Samsung patents solid salt materials for better battery ion flow

Patent drawing from the official filing.

Samsung describes solid electrolyte materials made from lithium, calcium, and chlorine that help ions move through a battery. The filing explains how these specific crystal structures can be created and used in solid-state batteries.

Why it mattersThis is interesting because solid electrolytes are a key part of developing safer, higher-capacity batteries for electric cars and devices.

In the filing’s own words

Electrolyte materials having the formulas Li 2 CaCl 4 or Li 3 Ca 2 Cl 7 are provided, wherein the electrolyte material crystallizes in a space group selected from the group consisting of Cm, Imma, Cmmm, and P 1. A solid-state battery comprising Li 2 CaCl 4 or Li 3 Ca 2 Cl 7 electrolyte materials is provided. Methods for making Li 2 CaCl 4 and Li 3 Ca 2 Cl 7 electrolyte materials are also provided.

What exactly they claim (claim 1)

1. An electrolyte material according to the formula Li 2 CaCl 4 or the formula Li 3 Ca 2 Cl 7, wherein the electrolyte material crystallizes in a space group selected from the group consisting of Cm, Imma, Cmmm, and P 1.
