Welcome to Hexagonal Nano New Material
This VGCF carbon nano fiber powder features ultra-high aspect ratio that forms a continuous 3D conductive network at low dosages, delivering outstanding electrical and thermal conductivity to significantly cut electrode internal resistance; it boasts high carbon purity with minimal metallic impurities to preserve battery cycle life, disperses well in water and organic solvents while matching multiple battery binders, and offers strong mechanical strength to stabilize electrode structures during charge and discharge. Suitable for lithium batteries, supercapacitors, conductive films, EMI shielding composites and thermal interface materials, the material supports customizable fiber lengths, surface treatments and bulk densities with free sample provision, and maintains consistent batch quality for large-volume industrial manufacturing.
Hex Nano supplies high-performance VGCF (Vapor Grown Carbon Nano Fiber) powder with ultra-high aspect ratio, excellent
electrical conductivity and outstanding thermal conductivity. Our carbon nanofiber features uniform fiber diameter, low
impurity content and good dispersion compatibility with solvents, binders and electrode materials.
As a superior conductive additive, VGCF carbon nano fiber powder forms three-dimensional conductive networks inside
lithium battery electrodes, supercapacitors and conductive composites. It effectively reduces internal resistance,
improves rate discharge performance and enhances cycle stability of energy storage devices. Widely applied in
lithium-ion power batteries, consumer batteries, conductive plastics, EMI shielding materials and thermal conductive
coatings. Custom fiber length, purity and surface modification are supported, and free test samples are available for
customers' formula verification.
Low addition amount, high conductivity, obvious cost reduction.
Boost battery fast charging & long cycle life.
Excellent thermal dissipation to avoid battery overheating.
High purity, no heavy metal contamination
Stable dispersion, easy for industrial coating processing
