Asahi Kasei to boost battery component output by 30%

World's top separator maker readies to meet demand for eco-friendly autos

Asahi Kasei is the world's leading maker of separators, which are used in batteries.

TOKYO -- Japanese chemical company Asahi Kasei will increase its output of separators used in lithium ion batteries by 30%, hoping to meet rising demand for electric vehicles as emissions and fuel efficiency standards become stricter worldwide.

By 2019, Asahi Kasei will spend from 11 billion yen to 19 billion yen ($99 million to $171.1 million) to bolster production; the decision may have come after getting large orders from U.S. electric-vehicle maker Tesla and other companies. Separators prevent batteries from overheating or catching fire. Battery demand is growing for cars, as well as for devices like personal computers and smartphones.
