Lithium Australia Seeks to Strengthen Battery Recycling IP Protection

THE BOURSE WHISPERER: Lithium Australia (ASX: LIT) revealed it has filed two International Patent Applications with the Australia Patent Office.

Lithium Australia made the submissions under the Patent Cooperation Treaty (PCT), which relate to the company’s 90 per cent-owned subsidiary company, Envirostream Australia Pty Ltd’s selective separation of metal values from recycled lithium-ion batteries and recovery of electrode materials.

The first of the PCT applications: ‘Process for recovering values from batteries’ covers a size-selective process for recovering electrode material from lithium-ion batteries, including as a mixed metal material (mixed metal dust, ‘MMD’) that comprises both cathode and anode powders.

The second: ‘Process for recovering values from process liquors’ describes processes for the selective recovery of mixed metal sulphates (such as a mixed cobalt-nickel sulphate) from a metal sulphate process liquor following leaching of mixed metal material (MMD) recovered from lithium-ion batteries.

“The Lithium Australia group is acutely aware of its environmental footprint and that of the society within which we live and operate,” Lithium Australia managing director Adrian Griffin said in the company’s ASX announcement.

“We can no longer afford to discard any products to landfill, let alone those that have a high embedded energy footprint, contain critical materials, or – in the case of lithium-ion batteries – both.

“We have developed unique processes to deal with battery waste and invite like-minded industry participants to work with us in improving the sustainability of our consumer-based society.”
