Japan based, Teijin Limited said it will inaugurate the second production line for Lielsort, an innovative separator for lithium ion secondary batteries (LIBs), to meet increasing market demand on December 24.

Teijin produces two types of Lielsort separators. One is a polyethylene-based material coated with the highly heat-resistant meta-aramid Teijinconex.

The other is coated with a highly electrode-adhesive, oxidation-resistant fluorine-based compound and both types are produced by Teijin Lielsort Korea Co., Ltd.

According to Teijin, the new production line will double Lielsort production capacity to respond to the expanding demand for coated separators.

“The line will also accelerate the development of a new type of Lielsort that Teijin is currently working on to achieve both higher heat resistance and adhesion for improved LIB safety,” it said.

Teijin utilized its expertise in polymeric chemistry to develop the world's first technology for simultaneously coating both sides of Lielsort.

It also developed a high-speed coating technology that is five times faster than conventional coating, with both technologies enabling more efficient production.

Teijin, which is working to establish Lielsort as the de facto standard for next-generation LIB specifications, is targeting Lielsort sales revenue of ¥2 billion by 2020.

Teijin’s main fields of operations are high-performance fibres like aramid, carbon fibres & composites, healthcare, films, resin & plastic processing, polyester fibres, products converting and IT.

It has some 150 companies and around 16,000 employees in over 20 countries worldwide and posted consolidated sales of ¥784.4 billion (USD 7.7 billion) in fiscal year ending March 31, 2014. (AR)
