Redflow board pleased by Thai factory progress

The Redflow Limited board has commended the successful commissioning of the company’s new factory in Thailand after visiting the facility this month.

During the two-day inspection, Redflow directors saw factory staff fully assemble two ZBM2 zinc-bromine flow batteries which are now undergoing post-production acceptance testing.

Redflow Chairman Brett Johnson said the board had been pleased by progress at the factory. “We are impressed by the commitment of the on-site team to producing high-quality components,” he said.

First Redflow Thai-stack batteries ready for customers

Redflow Limited has completed the first ZBM2 batteries using battery stacks made by its new Thailand factory, which are now ready for shipment to customers.

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 produces first battery stacks in Thailand

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.

Redflow makes first battery components in Thailand

Redflow Limited has successfully started manufacturing core components for its zinc-bromine flow batteries at its new production facility in Thailand.

During the past week, Redflow began producing electrode inserts made of HDPE (High-Density Polyethylene) plastic on the production line at the factory in the Hemaraj industrial estate, south-east of Bangkok. The electrode inserts – produced from custom-made highly conductive plastic – use a bipolar design to enable a zinc-plating reaction on one side and a bromine reaction on the other.

Redflow CEO Richard Aird said production of the first components was going according to plan, as outlined last month at the company’s Annual General Meeting in Brisbane. “We remain on track to produce full battery stacks from our Thai factory next month,” he said.

Redflow aims for 250 batteries/month from Thailand

Australian battery company Redflow Limited aims to produce as many as 3000 batteries a year from its new Thai factory, which it is currently fitting out, reports Redflow Chairman Brett Johnson.

In a letter to shareholders, Mr Johnson said that once the Thai facility was fully operational, it would have the capacity to manufacture as many as 250 batteries a month. “I am confident that once our new factory is producing quality batteries, Redflow will be able to demonstrate that it has a unique and viable product with real benefits for many energy storage applications,” he said.

Redflow starts battery line install in Thai factory

Australian battery company Redflow Limited has started installing battery production equipment at its new factory in Thailand, putting it on track to commence initial operation by the end of this year.

Through its Thai subsidiary, Redflow has signed a three-year lease on the 1500-square-metre 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.

Redflow has also obtained all required Thai regulatory approvals to operate its factory within the free trade zone. This week Redflow has sent an engineering team from its Brisbane office to Thailand to assist its manufacturing partner MPTS with installing and commissioning the equipment.

Redflow chooses Thailand for battery factory

Redflow Limited has today announced it has established a company in Thailand to manage the production of its zinc-bromine flow batteries in South East Asia. This follows the ASX-listed company’s announcement in May of its decision to move battery manufacturing from North America to South East Asia, to be closer to its most lucrative markets, in Australia, Oceania and southern Africa, and to reduce production costs.

In a statement to the ASX this morning, Redflow reported that it has established Redflow (Thailand) Limited, which is negotiating a lease on premises in a Thai free trade zone. It is also seeking Thai licensing and regulatory approvals. As well as its location, close to Redflow’s supply chain and marketplaces, Thailand offers good manufacturing expertise, competitive logistics, an attractive labour cost and effective tax treatment for international manufacturers within its free trade zone structure.

Redflow CEO Simon Hackett said the final North American production batch of ZBM2 batteries was now in transit to Australia. “I’m pleased to report that our stack manufacturing equipment from North America has arrived in Thailand ahead of schedule,” he said.

Redflow cashes up to target battery demand areas

Australian battery company Redflow Limited today unveiled an investment package that will raise $14.5 million to target sustainable delivery of its zinc-bromine flow batteries to high demand areas such as telecommunications. Redflow’s capital-raising follows its May announcement of decisions from a strategic review including:

  • Prioritising sales to supply proven demand areas including mature telecommunications / industrial / commercial, remote/off-grid power and ‘weak-grid’ market segments
  • Transitioning battery production to South East Asia at a more appropriate manufacturing site to leverage proximity to proven markets and reduce supply chain costs
  • Implementing a range of key battery cost-down projects to reduce delivered product manufacturing cost by at least 30 per cent over the next 18 months, and
  • Targeting sustainable cashflow-positive operations by the end of 2018.

Redflow has provided an Investor Presentation containing details of the outcome of its Strategic Review and consequent activities undertaken or planned by the company, plus its new manufacturing partner, Malaysian-based MPTS, a long-term supplier of a core component of Redflow’s battery stack.
