manager Charles Geldenhuys said the Redflow energy storage system had exceeded expectations. “We are using more energy now than before the system was implemented,” he said.
Australian battery company Redflow Limited 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 10 kilowatt-hours of energy storage capacity throughout the battery’s operating life. Redflow produced its first battery components from the factory last month.
ASX-listed Redflow (ASX: RFX) reports that the factory has set up and qualified its battery stack machines and processes, optimising them for Thai environmental conditions.
Redflow Limited 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.
