CNT (Carbon Nanotubes) Global Shipment Volume Expected to Approach 4,000 Tons by 2023

Yano Research Institute (the President, Takashi Mizukoshi) has conducted a survey on the global carbon nanotube market for 2018, and has found out the trends by product segment, trends of market players, and the future outlook.

Market Overview

The global market size of carbon nanotubes in 2018, based on the shipment volume at manufacturers, is expected to attain 2,255.8 tons, 118.5% of the size of the previous year.

Amongst the CNT market, the prices of SWNTs (single-walled nanotubes), which used to be high, have started falling to encourage extensive adoption for conductive coatings, antistatic coatings, thermosetting resin composites, glass, asphalt, and automobile tires. On the other hand, MWNTs (multi-walled nanotubes) especially for conductive auxiliary agent used for lithium ion secondary batteries have become extremely required in China due to remarkably growing number of EVs and PHEVs produced and sold.

Noteworthy Topics

For positive electrode of lithium ion batteries, internal resistance of a LiB can be reduced by adding conductive auxiliary agent. When the charging and discharging cycle increases, discharge capacity of LiB decreases. One of the reasons for this is loss of contact points among particles of active materials. Because conductive auxiliary agent functions to keep the connection between active-material particles after their loss of points of contact, even if charging and discharging have been repeated, adding of the agent keeps the form of an electrode to enable it to secure the conductive path. This eventually prolongs the LiB life. For conductive auxiliary agent, MWNTs, carbon black, graphite powder, and etc. are used. 


The global market size of LiB conductive auxiliary agent, based on the shipment volume at manufacturers, is projected to exceed 10,000 tons, among which MWNT is expected to occupy a little over 15%.

Global CNT (Carbon Nanotube) Market

Carbon nanotubes are carbon allotropes structured with cylindrical-shaped graphite sheet. Generally speaking, they indicate those with the diameter 1 to some tens of nanometers, with the length 1 to some tens of µm. This report has dealt with broader sense of CNT to include “VGCF®”, the similar structure of CNT with the diameter excluding 100 nm made by SHOWA DENKO K.K.
