Samsung patents new solid electrolyte materials for batteries

Patent drawing from the official filing.

Samsung has filed a patent for specific solid-state electrolyte materials made from lithium, scandium, and bromine. These materials are designed to conduct ions effectively within a battery, which is a key step toward developing solid-state batteries that may offer higher energy density and safety compared to traditional liquid electrolytes.

Why it mattersSolid-state batteries are a major focus for the future of electric vehicles and electronics, as they promise longer ranges and faster charging, making this a significant step in battery technology development.

In the filing’s own words

Electrolyte materials having the formulas Li 3 ScBr 6, Li 5 ScBr 8, or Li 4 ScBr 7 are provided, wherein the electrolyte material crystallizes in a space group selected from the group consisting of P-31c, P312, P-31m, P1, C2/m, and R3c. A solid-state battery comprising Li 3 ScBr 6, Li 5 ScBr 8, or Li 4 ScBr 7 electrolyte materials is provided. Methods for making Li 3 ScBr 6, Li 5 ScBr 8, and Li 4 ScBr 7 electrolyte materials are also provided.

What exactly they claim (claim 1)

1. An electrolyte material according to the formula Li 3 ScBr 6, the formula Li 5 ScBr 8, or the formula Li 4 ScBr 7 wherein the electrolyte material crystallizes in a space group selected from the group consisting of P-31c, P312, P-31m, P1, C2/m, and R3c.
