SOLID-STATE ELECTROLYTE MATERIALS FOR ALL-SOLID-STATE BATTERIES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17824584 titled 'SOLID-STATE ELECTROLYTE MATERIALS FOR ALL-SOLID-STATE BATTERIES

Simplified Explanation

The patent application describes an all-solid-state electrochemical battery with a positive electrode, a negative electrode, and a solid-state electrolyte layer separating them.

  • The positive electrode contains a positive electroactive material and a solid-state electrolyte material.
  • The solid-state electrolyte material is represented by LiAB, where A can be yttrium, indium, scandium, erbium, or combinations, and B can be chloride, bromide, ClBr (where 0<x<1), or combinations.
  • In some variations, the positive electroactive material includes a nickel-rich material, and the solid-state electrolyte layer includes a sulfide-based electrolyte material.


Original Abstract Submitted

The present disclosure provides an all-solid-state electrochemical battery that includes a positive electrode, a negative electrode, and a solid-state electrolyte layer disposed between and separating the positive electrode and the negative electrode. The positive electrode includes a positive electroactive material and a solid-state electrolyte material. The solid-state electrolyte material may be represented by LiAB, where A is selected from the group consisting of: yttrium (Y), indium (In), scandium (Sc), erbium (Er), and combinations thereof, and B is selected from the group consisting of: chloride (Cl), bromide (Br), ClBr(where 0<x<1), and combinations thereof. In certain variations, the positive electroactive material includes a nickel-rich electroactive material, and the solid state electrolyte layer includes a sulfide-based electrolyte material. The solid-state electrolyte layer can also include the solid-state electrolyte material may be represented by LiAB.
