Nano One Introduces a Breakthrough in Longer Lasting Lithium-Ion Cathode Materials
June 24, 2020 (Source) – Dr. Stephen Campbell, Chief Technology Officer of Nano One Materials Corp. (TSXV: NNO) (OTC Pink: NNOMF) (FSE: LBMB) is pleased to announce the development of a coated, single crystal cathode material for lithium ion batteries that is providing up to 4 times improvement in longevity. Furthermore, this technology is applicable to all of Nano One’s cathode materials but is especially relevant to lithium nickel manganese cobalt oxide (NMC811). These latest innovations are patent pending.
Figure 1: Nano One half-cell data (1C @ 25oC) shows capacity fade is 4x less for coated NMC811
(100-96% = 4% fade) than for uncoated NMC811 (100-83% = 17% fade)
“Nano One has developed a coated single nanocrystal cathode material,” explained Dr. Campbell, “Which provides protection against undesirable side reactions and the stresses of repeated charge and discharge cycling. We are focused on optimizing this for NMC811 and I am pleased to present recent results that show how protective coatings on a robust crystal structure can make cathode powders more durable and longer lasting. Increased durability is critical in enabling extended range, faster charging and even million mile batteries for electric vehicles.”
Conventional Versus Single Crystal Cathodes
Conventional cathodes consist of a dense cluster of crystalline particles (polycrystalline), made by first forming clusters of NMC precursor then milling with lithium and firing in a kiln. Protective coatings can then be formed by adding coating materials and firing again. However, the clusters expand, contract, and break apart from repeated charging, which fractures the outer coating and leaves individual crystals within the clusters exposed to deleterious side reactions.
These polycrystalline particles can be transformed into large single crystals (monocrystalline) by prolonging the firing time in the kiln. The resulting powders are less prone to cracking but excessive time in the kiln damages the lithium nickel structures, adds prohibitive process cost and requires additional steps to apply protective coatings.
In contrast, Nano One’s patented One-Pot process combines all input components – lithium, metals, additives and coatings – in a single reaction to produce a precursor that, when dried and fired, forms quickly into a single crystal cathode material simultaneously with its protective coating.

Dr. Campbell said, “By forming protective coatings on individual nanocrystals, Nano One eliminates process steps and is engineering new materials with enhanced durability for various applications including electric vehicles. These are positive results and we are optimizing the materials for third party evaluation on the path to commercializing this technology.”
