A coated cathode material for lithium-ion batteries is disclosed. Methods and systems are further provided for applying a coating to an active cathode material for use in a lithium-ion battery. In one example, the coated cathode material may include a high-nickel content active cathode material, such as lithium nickel manganese cobalt oxide or lithium nickel aluminum cobalt oxide, coated with a coating including one or more high energy density active materials, such as lithium vanadium fluorophosphate and/or a lithium iron manganese phosphate compound. In some examples, the high-nickel content active cathode material may include greater than or equal to 60% nickel content.
