SOLID ELECTROLYTE MATERIAL AND BATTERY USING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18418292 titled 'SOLID ELECTROLYTE MATERIAL AND BATTERY USING SAME

Simplified Explanation

The patent application describes a solid electrolyte material with specific compositions of cations and anions, forming a unique anion framework structure.

  • Cation A is an ion conductive species, selected from alkali and alkaline earth metal elements.
  • Cation B is not an ion conductive species, selected from alkali and alkaline earth metal elements other than cation A, transition metal elements, and Groups 13 to 16 elements.
  • Anions X and Z are each independently selected from the Groups 14 to 17 elements, forming an anion framework with a MgCu-type structure.
  • The molar ratio of anion X to anion Z is between 1 and 4.

Original Abstract Submitted

A solid electrolyte material comprises a cation A that is an ion conductive species, a cation B that is not an ion conductive species, an anion X, and an anion Z. The cation A is at least one element selected from the group consisting of alkali and alkaline earth metal elements. The cation B is at least one element selected from the group consisting of alkali and alkaline earth metal elements other than the cation A, transition metal elements, and the Groups 13 to 16 elements. The anions X and Z are each independently at least one element selected from the group consisting of the Groups 14 to 17 elements. The anions X and Z constitute an anion framework having a MgCu-type structure. The molar ratio of the anion X to the anion Z is greater than or equal to 1 and less than or equal to 4.
