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 18512735 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 consists of a core with primary particles and a shell. The primary particles contain a first lithium transition metal oxide with nickel, while the shell has a first layer with a first metal composition and a second layer with a phosphorus-containing second composition. The first metal in the first layer includes metals from Groups 2 to 5 and Groups 7 to 15 of the Periodic Table of Elements.
