Lithium ion battery cathode manufacturer VSPC today announced it had begun production of commercial-quality lithium titanium oxide (LTO) battery anode powders.
The company, which previously manufactured lithium ferro phosphate (LFP) and lithium manganese ferro phosphate (LMFP) cathode powders, has produced the anode materials at its electro-chemistry laboratory and pilot production facility in Brisbane (pictured).
VSPC, a subsidiary of Lithium Australia, has spent 20 years and $35 million developing its technologies which have now been extended to anode powders.
Lithium Australia managing director Adrian Griffin said: “VSPC’s successful production of high-performance LTO is an Australian first, as well as a global necessity.”
He said improved anodes are essential in the development of the lithium ion battery performance levels desired for next generation of batteries.
“VSPC’s patented technologies are applicable to the production of both anode and cathode powders.
“VSPC (is) in a unique position to deliver precursors that meet more exacting performance requirements.”
Traditionally LTO is prepared via a solid-state reaction in which raw materials are calcined at high temperatures for a prolonged period.
VSPC’s technology is a slurry-based process which reduces calcination time and ensures end-product quality.
The company is now extending its research into other battery anode materials, including lithium niobium oxide and other niobium-based anode materials often used in space and defence sectors.
