3DC unveiled a 3D graphene nanomaterial at CES 2026 designed to improve fast charging, power output, and battery cycle life.
At CES 2026, Japanese startup 3DC is presenting a new three-dimensional graphene nanomaterial designed to improve fast-charging and high-power battery performance.The material, called Graphene MesoSponge , uses a porous, nanoscale structure that allows electrons to move more freely inside battery electrodes.
Unlike flat graphene sheets, GMS forms a connected internal network, which 3DC says reduces resistance and improves charging efficiency.Founded in 2022, 3DC is commercialising research that began nearly a decade earlier at Tohoku University.The company is backed by Open Innovation funding from Hyundai and is currently operating at pilot scale while working with global battery manufacturers.Graphene built in 3DGMS stands apart from conventional graphene because of its structure. It forms a hollow, sponge-like network with walls only one atom thick. The company controls pore size, layer count, and overall shape during manufacturing.“We produce a three-dimensional graphene nanomaterial,” Kazushi Misawa from 3DC told Interesting Engineering.“It is a very unique type of nanomaterial.”The nanoscale structure allows electrons to travel through interconnected pathways rather than across flat surfaces.Graphene MesoSponge designed by 3DC.

The porous network allows electrons to move faster, which supports higher charging speeds and power output.“Electrons can pass through the network inside this porous structure,” Misawa said. “Because of that, electrons move faster inside the battery.”The company says this design also helps reduce degradation over time. Improved electron transport lowers stress on battery materials during repeated charging cycles, which can extend usable life.“This improves fast-charging performance and high-power performance,” Misawa said. “It also helps improve cycle life.”Battery applications remain 3DC’s primary focus. The company is already supplying pilot-scale samples to manufacturers worldwide.From pilot to production3DC is currently testing its material with major battery companies. Several global manufacturers are evaluating GMS for use in lithium-ion and next-generation battery designs.“We have already sent samples to many battery manufacturers,” Misawa said.“Most major battery companies are currently testing our samples.”The startup plans to scale up production soon. It aims to move from pilot manufacturing to full mass production in 2026.Beyond batteries, 3DC says it can tailor the material’s structure for other uses, including semiconductor thermal management.Branched structures support ion transport, while denser forms improve heat dissipation.3DC holds more than 50 patents related to the material and its manufacturing process.The company says that combination of structure control and scalability makes GMS difficult to replicate.“This material is one of a kind,” Misawa said. “Only we can produce this structure.”For ongoing news, in-depth reporting, and key developments from CES 2026, read the IE team’s coverage here.
