Qld cathode powder process wins European patent

Qld cathode powder process wins European patent

A Lithium Australia subsidiary has been granted a European patent to produce specialist metal oxides for new battery-fuel technologies.

VSPC’s advanced cathode powders are manufactured at its pilot plant and R&D facility in Brisbane.

“VSPC has been granted a European patent for the production of complex metal-oxide nanoparticles,” Lithium Australia managing director Adrian Griffin said.

“A low-cost process, it accurately controls the chemical composition and distribution of the chemical elements within in a predetermined crystal structure.

“The resulting products can be used in many applications, among them catalysts, solid-oxide fuel cells, super conductors and lithium-ion batteries (‘LIBs’), to name but a few.

“This greatly enhances Lithium Australia’s arsenal of intellectual property and reinforces our position as a significant supplier of innovative technology to the battery industry.”

The European Patent Office has granted the VSPC patent entitled ‘Method for Producing Fine-Grained particles (EP 1 812 340 B1).

Lithium Australia said the VSPC process technology was relevant to a number of battery materials, among them metal-oxide cathode powders (e.g. lithium manganese oxide (LMO), lithium nickel manganese oxide (LMNO), lithium nickel manganese cobalt oxide (NMC)), as well as phosphate-based cathode materials like lithium ferro phosphate (‘LFP’) and lithium manganese ferro phosphate (‘LMFP’). Most other cathode-powder types can also be produced using the VSPC process.

Lithium titanate (‘LTO’), used as an anode material in long-life lithium-ion batteries, is another medium that can be manufactured using the VSPC process.

VSPC is completing a preliminary feasibility study for the production of LFP cathode material for a number of locations outside China. The results of that study are due in the March 2021 quarter.
