Claim 42:
43. A method for lithiating commercially available nickel hydroxide into a nano-crystalline lithium nickelate for use in lithium batteries as a cathode active material, the method comprising:
lithiating nickel hydroxide particles with an aqueous lithium salt slurry to produce a mixture;
removing water from the mixture to produce a dried material;
initially milling and screening the dried material until the dried material passes through a −30 to −160 micron screen;
furnacing the dried material above 700 degrees Celsius for 0.5 to 4 hours in the presence of oxygen to produce a LiNiO2 material; and
secondarily milling and screening the LiNiO2 material until the LiNiO2 material is from −30 to −70 microns to produce the nano-crystalline lithium nickelate.
