Solivis

It produces and supplies both crystalline and amorphous sulfide solid electrolytes and uses its own wet synthesis process to make products to customer specifications. Solid electrolytes carry ions between the cathode and anode in place of a liquid, which the company says removes the risk of explosion and conducts better than liquid electrolytes at low and high temperatures. Solivis holds about 100 patents, is based in Hanam, Gyeonggi Province, and recently closed a Series C funding round.

The 2025 Battery Report lists Solivis among solid-state battery players in Asia-Pacific, in its sulphide electrolyte group.
