Abstract
A coated cathode material including high-nickel lithium cathode and a method of producing the same by atomic layer deposition.
Claims11
A method of producing a nickel cathode material, the method comprising:
- providing a lithium precursor;
- selectively depositing an oxide, fluoride, nitride, or a combination thereof on the lithium precursor by atomic layer deposition (ALD), forming an ALD-treated lithium precursor;
- preparing a mixture of nickel metal hydroxide with the ALD-treated lithium precursor;
- calcining the prepared mixture.
