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

This abstract first appeared for US patent application 20240097117 titled 'COMPOSITE CATHODE ACTIVE MATERIAL, CATHODE AND LITHIUM BATTERY EACH CONTAINING COMPOSITE CATHODE ACTIVE MATERIAL, AND PREPARATION METHOD OF CATHODE ACTIVE MATERIAL

Simplified Explanation

The composite cathode active material described in the patent application includes a core with primary particles and a shell, where the primary particles contain a first lithium transition metal oxide comprising nickel, and the shell consists of a first layer and a second layer. The first layer contains a first metal composition, while the second layer contains a second composition with phosphorus. The first metal in the first layer includes one or more metals, other than nickel, from groups 2 to 5 and groups 7 to 15 of the periodic table of elements.
