Solivis Sulfide Solid Electrolytes

Solivis is a South Korean maker of sulfide solid electrolytes for all-solid-state batteries, with its address in Hanam-si, Gyeonggi-do. A news article published in August 2026 gives the founding year as 2020.

The company supplies crystalline and amorphous sulfide electrolytes and custom products made with its proprietary wet synthesis process, which it calls a third-generation mass-production platform. Solid electrolytes replace liquid electrolytes in the cell to improve safety and energy density. Output comes from a plant in Hoengseong, Gangwon Province, rated at 36 tonnes a year.

• Sulfide electrolytes: crystalline and amorphous solid electrolyte powders.
• Wet synthesis: proprietary third-generation mass-production process.
• Custom products: electrolytes tailored to customer cell designs.
• Mass-production plant: Hoengseong site with 36 tonnes annual output.
• Patent portfolio: over 100 patents cited in a 2025 technology award.

Battery R&D teams in Vietnam could source electrolyte samples for solid-state cell prototypes. EV makers could use it in joint evaluation programs. Research institutes could use custom grades for pilot lines.

Solid electrolytes can improve cell safety versus liquid electrolytes. Crystalline and amorphous grades are available, plus custom products. The company cites more than 100 patents for customized design. A dedicated mass-production plant supports supply to battery makers.

Automakers and battery makers are racing to commercialize all-solid-state batteries, which makes sulfide electrolyte supply a bottleneck material. Vietnam EV and battery producers may seek qualified solid-electrolyte suppliers as the technology matures.
