Teijin will spend about $26 million to expand output of its Miraim microporous membranes in Japan.

Separately, Teijin will add a production line in South Korea for Lielsort separators used in rechargeable lithium-ion batteries, expanding capacity by 70%. The separators, already common in smartphones and tablets, will soon also be widely used in car batteries, the company claims.
