Compositionally gradient nickel-rich cathode materials and methods for the manufacture thereof

Abstract

The present invention relates to lithium rechargeable battery cathode materials. More specifically, the cathode materials are compositionally gradient nickel-rich cathode materials produced using single-source composite precursor materials containing inorganic and/or metalorganic salts of lithium, nickel, manganese, and cobalt. Methods and systems for manufacturing the cathode materials by a combined spray pyrolysis/fluidized bed process are also disclosed.
