What Sixonia does

Sixonia GmbH is a Dresden-based materials company that produces eGraphene, a functionalized few-layer bulk graphene sold to industrial customers in the battery and functional coatings sectors. The company applies a patented electrochemical exfoliation process with in-situ functionalization (EP3732315B1 and EP4530375A1) to separate graphite into large, thin graphene flakes while introducing functional groups that prevent restacking and enable stable, surfactant-free dispersions in water, NMP, DMF, DMSO, and other solvents. The result is a material that combines world-record film conductivity (up to 140,000 S/m) with drop-in processability at low loadings, addressing the traditional trade-off between conductivity and manufacturability in graphene additives.

The company's commercial offering spans three formulations — dispersions, pastes, and dry agglomerates — and targets two end markets: battery manufacturers (conductive additives for LFP, NMC, sodium, sulfur, and LNMO cathodes; silicon, silicon-graphite, graphite, SCC, and LTO anodes; CC primer coatings; and interface coatings for solid-state and Li-metal systems) and functional coatings producers (anti-corrosion, moisture barrier, EMI/Radar shielding, thermal management, fire/heat protection, conductive, and epoxy-reinforcement systems). Revenue is generated through direct enterprise sales of materials and paid sample validation programs, with custom functionalizations offered for selected projects after technical deep-dives.

The company operates a 300 kg/a pilot production line in Dresden and is scaling toward 2-10 t/a by 2027/28 and 100-1000 t/a by 2029+ via modular, automated containerized production units designed for local supply near customer sites. Sixonia holds 10+ global patents, has accumulated ten years of R&D, and is supported by partnerships with TU Dresden, Fraunhofer Institute, the European Graphene Flagship, ChemStars, and TUMVL, alongside EU co-funding. Total disclosed funding is €2.6m, headcount is 1-10, and the company has signed its first Offtake Agreement.

Core offering

Sixonia manufactures and sells eGraphene, a functionalized few-layer bulk graphene material produced via a patented aqueous electrochemical exfoliation process with in-situ functionalization. The material is supplied in multiple formulations (dispersions, pastes, dry agglomerates) and serves two primary application domains: battery materials — conductive additives for cathodes/anodes, current collector primer coatings, and interface coatings for next-generation cells; and functional coatings — anti-corrosion, moisture barrier, EMI/Radar shielding, thermal management, fire/heat-protective, conductive, and epoxy/adhesive reinforcement systems.

Product overview

Sixonia offers eGraphene as its core product platform - a functionalized few-layer graphene material produced via patented electrochemical exfoliation with in-situ functionalization. The product portfolio centers on eGraphene, which is available in multiple formulations (dispersions, pastes, dry agglomerates) and serves two primary application domains: Battery Materials (conductive additives, CC primer coatings, and interface coatings) and Functional Coatings (anti-corrosion, moisture barriers, EMI shielding, thermal management, fire protection, and mechanical reinforcement). eGraphene achieves world-record conductivity of up to 140,000 S/m while enabling surfactant-free processing.
