OSAKA -- Japanese chemical group Nippon Shokubai will build a 37.5 billion yen ($263 million) plant to produce a material that can lengthen the life of an electric vehicle battery by around 60%, Nikkei has learned.

The plant will produce lithium bis(fluorosulfonyl)imide (LiFSI), a newer type of lithium-ion battery electrolyte. Production is expected to begin in 2028.
