Samsung patents new solid electrolyte materials for batteries

Patent drawing from the official filing.

Samsung has filed a patent application for two specific solid-state materials, Li3ScI6 and Li5ScI8, designed to act as electrolytes in batteries. The filing describes how these materials move lithium ions efficiently and outlines methods for manufacturing them in specific crystal structures.

Why it mattersThis is interesting for battery enthusiasts because solid-state electrolytes are a key step toward safer, higher-capacity batteries, though this is just one of many materials being tested.

In the filing’s own words

Electrolyte materials having the formulas Li 3 ScI 6 or Li 5 ScI 8 are provided, wherein the electrolyte material crystallizes in a space group selected from the group consisting of R3m, Cmmm, and C2/m. A solid-state battery comprising Li 3 ScI 6 or Li 5 ScI 8 electrolyte materials is provided. Methods for making Li 3 ScI 6 or Li 5 ScI 8 electrolyte material are also provided.

What exactly they claim (claim 1)

1. An electrolyte material according to the formula Li 3 ScI 6 or the formula Li 5 ScI 8, wherein the electrolyte material crystallizes in a space group selected from the group consisting of R3m, Cmmm, and C2/m.
