Global specialty materials leader Arkema will unveil its latest innovations for electric vehicle (EV) and energy storage system (ESS) batteries at InterBattery 2026 in Seoul, showcasing technologies designed to boost performance, safety and sustainability in the next generation of battery systems.

 

At the show, Arkema will highlight how innovation contributes to higher performance, safety, and sustainability in next generation batteries.

 

The company has established itself as a key materials supplier enabling the rapid expansion of Lithium Iron Phosphate cathode technology. Since 2007, its Kynar HSV 900 has become the industry’s reference PVDF binder, powering more than 10 million EVs worldwide and countless energy storage systems thanks to its proven reliability, robust processing and outstanding cycling performance.

 

Building on this legacy, Arkema is expanding its LFP platform with newly developed PVDF grades — Kynar HSV 1200 and Kynar HSV 1400 — engineered to deliver stronger adhesion, reduced binder loading and higher active-material content to increase energy density.

 

Complementing these developments is the recently introduced Incellion range, which strengthens Arkema’s offering with solutions such as Incellion Pr 2510 and Incellion El 3020, designed to enhance adhesion, conductivity, durability and processing efficiency for next-generation LFP cells.

 

Arkema is also bringing decades of separator coating expertise to the exhibition through its Kynar Flex range, known for delivering strong mechanical integrity, excellent electrolyte wettability and superior thermal dimensional stability. The newest addition, Kynar Flex LBG 2600, improves manufacturing efficiency and allows for lower-temperature assembly.

 

Expanding this platform further, Arkema has introduced Incellion Sp 1252, an acrylic binder specifically designed for ceramic-coated separators. It provides exceptional mechanical strength, strong adhesion to polyolefin films and excellent electrolyte wettability, enabling separator designs that combine high safety margins with efficient ion transport.

 

Looking beyond today’s technologies, Arkema is accelerating material innovation for the next wave of batteries, including All‑solid‑state batteries, Semi‑solid batteries, and advanced dry-electrode manufacturing processes.

 

For semi-solid and solid-state architectures, the company is developing new generations of binder materials tailored for solid electrolytes, interface stabilization and high-voltage cathode compatibility — key enablers for safer, higher-energy battery designs.

 

At the same time, Arkema is pushing breakthroughs in dry-process-capable PVDF binders, helping cell manufacturers reduce energy consumption, eliminate solvent recovery steps and lower production costs. To support this effort, the company has opened a state-of-the-art dry coating laboratory in France, reinforcing its commitment to pioneering sustainable and advanced solutions for next-generation battery technologies.
