Ultrapure and high performance LiFSI electrolyte salts, a key component of car battery cells, will speed up the development of new electrolyte formulations for the next generations of batteries, including semi-solid and solid state batteries, by significantly increasing their power, stability, cycle life and recyclability, while reducing charging time in high or low temperature conditions.

This industrial project will support the development of the European battery value chain and participate in the global need for carbon-neutral mobility.

Combining Arkema’s fluorochemicals expertise and Nippon Shokubai’s unique know-how in the industrial-scale production of high-purity LiFSI, both partners have joined forces in a strategic partnership that has led to the development of an innovative and integrated process. Based on this cutting-edge patented technology, a LiFSI fluorinated pilot production line has been installed on the Pierre-Bénite site and successfully came on stream in 2021.

To support the exponential growth in demand for battery cell materials, Arkema and Nippon Shokubai are taking a step forward by launching feasibility studies and establishing a joint venture to enable the mass-production of LiFSI electrolyte salts at Arkema’s Pierre-Bénite site in France by end-2025.
