A coated, single crystal cathode material introduced by Nano One Materials provides up to 4 times improvement in longevity for lithium-ion batteries.
While conventional cathodes suffer of the expansion and contraction of the crystalline particles clusters during charging and decharging, the monocrystalline structure developed by Nano One are able to withstand those reactions. Because of the required longer firing time in the kiln which could damage the lithium nickel structures, the process includes the appliance of protective coatings. The technology especially targets lithium nickelt manganese cobalt oxide (NMC811) and is patent pending.
“We are focused on optimizing this [material] 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,” says Dr. Stephen Campbell, Chief Technology Officer of Nano One Materials.
