It will be marketed in the form of nonwoven sheet for separators in lithium ion batteries (LIBs) with commercial production targeted for 2014.<\/p>\n<p>The aramid nanofiber sheet maintains its shape even at 300\u00b0C. It is also highly resistant to oxidation. Such features are expected to enhance the safety of high-power, high-capacity, energy-dense LIBs for vehicles and stationary storage, offering significant advantages over conventional separators in terms of reducing the risk of ignition in high-capacity, energy-dense applications.<\/p>\n<p>Other features of the product expects to achieve with the nonwoven sheet for battery separators include;<\/p>\n<ul>\n<li>High porosity promotes smooth mobility of the electrolyte, resulting in higher output and faster charging.<\/li>\n<li>Large surface area, a feature of nanofibers, as well as high porosity, hold the electrolyte effectively to maintain battery performance at low temperatures, when ion conductivity drops.<\/li>\n<li>As a nonwoven sheet, absorbs electrolyte more rapidly than conventional polyolefin-based separators, helping to shorten the time required to pour electrolyte into the battery, thereby reducing the production cost of large batteries.<\/li>\n<\/ul>\n<p>Teijin expects to develop other applications for its thin, heat-resistant aramid nanofiber sheet, such as separators for capacitors; high-performance, heat-resistant filters; and heat-resistant cleaners for office automation equipment.<\/p>\n<p>[rssless][connections id=&#8217;9&#8242;][rssless]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Teijin Techno Products have announced the development of
