Often called the "workhorse conductive backbone" of modern lithium-ion batteries, VGCF (Vapor Grown Carbon Fiber) is a catalytic CVD-grown carbon nanofiber with ultra-high aspect ratio, excellent electrical/thermal conductivity, and outstanding mechanical strength.
Its core value in battery systems:
- Builds a robust 3D long-range conductive network inside electrodes, maintaining stable electron transport even as active materials expand and contract during cycling
- Reduces total conductive agent dosage, frees up space for active materials, and boosts cell energy density
- Enhances rate capability, suppresses electrode cracking, and extends battery cycle life significantly
- Works perfectly with LFP, NCM, silicon anodes and even solid-state battery systems
Market outlook:
The global VGCF conductive additive market is projected to grow at a ~25% CAGR through 2031, driven by fast-charging EVs, large-format energy storage and 4680 cylindrical battery adoption. It has become a standard high-performance solution alongside carbon black and carbon nanotubes.
Production & qualification update:
KLW Group has now reached 200 tons annual production capacity for battery-grade VGCF, with full quality validation from industry leaders including Camel Group, Daimler, and Microvast.
Hexagonal Nano (Hex Nano) is proud to serve as the official global operating partner of KLW Group, bringing high-quality, cost-competitive VGCF materials to battery manufacturers, material formulators and R&D institutions worldwide.
