$33.15 billion is the projected size of the global carbon nanotubes market for EV batteries and electronics by 2035, up from $9.01 billion in 2025.
A 14.0% CAGR forecast reflects rising EV adoption, demand for higher-performance lithium-ion batteries, and broader use of CNTs in semiconductors, displays and other electronics.
Automotive and EV applications led the market in 2025 as battery makers used CNTs to boost electrode conductivity, energy density, durability and charging speed; multi-walled CNTs generated the most revenue.
North America was the leading regional market in 2025 on battery, EV and nanotechnology investment, while Asia-Pacific is forecast to grow fastest as China, Japan, South Korea and India expand EV and battery production.
Growth still faces a key constraint: CNT production remains costly and complex, with purity, consistency and safety requirements making scale-up harder than for cheaper conductive materials such as carbon black.
