Battery Separator Technology Partnership: Arkema, Senior Expand Strategic Cooperation

On February 3, Arkema and Senior, a global leader in battery separator technologies, signed a memorandum of understanding to reinforce their long-term collaboration and accelerate progress across the battery value chain. The battery separator technology partnership brings together complementary strengths to support innovation from material development to industrial-scale production.

Expanded scope of the battery separator technology partnership

Under the agreement, Arkema and Senior will deepen cooperation around Arkema’s current and future battery material portfolio alongside Senior’s advanced separator technologies and industrialization capabilities. This alignment is designed to create smoother integration between materials science and separator design while supporting scalable manufacturing needs.

Focus areas for next-generation batteries

The companies will jointly explore new battery technologies, including improved adhesion, advanced electrode coating solutions, low-temperature cell assembly processes, and semi-solid battery concepts. These areas are critical to addressing performance limitations and manufacturing challenges faced by next-generation battery systems. By combining Arkema’s expertise in specialty materials with Senior’s experience in separator engineering and large-scale production, the partnership aims to enhance battery performance, strengthen safety characteristics, and improve overall production efficiency across multiple battery applications.
