3DC develops and manufactures Graphene MesoSponge® (GMS), a three-dimensional graphene material with porosity, conductivity, flexibility, and corrosion resistance intended to address trade-offs in battery performance. The company was founded in February 2022 and is headquartered at Tohoku University in Sendai, with a Kawasaki office and a pilot factory in Toki, Gifu where construction of the world’s first GMS mass-production facility has begun. Following a Series A 1st-close in August 2025 and ongoing validation work, 3DC is supplying functional conductive additive GMS to numerous domestic and international battery makers for evaluation. 3DC plans to use recent and prior funding to expand its pilot factory into a mass-production plant, establish ton-scale production processes, strengthen global supply for customer evaluations and commercialization, and expand R&D talent and overseas partnerships. The company positions partnerships with established industry players and strategic investors as key to accelerating production, supply-chain stabilization, and market adoption of GMS.
