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 18474350 titled 'COMPOSITE CATHODE ACTIVE MATERIAL, CATHODE AND LITHIUM BATTERY INCLUDING THE SAME, AND METHOD OF PREPARING THE COMPOSITE CATHODE ACTIVE MATERIAL

Simplified Explanation

The patent application describes a composite cathode active material for use in a lithium battery. The composite material consists of a core made up of primary particles, a grain boundary between adjacent primary particles, and a shell surrounding the core. The core is composed of a nickel-containing lithium transition metal oxide with a layered crystal structure, while the shell is made of a second lithium transition metal oxide with a spinel crystal structure. The grain boundary contains a first composition with a spinel crystal structure.

  • The composite cathode active material consists of a core, a grain boundary, and a shell.
  • The core is made of primary particles containing a nickel-containing lithium transition metal oxide with a layered crystal structure.
  • The shell surrounding the core is composed of a second lithium transition metal oxide with a spinel crystal structure.
  • The grain boundary between adjacent primary particles contains a first composition with a spinel crystal structure.

Potential applications of this technology:

  • Lithium batteries: The composite cathode active material can be used in lithium batteries to improve their performance and energy density.

Problems solved by this technology:

  • Enhanced performance: The composite cathode active material with a core-shell structure and grain boundary improves the performance and stability of lithium batteries.
  • Higher energy density: The use of the composite cathode active material allows for higher energy density in lithium batteries, leading to longer-lasting and more efficient power sources.

Benefits of this technology:

  • Improved battery performance: The composite cathode active material enhances the overall performance and stability of lithium batteries, leading to longer battery life and improved efficiency.
  • Higher energy density: The use of the composite cathode active material allows for higher energy density in lithium batteries, enabling longer-lasting power sources.
  • Enhanced stability: The core-shell structure and grain boundary of the composite cathode active material contribute to the stability and reliability of lithium batteries.
