SPRAY-DRY COATING OF ELECTROACTIVE PARTICLES

Systems, methods, and devices for producing coated electroactive-material particles are described. The coated electroactive-material particles may be produced by a spray-dry process including atomizing a non-aqueous solution that includes lithium niobium ethoxide and pristine cathode active material particles to produce an atomized solution, introducing the atomized solution into a drying chamber, and drying the atomized solution to produce lithium niobium oxide coated cathode active material particles. The atomizing is performed via an atomizer. The drying chamber has a gas flow to carry the atomized solution therethrough. The drying is performed via the gas flow within the drying chamber.
