Global Single-Walled CNTs Market Strategic Research Report

Scope of the Report

The global Single-Walled CNTs market size is predicted to grow from US$ 364 million in 2025 to US$ 5,603 million in 2032; it is expected to grow at a CAGR of 48.3% from 2026 to 2032.

Single-walled carbon nanotubes (SWCNTs) are seamless hollow tubular structures formed by the curling of a single layer of graphene, with diameters typically ranging from 1 to 2 nanometers and lengths reaching the micrometer scale. Their unique one-dimensional nanostructure endows them with exceptional mechanical properties (elastic modulus up to 1 TPa), electrical properties (conductivity 100 times higher than copper), and thermal properties (thermal conductivity exceeding 3000 W/m・K), earning them the title of “King of Nanomaterials.”

Production technology: The mainstream method is high-temperature chemical vapor deposition (CVD), which requires precise control of catalysts (such as iron and cobalt) and reaction conditions to achieve high-purity mass production. Russian OCSiAl has achieved large-scale production through its proprietary “Super Growth” technology, while Chinese companies such as Tiannai Technology and Guizhou Xicheng have overcome technical bottlenecks using fluidized bed CVD and third-generation horizontal furnace CVD equipment.

Core Characteristics:

Conductive Network Advantage: Adding a small amount (0.1%-1%) to lithium-ion batteries forms a long-range conductive network, significantly enhancing battery energy density (up to 400-500 Wh/kg) and cycle life (over 2,000 cycles).

Biocompatibility: Its high specific surface area (1,300 m²/g) makes it suitable for medical applications such as brain-computer interfaces, including non-invasive EEG signal acquisition.

Semiconductor Application Potential: It can replace copper wires in chip manufacturing processes below 3nm, improving thermal conductivity by 41% and helping to address computational power bottlenecks.

Global production of single-walled carbon nanotubes reached 234 tons in 2024, with an average selling price of USD 1.25 million per ton.

Application area distribution:

Lithium-ion battery sector: Over 80% share, primarily used in power batteries (electric vehicles, eVTOL aircraft) and industrial energy storage (AI server BBU, renewable energy ESS). The increasing penetration of silicon-based anodes (global demand of 2,000 tons by 2025) further drives SWCNT demand, with a single-walled tube powder addition ratio of 2%-4%.

Emerging applications: Rapid expansion in fields such as semiconductor packaging (TSMC's 3nm process), flexible electronics (wearable devices), and brain-computer interfaces (Neuralink technology upgrades), with non-battery applications expected to account for over 30% by 2030.

Technological breakthroughs and industrialization:

Scalable production: Tianai Technology's “450-ton-per-year SWCNT project” is being developed in three phases, with the first phase expected to commence production in 2025; Guizhou Xicheng's “4,700-ton-per-year SWCNT/AWCNT project” fills a domestic gap and is projected to achieve full production capacity by 2026.

Dispersion Technology Optimization: Carbon Peak Technology has developed the third-generation horizontal furnace CVD equipment, reducing the constant temperature time by 50% and achieving a purity of over 98%; Tianai Technology has achieved uniform dispersion of single-walled tubes in electrode slurry through its self-developed dispersant.

Semiconductor application deployment: TSMC's 3nm process adopts SWCNT chip interconnects, while Huawei and SMIC have initiated testing for processes below 2nm, with conductivity 10 times higher than copper.
