Asahi Kasei to enhance manufacturing infrastructure for LIB separator
Asahi Kasei Corp.
Asahi Kasei will enhance its manufacturing infrastructure for Li-ion battery (LIB) separator* as described below, with completion scheduled for the first half of fiscal 2021.
Rapid growth of the LIB market is primarily driven by automotive applications due to increasing demand for electric-drive vehicles and by energy storage systems (ESS) due to greater adoption of renewable power sources. Asahi Kasei, the world’s leading LIB separator manufacturer, supplying both wet-process and dry-process separators with its Hipore™ and Celgard™ products, has been proactively expanding this business.
Outline of the manufacturing infrastructure enhancement
1) New capacity expansion
- Hipore™ LIB separator (wet process)
Celgard™ LIB separator (dry process)
- Moriyama, Shiga, Japan, and North Carolina, the US
(within existing plant grounds)
- ≈¥30 billion
- First half of fiscal 2021 (scheduled)
2) Rationalization and productivity improvements
Streamlining and consolidation of existing production facilities and product grades
These measures will result in a 300 million m2/year rise in wet-process capacity and a 150 million m2/year rise in dry-process capacity, for a total increase of 450 million m2/year.
Asahi Kasei’s total LIB separator capacity will be 730 million m2/year at the end of fiscal 2018, including wet-process capacity of 410 million m2/year and dry-process capacity of 320 million m2/year. Plant expansions currently in progress will raise total capacity to 1.1 billion m2/year upon completion in fiscal 2020, with wet-process capacity increasing to 700 million m2/year and dry-process capacity increasing to 400 million m2/year.
Completion of the measures announced today will further raise Asahi Kasei’s total LIB separator capacity to 1.55 billion m2/year in fiscal 2021, with wet-process capacity increasing to 1 billion m2/year and dry-process capacity increasing to 550 million m2/year.
In accordance with forthcoming demand trends, Asahi Kasei intends to raise its total LIB separator capacity, including both wet and dry processes, to 3 billion m2/year around 2025 in order to meet the growing needs of customers.
