Samsung patents new solid materials to help batteries move ions faster

Patent drawing from the official filing.

Samsung describes three specific solid materials made of lithium, calcium, chlorine, and oxygen that can act as electrolytes in batteries. These materials allow lithium ions to move through them easily, which is a key requirement for solid-state battery designs.

Why it mattersDeveloping stable solid electrolytes is a major hurdle for creating safer, higher-capacity batteries for phones and cars.

In the filing’s own words

Electrolyte materials having the formulas Li 3 Ca 3 Cl 7 O, Li 5 Ca 2 Cl 7 O, and Li 5 CaCl 5 O are provided, wherein the electrolyte material crystallizes in a space group selected from the group consisting of Cm, P2_1, Pc, Pm, P3m1, P1, and Pmn2_1. A solid-state battery comprising Li 3 Ca 3 Cl 7 O, Li 5 Ca 2 Cl 7 O, or Li 5 CaCl 5 O electrolyte materials is provided. Methods for making Li 3 Ca 3 Cl 7 O, Li 5 Ca 2 Cl 7 O, and Li 5 CaCl 5 O electrolyte material are also provided.

What exactly they claim (claim 1)

1. An electrolyte material according to the formula Li 3 Ca 3 Cl 7 O, the formula Li 5 Ca 2 Cl 7 O, or the formula Li 5 CaCl 5 O wherein the electrolyte material crystallizes in a space group selected from the group consisting of Cm, P2_1, Pc, Pm, P3m1, P1, and Pmn2_1.
