The material operates at “high voltage” with fast rates of charge and discharge, compared to other cathode materials
Corp () (OTCMKTS:NNOMF) revealed Monday that it had been granted a Taiwanese patent relating to a lithium nickel manganese oxide (LNMO) cathode material, also known as high voltage spinel.
In a statement, the company said patent number I672852 issued for Nano One's lithium nickel manganese oxide not only boosts durability but also eliminates cobalt from the battery.
“This addresses the ethical and supply chain issues related to artisanal cobalt mining in Africa for use in lithium ion batteries,” noted the company.
"This addition to Nano One's patent portfolio is an important, low cost durability improvement to LNMO,” said Dr Stephen Campbell, chief technology officer at Nano One.
Dr Stephen Campbell also noted that the material operates at “high voltage” with fast rates of charge and discharge, compared to other cathode materials.
“Our technology treats the surface of the discrete cathode crystals and it mitigates instabilities common to spinels including LNMO and enables elevated operating temperatures that are typical in electric vehicle batteries," said Dr Campbell.
This represents the 16th patent in Nano One's intellectual portfolio which extends to the US, Canada, China, Japan, Korea and Taiwan. There are currently more than 30 patents pending.
Nano One, based in Burnaby, British Columbia, has developed patented technology for producing low-cost, high-performance battery materials and a wide range of other advanced nanostructured composites used in electric vehicles, energy storage and consumer electronics.
