COMPOSITE CATHODE ACTIVE MATERIAL, CATHODE AND LITHIUM BATTERY EACH CONTAINING COMPOSITE CATHODE ACTIVE MATERIAL, AND METHOD OF PREPARING COMPOSITE CATHODE ACTIVE MATERIAL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240258517 titled 'COMPOSITE CATHODE ACTIVE MATERIAL, CATHODE AND LITHIUM BATTERY EACH CONTAINING COMPOSITE CATHODE ACTIVE MATERIAL, AND METHOD OF PREPARING COMPOSITE CATHODE ACTIVE MATERIAL

The abstract describes a composite cathode active material, a cathode, and a lithium battery, each containing the composite cathode active material, as well as a method of manufacturing the composite cathode active material. The composite cathode active material consists of a core with multiple primary particles and a shell surrounding the core. The primary particles contain lithium nickel transition metal oxide, while the shell is made up of a first composition with a first metal and a second composition with a second metal. The first metal belongs to groups 2, 4, 5, and 7 to 15, while the second metal is from group 3. The first composition includes a first phase, and the second composition includes a second phase that is distinct from the first phase.
