- Feasibility studies and a joint venture are being launched for an industrial plant to produce LiFSI electrolyte salts.
- LiFSI electrolyte salts are crucial for next-gen electric vehicle batteries, improving power, stability, and recyclability.
- A pilot production line was installed at Pierre-Bénite in 2021.
- Mass production at Arkema's Pierre-Bénite site is targeted for end-2025.
Project Overview
Nippon Shokubai and Arkema are collaborating to conduct feasibility studies and form a joint venture to build an industrial plant for producing LiFSI (Lithium bis(fluorosulfonyl)imide) ultrapure electrolyte salts. These salts are essential for battery cells used in electric vehicles.
Importance of LiFSI Electrolyte Salts
LiFSI electrolyte salts are critical for the development of new electrolyte formulations for next-generation batteries, including semi-solid and solid-state batteries. They enhance battery performance by increasing power, stability, cycle life, and recyclability, while also reducing charging time in various temperature conditions.
European Battery Value Chain
This project aims to bolster the European battery value chain and contribute to the global demand for carbon-neutral mobility. The collaboration leverages Arkema’s expertise in fluorochemicals and Nippon Shokubai’s experience in producing high-purity LiFSI on an industrial scale.
Technological Advancements
The partnership has developed an innovative and integrated process based on patented technology. A pilot production line for LiFSI fluorinated salts was successfully installed at the Pierre-Bénite site in 2021.
Future Plans
To meet the growing demand for battery cell materials, Arkema and Nippon Shokubai are moving forward with feasibility studies and establishing a joint venture. The goal is to enable mass production of LiFSI electrolyte salts at Arkema’s Pierre-Bénite site in France by the end of 2025.
