At The Battery Show Europe 2023 - Stuttgart, Germany, May 23-25, Booth J35 - Hall 10, Arkema is releasing a full range of specialty materials and more sustainable solutions for use both inside and outside of electric vehicle (EV) and energy storage system (ESS) batteries. Here are a few of the innovations Arkema will be showcasing at The Battery Show this year: More sustainable performance inside the cell Ultra-high purity foranext® lithium salts Solutions for thermal management Lower carbon footprint Rilsan® Polyamide 11 for EV Busbars Innovation for more circular “End of life” Anthony BONNET, Global Energy Scientific Director Slide 1 of 2 VP Communication +33 (0)1 49 00 70 07 Corporate Press relations manager +33 (0)6 81 87 48 77
Arkema's flagship Kynar ® PVDF will be showcased as high-performance material with a proven legacy for battery cell manufacturing. Kynar® PVDF is an efficient solution as an electrode binder and edge coating allowing an outstanding performance throughout the cells' service life. PVDF is a material of choice as a binder and adhesive layer for battery cell separator coatings.
Arkema will present its Foranext® LiFSI lithium salt, well-known for its best-in-class conductivity. The ultra-high purity and stability of Foranext® LiFSI helps tremendously with the capacity retention of the battery cell – adding high concentrations of LiFSI in the electrolyte will improve the lifetime of batteries. Also, Foranext® LiFSI stability in water is compatible with hydrometallurgy recycling processes. LiFSI is stable in water, enhancing safety (no additional HF generation) but also gives LiFSI a great recovery potential.
New Incellion™ waterborne acrylic solutions
Arkema recently introduced new acrylic-based solutions targeting higher cell performance with faster charging, longer life-cycle durability, and increased energy density while ensuring world class safety and environmental compliance.

Innovation outside the cell
Bostik, Arkema's specialty adhesives business, introduces thermal conductive adhesives (TCA) for bonding battery cells and managing heat in Cell-to-Pack designs. The XPU TCA 202 is a two-component, polyurethane-based adhesive specifically designed for heat dissipation in battery pack assemblies. It perfectly tackles the challenge to balance thermal conductivity with high mechanical strength while maintaining good levels of flexibility thanks to high elongation. Its low-monomer content allows to meet most stringent regulations and enables easy product handling without specific training. At a practical level it is also fast and easy to process through automatic mixing, dosing and dispensing equipment. It adheres well to most substrates without using a primer, and cures at room temperature. The launch follows the recent announcement - on May 17th - of the planned acquisition of Polytec PT by Arkema.
100% Bio-based Oleris® material for dielectric fluids for direct fluid immersion cooling systems is derived from renewable castor oil, enhances dielectric fluids in battery direct liquid immersion cooling systems. The 100% bio-based n-heptanoic acid and carbon-neutral C7 fatty acid enables the synthesis of high-performance polyol esters, resulting in dielectric fluids with low viscosity, lower pour point, excellent oxidation stability, and biodegradability. This technology marks a major step forward in the development of more sustainable solutions for battery thermal management.
Solutions for lower energy intensive dielectric insulation
With the emergence of electric mobility, new solutions that allow decarbonization are emerging. New solvent-free UV technology enables low energy consumption, instant drying and ease of application, which are key factors for efficiency and mass production of dielectric coatings for battery cells. The high performance Sartomer® UV curable specialties are enabling this transition, providing excellent dielectric properties, adhesion and flexibility.
By leveraging Group synergies with Bostik adhesive solutions and expertise, Arkema is identifying opportunity to develop solutions with unrivaled adhesion properties between the coated battery cells.
100% Bio-based Rilsan® Polyamide 11, derived from renewable castor plants, for EV battery busbars, offers superior abrasion, thermal, and chemical resistance. Demonstrating its commitment to sustainability, Arkema has partnered with ENGIE to supply 300 GWh/year of renewable biomethane, further reducing the carbon footprint of Rilsan® Polyamide 11.
Arkema is collaborating with the Rhinoceros Project, a consortium dedicated to advancing sustainable reuse and recycling in lithium-ion batteries across the European Union. Hosting a recent meeting, the members focused on cost-effective and sustainable technologies for battery materials recycling and reuse. Recovering and recycling KYNAR® PVDF, widely used as a battery cell electrode binder, was a key area of discussion.
Arkema is investing in one of the most complete product portfolios in the battery industry, including more sustainable solutions for cell assembly, pack assembly, thermal management, management systems and fire protection.
