Lithium Australia Patent Applications Published by WIPO

THE BOURSE WHISPERER: Lithium Australia has had two patent applications published by The International Bureau of the World Intellectual Property Organisation (WIPO).

The Lithium Australia patent applications are for the recovery of lithium phosphate from lithium-bearing silicates and solutions.

The company explained that publication is an important step towards obtaining a patent grant, which provides legal protection in international jurisdictions.

Production of lithium phosphate is a unit process common to Lithium Australia’s SiLeach® and LieNA® technologies, which potentially reduce the number of processing steps to produce battery cathode powders.

“The company has succeeded in developing technologies that improve the sustainability of, and reduce the environmental impacts associated with, the manufacture, use and disposal of lithium-ion batteries,” Lithium Australia managing director Adrian Griffin said in the company’s announcement to the Australian Securities Exchange.

“Importantly, these technologies can facilitate vertical integration within the battery supply chain, potentially reducing the number of process steps involved and lowering costs for consumers.

“The ability to integrate metal recovery from lithium-ion batteries and regenerate cathode materials represents a major advance for the battery industry as a whole.”

Lithium Australia has developed innovative processes for the recovery of lithium chemicals from lithium-bearing silicates and micas.

The company’s efforts have resulted in unit process enhancements that optimise the recovery of lithium from lowtenor solutions, while managing water-balance challenges, to produce lithium phosphate of a high quality.

The unit processes involved are the subject of the above-mentioned patent applications.

Lithium phosphate produced by way of the company’s proprietary processes meets the specification necessary for its use as feedstock in the production of lithium-ferrophosphate (LFP), a cathode precursor material in the manufacture of batteries for energy-storage system and transport applications.
