Meet us in Stuttgart at The Battery Show Europe 2026 (11.06.2026)
More eventsIntroducing a functionalized, few-layer bulk Graphene combining world-record conductivity, drop-in formulations without surfactants, and low cost at scale.
Graphene has long promised exceptional performance, but most materials still force a trade-off: chemical routes often damage conductivity, while mechanical routes rely on surfactants for processability. The industry still lacks a graphene material that combines performance, processability, and scalable cost.
Typical thickness (1-10 layers)

Note: We have 3 standard functionalizations available and can create new customized ones on request.
Electrochemical exfoliation:
A patented (No. EP3732315B1 & EP4530375A1) aqueous process gently separates graphite into large, thin, few-layer graphene flakes — preserving high conductivity and flexible 2D morphology.
In-situ functionalization:
Functional groups are introduced during exfoliation, helping prevent restacking and enabling stable, surfactant-free dispersions (incl. the world's first Graphene dispersion in water), pastes, and agglomerates.
Scalable production:
Sixonia is scaling eGraphene through automated, modular production units designed for repeatable industrial supply and local capacity expansion.
eGraphene is available as dispersion, paste or (dry) agglomerates. Other formulations such as eGraphene free-standing films, inks or composite-mixes with resins or polymers are available on request.
Low-solid (0,1 - 0,5 wt-% solid content) eGraphene dispersions in water, NMP, DMF, DMSO, alcohols, or other selected solvents (without surfactants)
Higher-solid (2-4 wt-% solid content) eGraphene pastes (without surfactants) where higher material concentration is needed.
Wet or Dry eGraphene agglomerates for processes that introduce shear forces and disperse eGraphene during mixing, like e.g. dry coating.
eGraphene production is designed to scale through automated container units rather than a single centralized mega-plant. This allows Sixonia to expand capacity step by step, reduce manual labor, and place production closer to customers when demand reaches industrial volumes.
Our pilot line supplies customer validation projects, application development, and early commercial demand.
The next scale-up step is a semi-automated containerized production unit with 2–10 t/a capacity, designed for repeatable, modular expansion.
Multiple automated production units can be combined into a distributed production fleet, enabling >100 t/a capacity and local supply close to strategic customers.

Supported by:
eGraphene supports multiple battery cell components — from conductive additives in cathodes and anodes to current collector primers and functional interface coatings for next-generation cells.
2D eGraphene networks create stable electrical contacts in wet and dry-coated electrodes — reducing additive loading, improving compression & adhesion. eGraphene has been validated across key cathode & anode systems — from LFP, NMC, sodium, sulfur, & LNMO cathodes to silicon, silicon-graphite, graphite, SCC, & LTO anodes.
Thin conductive eGraphene layers improve current-collector contact and support adhesion — enabling thinner primer coatings for wet- and dry-coated electrodes on both aluminum and copper current collectors.
Conductive, lithiophilic, and chemically tunable eGraphene layers stabilize critical battery interfaces. eGraphene interface coatings support multiple use cases — from solid electrolyte and separator coatings to active material coatings, lithium-metal deposition control, anode-free interfaces, and functional membranes.
Beyond batteries, eGraphene adds barrier properties, mechanical stability, and electrical or thermal conductivity to advanced coating systems. Typical applications include anti-corrosion coatings, EMI/EMC shielding, moisture barriers, fire- and heat-protective coatings, conductive films, thermal management coatings, and resin or adhesive systems.
Dry electrode manufacturing changes the requirements for conductive additives. Beyond conductivity, particle flow and calendering behavior can become critical factors for successful electrode production.
In established Li-ion chemistries, energy density is increasingly limited by inactive material. Learn how conductive additives influence active material share, electrode compression, and ultimately cell performance.
Current collector primers are among the thinnest layers inside a battery cell, yet they strongly influence conductivity and adhesion. Can the same functionality be achieved with significantly less material?
Most battery materials have a single function. eGraphene is being explored across cathodes, anodes, dry coating, current collector primers, and Li-metal interfaces—making it a potential platform material for battery design.
Lithium-metal batteries are often limited by what happens at the interface. Explore how ultra-thin carbon coatings can influence lithium deposition, contact stability, and next-generation battery architectures.
Graphene has long promised to transform battery performance, yet it has not become a standard battery material. The reason is not conductivity—it is the challenge of combining performance, processability, and scalability.
