==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.
* The core is made up of primary particles containing a nickel-containing lithium transition metal oxide with a layered crystal structure.
* The shell is 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.

Potential applications of this technology:

* Lithium batteries
* Energy storage systems
* Electric vehicles
* Portable electronic devices

Problems solved by this technology:

* Improves the performance and efficiency of lithium batteries
* Enhances the stability and cycling life of the battery
* Increases the energy density of the battery

Benefits of this technology:

* Higher energy density and capacity in lithium batteries
* Longer cycling life and improved stability
* Enhanced performance and efficiency of the battery
* Potential for smaller and lighter battery designs


==Original Abstract Submitted==

A composite cathode active material and a cathode and a lithium battery including the composite cathode active material. The composite cathode active material has a core including a plurality of primary particles including a nickel-containing first lithium transition metal oxide having a layered crystal structure; a grain boundary disposed between adjacent primary particles of the plurality of primary particles; and a shell on the core, the shell including a second lithium transition metal oxide having a spinel crystal structure, wherein the grain boundary includes a first composition having a spinel crystal structure.
