COMPOSITE CATHODE ACTIVE MATERIAL, CATHODE AND LITHIUM BATTERY INCLUDING THE SAME, AND METHOD OF PREPARING THE COMPOSITE CATHODE ACTIVE MATERIAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18089725 titled 'COMPOSITE CATHODE ACTIVE MATERIAL, CATHODE AND LITHIUM BATTERY INCLUDING THE SAME, AND METHOD OF PREPARING THE COMPOSITE CATHODE ACTIVE MATERIAL
Simplified Explanation
The abstract describes a composite cathode active material and its application in a lithium battery. The composite material consists of a core made up of primary particles containing a nickel-containing lithium transition metal oxide with a layered crystal structure. The core is surrounded by a shell made of a second lithium transition metal oxide with a spinel crystal structure. The core and shell are separated by a grain boundary, which also contains a spinel crystal structure.
- The composite cathode active material consists of a core and a shell.
