INTERFACE & PRIMER COATINGS

Coatings on active materials, current collectors, and other interfaces to improve mechanical properties, adhesion, cycling stability, and energy density with ultra-thin, conductive, and chemically stable eGraphene layers.

Especially, next-gen high-energy or dry-processed batteries are facing challenges at their interfaces. Where electrodes, current collectors, and electrolytes meet, poor adhesion, unstable contacts due to swelling or plating of active materials, and side reactions can lead to loss of conductivity, active material, and voids, as well as dendrite growth. These interfacial instabilities degrade performance, safety, and lifetime — long before the active materials reach their theoretical limits.

Active Material Coating

On both cathode and anode materials, eGraphene forms stable, uniform, conductive coatings that stabilize particle contact and improve electronic pathways.

Current Collector Coating

Applied as an ultra-thin primer, eGraphene enhances adhesion, conductivity, and corrosion resistance between metal foils and electrode layers.

Li-Metal Interface Coating

Between the current collector and Li-metal anodes, eGraphene forms a conductive, chemically stable interlayer that ensures uniform lithium plating and prevents void or dendrite formation.

INTRODUCING
eGRAPHENE

A black and green container labeled "Graphenes" by Sikona, featuring a hexagonal pattern. The container has a handle and a screw cap.

eGraphene is a few-layer, electrochemically exfoliated, and functionalized graphene made by a patented water-based process. Ready-to-use formulations provide a unique combination of chemical stability, electrical conductivity, and mechanical adhesion at the interface — achieved at very low loadings.
