The market for CNTs will exceed $750m within the next decade.
Carbon nanotubes (CNTs) have been known for many decades, but the moment of significant commercial growth is just approaching. Through expansions, partnerships, acquisitions, and greater market adoption there are clear indicators that now is the time for true market success to be realised.
This report gives granular 10-year market forecasts, player analysis, technology benchmarking, and a deep-dive in core application areas. This detailed technical analysis is built on a long history in the field of nanocarbons and is based on primary-interviews with key and emerging players.
The potential for CNTs needs no introduction. If the exciting nanoscale properties, from mechanical to thermal & electrical conductivity and beyond, can be realised then the global impact will be profound. However, as is well known the reality is much further from the theoretical ideals.
There is a wide range of technology and manufacturing readiness for the different types of nanotubes. Making the nanotubes is just the first step, a large amount of consideration needs to go into understanding how they can be functionalised, purified and/or separated, and integrated. This report goes into extensive detail benchmarking the physical and economic properties of MWCNTs, FWCNTs, and SWCNTs, it extends to key advancements in this post-processing and dispersion technology, which is an essential part for any market success.
There is also the trend to making "macro-CNT" products most commonly in the form of sheets/veils or yarns. There are numerous technical challenges in translating the core beneficial properties from the nanoscale but some promising results and emerging applications are being observed; within this vertically aligned CNTs (VACNTs) are one of the most exciting areas taking advantage of the inherent anisotropy of the nanotubes.
It is also important to consider the incumbent and emerging competition. In most applications the CNTs are acting as an additive and competing against others from chopped carbon fiber to carbon black and graphene, the combination of properties are essential for adoption and looking beyond to non-tradition figures-of-merit can give indication of where the market potential lies.
MWCNT production has been established for a long time with most employing a catalytic CVD process, but there remain technical and economic improvements to the MWCNT production and how they are post-processed. This report details the key manufacturers and those further up the supply chain, geographically China has taken a dominant position and leads the way in both installed and planned capacity
For MWCNTs there are 3 key news stories: the funding raised and planned expansion of Jiansgu Cnano Technology, the new LG Chem capacity, and the acquisition of SUSN by Cabot Corporation. Most of this movement is linked with the energy storage market and the role CNTs can play as conductive additives for either electrode in both current and next-generation lithium-ion batteries.
This is not the first-time this expansion has been planned, as seen in the figure below. In the build up to 2011, there were several expansions that ultimately proved premature; as a result some players left the field and a subsequent period of capacity stagnation was observed. However, during this period utilisation grew and end-users continued to experiment and find application areas where there is genuine added value. Beyond 2020, we are entering into a new age of expansions, the demand from LiBs and other applications suggests there is good reasons in expecting the timing to be right this time.
SWCNTs are at an earlier stage but there is still a high-level of commercial activity. There is more diversity in the manufacturing from using CO feedstocks to plasma processes and combustion synthesis, this report goes through each of these processes with key profiles and player analysis. With key partnerships being established, some expansion and crucially some market activity these materials are at their start of their commercial 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 shielding cables and coatings but the key sectors are as an additive in energy storage and polymers.
- Energy storage: Driven by the demand for electrification this market is booming and CNTs are well positioned. The nanotubes act as a conductive additive for either electrode in both current and next-generation lithium-ion battery designs, incorporation of a relatively small weight % can have a significant boost to energy density. The enhanced conductivity is obvious, but the mechanical properties are also very important in providing anchorage that enables thicker electrodes, wider temperature range, or materials that give a higher capacity. How they are dispersed, used with or without a binder, and combined with other additives are all examined in extensive detail within the report. Although lacking the same addressable market, there are also key developments in the role of CNTs for ultracapacitors that are explored in a dedicated chapter.
- Polymer additives: either in a standalone polymer matrix or within a fiber reinforced polymer composite, CNTs can play a significant role through their blend of properties. This can range from improving interlaminar strength in composite layups to improving the electrostatic discharge capabilities. There are a range of more conductive polymers that have been explored, from epoxies to natural rubber, with players looking to find the sectors that require this value-add.
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 for such as memory, sensors, and other electronic applications.
