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.
