Meltspun nanofibre first

TeijinTeijin and the Tokyo Institute of Technology have developed a highly crystalline carbon nanofibre (CNF) offering 30% greater electrical conductivity than existing products.
The extra-conductive CNF – which is 100-300 nanometres in diameter and 20 micrometers long – has been developed with a melt-spinning process – a world first for such a fibre.
Since melt spinning is widely used for the production of ordinary chemical fibres, the newly developed CNF can be manufactured on existing commercial technology, which will help to minimise manufacturing costs. In addition, it is possible to manufacture CNFs of high purity because no catalyst is used during the production process.
The primary application presently envisioned for the new CNF is in battery components, particularly lithium-ion batteries for electric vehicles, including electrodes and additives for secondary batteries and capacitors. Other likely uses include plastic additives and fuel-cell gas-diffusion layers.  Teijin aims to commercialise the new CNF in 2011.  Source nonwovenslive.com
