Asahi Kasei opened a new Hipore wet-process lithium-ion battery separator coating line in Charlotte, North Carolina, according to a weekly industry roundup. The company also introduced a lithium pre-doping technology for high-voltage lithium-ion batteries with silicon-based anodes.
The separator coating line expands Asahi Kasei's battery materials production footprint in the United States as demand for electric vehicle components and grid storage grows. Battery separator capacity has become a strategically important segment of the specialty chemicals and materials sector.
