Systems and methods for coating cathode active material

Abstract

Methods are provided for coating a cathode active material particle. The method includes preparing a lithium niobate precursor solution, wherein a ratio of lithium to niobium in the lithium niobate precursor solution is determined by a surface composition of the cathode active material particles, mixing the cathode active material particles with the lithium niobate precursor solution, hydrolyzing the mixture and then heating the mixture to obtain cathode active material particles coated with amorphous lithium niobate.
