Solivis said on Wednesday it has completed a 23 billion won Series C funding round to advance sulfide-based solid electrolyte technology and expand production capacity.

Openwater Investment and Seulgi Asset Management took part in the round. Solivis has raised a cumulative 65.2 billion won since it was founded in 2020. Along with the funding, it was also selected for the Ministry of SMEs and Startups’ 2026 support programmes, “Super Gap Global Deep Techs” and “Unicorn Bridge.”

The global all-solid-state battery market is expected to surge to 1.2 trillion won in 2026 from 210 billion won in 2023. Sulfide-based solid electrolytes are regarded as a key material for next-generation batteries due to high ionic conductivity, and competition is intensifying among major global automakers and battery makers to adopt them.

Solivis, founded in 2020, is a specialised all-solid-state materials company with about 150 patents. Through its “third-generation wet synthesis mass-production platform”, it achieves what it called industry-leading ionic conductivity and is mass-producing at an annual scale of 36 tonnes at its Hoengseong plant in Gangwon Province.

Shin Dong-wook (신동욱), Solivis CEO, said, "This achievement shows recognition of both our proprietary technology and the growth potential of the global market." He said, "With the funds secured, we will maximise mass-production competitiveness and lead the global all-solid-state battery materials market." He added, "As the commercialisation of all-solid-state batteries draws closer, the quality stability and mass-production capability of solid electrolytes are emerging as key factors." He said, "We will respond quickly to market demand based on our differentiated technology."
