Redflow suspends deliveries after battery mode failure incidents

Australia-based flow battery provider Redflow has paused deliveries of new batteries after a number of unexpected product mode failures during remote monitoring at customer sites, according to a filing on the Australian Stock Exchange.

Deliveries will remain suspended until a second set of tests have been completed with “satisfactory results”, said the company. At present, Redflow has roughly US$1 million worth of product back-orders, with 96 batteries in stock and another 120 batteries in transit from the factory.

The company specialises in zinc-bromide flow batteries for storing and shifting renewable energy, managing peak grid load and supporting off-grid power systems and telecommunications.

Redflow said most of the identified problems were resolved by updating battery software remotely. However, the first tests of battery electrolyte samples from a batch of ten batteries indicated that they could be at risk of failure due to impurities in the electrolyte.
