Nano One Materials Corp (CVE:NNO) (OTCMKTS:NNOMF) is advancing the company’s latest lithium nickel manganese cobalt (NMC) innovations aimed at making high-energy lithium ion batteries safer and more durable.
In a statement on Wednesday, Dr Stephen Campbell, the company’s chief technology officer said Nano’s latest innovations provide durability and safety to NMC cathodes by protecting them from the stresses of repeated charging.
“We are able to form protective coatings on individual particles and this is clearly differentiated from others who are developing coatings on larger clusters of particles. The stresses of repeated charging cause large coated clusters to break apart, leaving individual particles on the inside exposed to side reactions. Our technology is particularly relevant to high-energy nickel-rich NMC batteries because it provides added protection," he added.

The automotive battery industry is actively pursuing higher nickel content in lithium ion batteries because it can boost energy density and thereby extend vehicle range while reducing the cobalt content.
However, the trade-off is an increased risk to a battery’s stability, durability and safety. To mitigate these problems, Nano One’s technology seeks to protect each nanoparticle rather than larger clusters.
The Vancouver-based company’s latest innovations make NMC materials with a protective coating in fewer steps and form individual nanoparticles that are designed to resist cracking and withstand the rigors of repeated charging.
Nano One said it is able to control the formation of its patented NMC materials using innovative manufacturing technologies, which are also protected by patents in the US, Canada, Taiwan, China, Japan and Korea.
"These are novel materials and coatings that have the potential to enable stable, low cost, fast charging and energy dense cathodes ideal for electric vehicles and other high-energy density applications,” Dr Campbell said.
“These innovations differentiate Nano One and add considerable value to the development activities we now have underway with our automotive and battery materials partners."
