  • CATHODE COATING
    Publication number: 20230343954
    Abstract: Provided herein are new processes for coating a cathode active material with a solution that includes lithium and optionally boron. Also provided herein are new cathode active materials having a coating which includes lithium carbonate and lithium borate. Also provided herein are new cathode active materials having one or two coating thereupon which increase the stability of the cathode active material at high voltage. In some examples, one of the coatings is LixZryOz, wherein 0?x?1.6, 0.2?y?1.0, and 2?z?1.2; LixZryOz, wherein 0.6?x?1.5, 0.5?y?1.4, and 2.0?z?3.7; or LixZry(PO4)z, wherein 0.05?x?1.5, 1?y?3, and 2.0?z?4.0.
