oxidation resistance together with high quality.
Until now, aramid nanofibers have been produced only in laboratories, so this first commercially viable product represents a significant step forward in the evolution of this promising new material. Teijin Techno Products' nanofiber, which is uniformly sized with a diameter of just several hundred nanometers is based on Teijin's proprietary Teijinconex heat-resistant meta-aramid.
It will be marketed in the form of nonwoven sheet for separators in lithium ion batteries (LIBs). Commercial production is targeted at 2014.
