CSIRO scientist tells ABC Radio that zinc-bromine flow batteries are ‘potentially considerably cheaper’ than lithium

CSIRO Principal Research Scientist Dr Adam Best has told ABC Radio that zinc-bromine flow batteries are ‘potentially considerably cheaper’ than lithium batteries because they don’t require the “critical minerals” used in a lithium-ion battery.

Dr Best, who is currently on secondment from CSIRO to Energy Renaissance as a Research and Development Advisor, has led a CSIRO team for lithium battery development, including a focus on advanced electrolytes, to support the development of an Australian battery industry

In an interview with ABC Radio’s Geraldine Doogue, Dr Best described zinc-bromine flow batteries as “an Australian invention” that uses “a completely different type of chemistry”.  “A company called Redflow actually makes these batteries,” he said.

“They have a very different type of electrolyte and they basically use pumped fluids to do the energy storage activity. So it’s very much a different style of battery, much bigger than you would see currently in a lithium-ion system, but potentially considerably cheaper because you don’t use a lot of the critical minerals that a lithium-ion battery uses.”
