Japanese tech group Asahi Kasei will invest 30 billion yen (US$271 million) to expand its manufacturing capacity for lithium-ion battery separators, in response to “booming global demand in the battery market”.

Asahi Kasei will use the funds to increase production capacity by an additional 450 million square metres a year, taking the total capacity to 1.55 billion sq m, well beyond its target— stated in January 2018— of 1.1bn sq m by 2020.

The current 450m sq m expansion is scheduled for completion in mid 2021 across two factory sites— Moriyama in Japan and North Carolina in the US.

Daramic expands production at sites in Asia

Mon, 02/25/2019 - 00:00 -- John Shepherd

US-based lead-acid separator manufacturer Daramic has announced the opening of new polyethylene battery separator production lines in China and Thailand, to “support the growing demand” of customers primarily in Asia.

The introduction of one additional manufacturing line in Tianjin, China will double the company’s capacity at the location, while the new manufacturing line in Prachinburi, Thailand will increase capacity at the location by 20%.

As well as meeting Asian demand, the expansions will enable Daramic to balance operations globally in order to supply customers regionally, meaning that capacity that was previously “utilised to meet Asia demand can now be diverted to support customers in other global regions”.
