More eventseGraphene is introducing a third conductive carbon material for batteries - beyond CNT and Carbon Black. It's functionalized, thin, large 2D flakes are an ideal additive to enable better batteries.
eGraphene combines high conductivity, ultra-thin, few-layer morphology, and large, flexible 2D flakes — making it well-suited for conductive networks and functional layers within battery cells. It can be integrated into wet and dry battery processes as a conductive additive, a current-collector primer, or an interface coating.
Conductivity up to 140,000 S/m, enabling high-performance at low-loadings
In-situ functionalization prevents restacking and enables tunable surface chemistry.
Large, flexible 2D flakes — 0.5–1 µm wide and below 3 nm thin — form networks, films, and particle coatings.
Surfactant-free formulations for wet and dry processing.
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.
Supported by:
eGraphene's functionalized few-layer morphology supports conductivity, electrode adhesion, and processability across both wet and dry coating routes.

In cathode formulations, 0.2wt% eGraphene + 0.2wt% carbon black has shown conductivity comparable to a 2wt% carbon black reference — allowing up to ~1.6wt% more active material.
eGraphene impact:
1,6 %
more active material at comparable performance and cost per kWh
In customer testing, eGraphene-containing electrodes showed 2–3% higher compression during calendering compared with carbon black or CNT reference systems.

eGraphene can improve electrode cohesion and adhesion to the current collector. In selected formulations, this has supported binder reduction of up to ~30% while maintaining mechanical electrode integrity.

2D eGraphene flakes can act as a lubricant during dry mixing and granulate calendering.
Better flow and dispersion help active material particles form more uniform dry-coated electrodes.
Selected trials enabled more uniform cathode and anode layers well below 100 µm.
Open to a technical exchange? We’d love to dive in.
Current collector primers are becoming critical for dry-coated electrodes, where they must provide electrical contact, adhesion to the current collector, and mechanical robustness during calendering.
eGraphene forms conductive 2D networks at very low loading. This can reduce conductive carbon demand and leave more formulation space for binder — enabling thinner primer layers, potentially below 500 nm, while maintaining conductivity and adhesion.
The impact: thinner primer coatings, less material use, and a potential path to lower coating costs.

eGraphene combines a conductive 2D structure, tunable surface chemistry, lithiophilic behavior, and interface-stabilizing functionality. Together, these properties enable ultra-thin carbon coatings for critical battery interfaces.
The bronze color on the backside of the coated PET foil indicates lithium intercalation into eGraphene, confirming its lithiophilic behavior. The deposited lithium layer on the right shows how eGraphene can support more uniform lithium distribution at the interface.
Li-Metal Inferface
Conductive, lithiophilic eGraphene layers stabilize lithium interfaces — improving contact and reducing degradation.
Li-Metal Deposition
Lithiophilic eGraphene coatings guide lithium nucleation — enabling smoother plating and lower dendrite risk.
Active Material Coating
Large 2D eGraphene flakes wrap active material particles — improving particle-to-particle conductivity at lower additive loading.
Separator Coating
Ultra-thin eGraphene layers add barrier functionality to separator surfaces — reducing side reactions and improving interface stability.
Membrane Coating
eGraphene coatings create conductive barrier layers on ion-transport membranes — reducing crossover while maintaining transport performance.
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.
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.
