COMPOSITE CATHODE, METHOD OF PREPARING THE SAME, AND SECONDARY BATTERY INCLUDING THE COMPOSITE CATHODE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17897484 titled 'COMPOSITE CATHODE, METHOD OF PREPARING THE SAME, AND SECONDARY BATTERY INCLUDING THE COMPOSITE CATHODE

Simplified Explanation

The abstract describes a composite cathode for use in batteries. The cathode includes a current collector and a cathode active material layer. The cathode active material layer consists of a crystalline phosphate solid electrolyte, a crystalline phosphate cathode active material with high electrical conductivity, and an interphase between the two materials.

  • The composite cathode is designed for use in batteries.
  • It includes a current collector and a cathode active material layer.
  • The cathode active material layer consists of a crystalline phosphate solid electrolyte.
  • It also includes a crystalline phosphate cathode active material with significantly higher electrical conductivity than the solid electrolyte.
  • An interphase is present between the solid electrolyte and the cathode active material.

Potential applications of this technology:

  • This composite cathode can be used in various types of batteries, such as lithium-ion batteries.
  • It can improve the performance and efficiency of batteries by enhancing the electrical conductivity of the cathode active material.
  • The composite cathode can be used in electric vehicles, portable electronics, and renewable energy storage systems.

Problems solved by this technology:

  • Traditional cathode materials may have limited electrical conductivity, which can hinder the performance of batteries.
  • The composite cathode addresses this issue by incorporating a cathode active material with significantly higher electrical conductivity.

Benefits of this technology:

  • The composite cathode improves the overall performance and efficiency of batteries.
  • It allows for faster charging and discharging of batteries.
  • The enhanced electrical conductivity of the cathode active material leads to improved power output and longer battery life.


Original Abstract Submitted

A composite cathode, including: a cathode current collector; and a cathode active material layer on the cathode current collector. The cathode active material layer includes: a crystalline phosphate solid electrolyte; a crystalline phosphate cathode active material having an electrical conductivity about 10 times to about 10 times greater than an electrical conductivity of the crystalline phosphate solid electrolyte; and an interphase between the crystalline phosphate solid electrolyte and the crystalline phosphate cathode active material.
