The International Bureau of the World Intellectual Property Organisation has published two patent applications from Lithium Australia.
The applications detail Lithium Australia’s lithium phosphate recovery process, which extracts the material from lithium-bearing silicates and solutions.
According to a Lithium Australia statement, the patents seek to protect intellectual property derived from the company’s research and development activities.
“Intellectual property is managed by way of formal patent processes to retain ‘know-how’ as trade secrets, with the support of specialist legal practitioners,” the statement reads.
Lithium Australia Managing Director Adrian Griffin said the technology improves the sustainability of, and reduces the environmental impacts associated with, the manufacture, use and disposal of lithium-ion batteries.
“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,” Mr Griffin said.
“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.”
