Electrolyte for Lithium-ion batteries

ProductIONEL™ LF-101
Common NameLithium bis(fluorosulfonyl)imide "LiFSI"
IONEL™

IONEL™ is LiFSI used as the electrolyte in Lithium-ion batteries. Nippon Shokubai developed the mass-production technology for LiFSI using proprietary synthesis and refining techniques for the first time in the world in 2013.
We decided to expand its production capacity of 2,000 MT/ year by 2023, adding to current production capacity of 300 MT / year, and we are planning further expansion to respond to the expected future increase in demand.
IONEL™ is highly pure, has few solvents and by-products, and exhibits stable electrochemical properties. IONEL™ has been adopted and certified by many battery manufacturers all over the world.
We have applied for patents suitable for Lithium-ion battery applications all over the world and own many patent rights. It complies with laws and regulations in major countries, so customers can use it with confidence in terms of quality and intellectual property.
