Press Release: Lithium Australia

Perth-based Lithium Australia has produced refined lithium phosphate from spent lithium-ion batteries and is now focusing on the production of lithium-ferro-phosphate cathode powder as part of its continued lithium recycling strategy

Lithium Australia has hit another milestone on its road toward recycling lithium-ion batteries with the successful production of lithium phosphate from mixed metal dust derived from waste battery electrodes.

Additionally, the company was also able to recover nickel and cobalt in a concentrate suitable as a feed for commercial refining.

The company is currently in the process of producing lithium-ferro-phosphate cathode powder from lithium phosphate powder refined using its proprietary precipitation and refining technology.

The cathode powder will be used to produce coin cells to test the performance of recycled lithium.

“Currently, few recycling operations around the world can recover lithium from lithium-ion batteries,” said Lithium Australia managing director Adrian Griffin. “Lithium Australia’s process has the potential to not only improve the sustainability of lithium-ion batteries but also ease future supply constraints that may prove problematic to the industry.”

The mixed metal dust was supplied by Victorian battery recycling company, Envirostream, which generates product by shredding batteries and separating the components for reuse.

Lithium Australia has a 14.29% stake in Envirostream, which currently operates Australia’s only facility for shredding lithium-ion batteries.

The capability to recycle lithium and other metals would prevent lithium-ion batteries from being consigned to landfills, a major issue in Australia where just 2% of batteries are recycled, according to federal scientific research outfit, CSIRO.

Successful recycling of lithium-ion batteries will allow Lithium Australia to effectively ‘close the loop’ for energy metals by capturing value from a rapidly growing waste stream.

E-Waste World Conference & Expo will take place from Thursday 14 November to Friday 15 November at the Kap Europa, Frankfurt Messe, Germany. To register for this highly focused, solutions-driven event, please click here. For sponsorship and exhibition opportunities, please email
