SWeNT to Discuss Effectiveness of its Carbon Nanotubes in Lithium-Ion Batteries

At the 2012 Nanotech Conference and Expo, SouthWest NanoTechnologies (SWeNT)’s Director of Research and Development, Ricardo Prada Silvy will deliver a presentation entitled, ‘Specialty Multi-Walled Carbon Nanotubes for Advanced Li-ion Battery Cathodes.’

In the presentation, Prada Silvy will describe the latest developments in the SWeNT carbon nanotubes’ efficacy in lithium-ion batteries. SWeNT’s specialty multi-wall carbon nanotubes demonstrate easier dispersion and superior electrical conductivity when compared to other multi-wall carbon nanotubes in commercial quantities.

Prada Silvy informed that the company is happy about the research results according to which 1% wt of SWeNT specialty multi-walled carbon nanotubes are capable of substituting 6% wt typical conductive carbon-P used in the current formulation of lithium-ion battery cathodes, thus providing enhanced performance in rate capability, improved specific energy, augmented cycle life, and minimal impedance in high power electrodes. Optimal control over the carbon nanotube structure, which includes lower structural defects, less number of walls, higher aspect ratio and morphology, and high purity levels are the basis of these performance properties.

SWeNT will also display its SMW specialty multi-wall carbon nanotube line of products, SMW200 and SMW210. These grades are utilized as additives to improve the performance of lithium ion battery cathodes and provide superior electrical conductivity in polymer compounds. The company will also introduce its new single-wall carbon nanotube product called the SG65i, which has more content of semiconducting single-wall carbon nanotubes designed for printed semiconductor devices.

SWeNT’s semi-conductive and conductive carbon nanotube inks for use in displays and flexible printed electronics are relied on V2V Ink, a technology devised by alliance partner,Chasm Technologies. With single-wall carbon nanotubes, printing of these inks can be done utilizing commercial, high-volume printing techniques and equipment such as screen printing, gravure and flexographic.
