Sino Applied Technology (SiAT), a Taiwan manufacturer of advanced nanomaterials for batteries, has partnered with Japan’s Zeon Corporation to introduce a single-walled carbon nanotube (CNT) conductive paste.
The solution is designed to replace or be combined with carbon black to act as a conductive agent additive in lithium-ion battery cathode/anode formulations. It also has applications in transparent films and electromagnetic (EMI) shielding.
Zeon produces single-walled carbon nanotubes (SWCNT) that feature properties including high aspect ratio, high purity and high specific surface area.
CNTs tend to undergo bundling and lack of dispersibility in aqueous and non-aqueous media. SiAT has designed technology to help overcome this, which it uses in the application of nanomaterial dispersion to manufacture CNT conductive paste.
Through the SiAT and Zeon partnership, the new SWCNT conductive paste aims to improve conductivity. The companies say that in battery cathode/anode formulation, the amount of SWCNT conductive paste required is only 1/20 of the amount of carbon black conductive paste required, which should enhance battery life and reduce charging times.
