Japan startup develops 3D graphene for faster-charging batteries

At CES 2026, Japanese startup 3DC unveiled its innovative three-dimensional graphene nanomaterial called Graphene MesoSponge (GMS), designed to enhance fast-charging and high-power battery performance. Unlike traditional flat graphene sheets, GMS features a porous, sponge-like nanoscale structure with interconnected pathways that allow electrons to move more freely within battery electrodes. This unique internal network reduces electrical resistance, improves conductivity without additional additives, and supports faster charging speeds and higher power output. The material also helps reduce battery degradation over time by lowering stress on electrode materials during repeated charge cycles, thereby extending battery life. Founded in 2022 and commercializing research from Tohoku University, 3DC is currently operating at pilot scale and collaborating with major global battery manufacturers who are testing GMS for lithium-ion and next-generation batteries. The company plans to scale up to full mass production in 2026. Beyond battery applications, 3DC is exploring uses of GMS in semiconductor thermal management by
