Carbon Nanotubes 2025-2035: Market, Technology & Players

After years of anticipation, the first significant market adoption of nanocarbons is being observed. Although carbon nanotubes (CNTs) have been known for decades and have attracted considerable commercial interest due to their exceptional properties, their use has largely been confined to niche applications with limited market penetration. Strong growth in the CNT market is forecast by IDTechEx over the coming decade, primarily driven by their role in energy storage.

 

A comprehensive overview of the CNT industry is provided in this market report, including manufacturers, material and process landscapes, applications, and market forecasts.

 

Carbon nanotubes (CNTs) have been known for many decades, but significant commercial growth is now being realized. Indicators of true market success are evident through expansions, partnerships, acquisitions, and increased adoption across key sectors.

 

Granular 10-year market forecasts, player analysis, technology benchmarking, and in-depth examinations of core application areas are presented in this report. The detailed technical analysis is underpinned by extensive experience in the nanocarbon field and is based on primary interviews with both established and emerging industry players.

 

The potential of CNTs is widely recognized. If their superlative nanoscale properties ranging from mechanical strength to thermal and electrical conductivity, can be fully realized, the global impact could be substantial. However current performance remains far from theoretical ideals.

 

A wide range of technological and manufacturing readiness levels exists across the different types of carbon nanotubes. Production represents only the initial step; extensive consideration must be given to their functionalization, purification, separation, and integration. This report provides detailed benchmarking of the physical and economic properties of multi-walled (MWCNTs), few-walled (FWCNTs), and single-walled carbon nanotubes (SWCNTs), and highlights key advancements in post-processing and dispersion technologies - critical components for achieving market success.

 

A growing trend is also being observed in the development of "macro-CNT" products, most commonly in the form of sheets, veils, or yarns. While significant technical challenges remain in translating the intrinsic nanoscale properties to larger-scale formats, promising results and emerging applications are being reported. Among these, vertically aligned carbon nanotubes (VACNTs) represent one of the most compelling areas, leveraging the inherent anisotropy of the nanotubes.

 

Consideration must also be given to both incumbent and emerging competitive materials. In most applications, CNTs function as additives and face competition from other conductive carbon materials such as chopped carbon fiber, carbon black, and graphene. Adoption depends on a combination of properties rather than a single metric and evaluating non-traditional figures of merit can provide valuable insight into where the strongest market potential resides.

 

MWCNT production has been established for some time, with catalytic chemical vapor deposition (CVD) being the most commonly employed method. However, both technical and economic improvements are still needed in production and post-processing. This report outlines the key manufacturers and upstream supply chain players, noting that East Asia has taken a dominant position, leading in both installed and planned production capacity.

 

Three key developments are shaping the MWCNT landscape: the continued expansion by Jiangsu Cnano Technology, the increasing production capacity at LG Chem, and the acquisition of notable CNT players by major carbon black multinationals. These advancements are primarily tied to the energy storage sector, where CNTs serve as conductive additives in both current and next-generation lithium-ion battery electrodes. Other companies are also making significant progress, and with industry consolidation expected, the current environment presents a pivotal moment for market growth.

 

Widespread expansions have been planned previously. In the lead-up to 2011, multiple production scale-ups were initiated but ultimately proved premature, leading to the exit of several players and a subsequent period of capacity stagnation. However, during this time, utilization steadily increased as end-users continued to explore and identify applications offering genuine added value. Since 2020, a new wave of expansion has emerged, now driven by the increasing use of CNTs in lithium-ion battery cathodes amid rapid growth in the electric vehicle market.

 

 

Single-walled carbon nanotubes (SWCNTs) are at an earlier stage of commercialization, yet significant commercial activity is already underway. A broader diversity of manufacturing approaches is observed, including CO-based feedstocks, plasma processes, and combustion synthesis. This report examines each of these methods in detail, featuring key player profiles and analysis. With strategic partnerships forming, initial production expansions taking place, and early market engagement emerging, SWCNTs are now entering the initial phase of their commercialization journey.

 

This report provides granular 10-year forecasts for MWCNTs and DWCNTs & SWCNTs segmented by end-use application.

 

MWCNTs have numerous application areas from thermal interface materials to coatings but the key sectors are as an additive in energy storage and polymers.

 

Energy storage: Driven by the growing demand for electrification, the CNT market is experiencing rapid growth, with nanotubes well positioned to meet emerging needs. As conductive additives in both current and next-generation lithium-ion battery electrodes, even a small weight percentage of CNTs can significantly enhance energy density. While improved conductivity is a primary benefit, the mechanical properties of CNTs also play a critical role, supporting thicker electrodes, expanding operational temperature ranges, and enabling the use of higher-capacity materials. Their dispersion methods, binder compatibility, and interaction with other additives are explored in extensive detail within this report. Although the addressable market is smaller, important advancements in the use of CNTs in supercapacitors are also examined in a dedicated chapter.

 

Polymer additives: Whether embedded in a standalone polymer matrix or integrated into fiber-reinforced polymer composites, CNTs can provide substantial benefits due to their unique combination of properties. These include enhancements in interlaminar strength for composite layups and improved electrostatic discharge performance. While there have already been notable long-term successes, such as in fuel systems and electronic packaging, the rising volumes driven by energy storage demand, along with decreasing costs, are expected to unlock a broader range of applications in the coming decade.

 

SWCNTs will compete with MWCNTs, particularly as additives for energy storage and elastomer applications, but given their unique properties they are also gaining traction in novel areas such as memory, sensors, and other electronic applications.
