Arkema Presents Battery Materials Portfolio at Interbattery 2026

Battery materials for electric vehicles and energy storage systems
In electric vehicle (EV) and energy storage system (ESS) manufacturing, the choice of materials directly influences battery performance, durability, and safety. At Interbattery 2026 (11–13 March, Seoul, South Korea), Arkema is presenting a portfolio of specialty materials designed to support next-generation battery architectures and manufacturing technologies. Visitors can meet the company’s team at Booth C520, where solutions for cathodes, separators, battery assembly, and thermal management are showcased.

The materials portfolio addresses multiple stages of battery design and production, including electrode formulation, separator coatings, electrical insulation, and structural assembly for battery modules and packs.

Materials supporting LFP cathode technology
Lithium iron phosphate (LFP) batteries are widely used in electric mobility and stationary energy storage due to their long cycle life and improved thermal stability compared with some alternative chemistries. Arkema has developed a range of polyvinylidene fluoride (PVDF) binder materials used in LFP cathode manufacturing.

The company’s Kynar HSV 900 binder has been used in large-scale battery production since 2007 and is employed in EV and energy storage applications worldwide. The binder plays a role in maintaining electrode structure by bonding active material particles to the current collector while ensuring electrical conductivity and mechanical stability during repeated charge–discharge cycles.

Building on this technology platform, Arkema has introduced additional PVDF grades designed to improve electrode formulation. The newer Kynar HSV 1200 and HSV 1400 materials aim to enhance adhesion and enable lower binder loading, allowing a higher proportion of active material within the electrode and potentially increasing energy density.

Complementing these materials, the Incellion product family includes solutions such as Incellion Pr 2510 for primer coatings and Incellion El 3020 for water-based silicon anodes. These materials are designed to improve adhesion, conductivity, and electrode durability during manufacturing and operation.

Separator coatings and binder technologies
Battery separators play a critical role in preventing electrical short circuits while allowing ion transport between electrodes. Arkema’s separator coating materials are based on its Kynar Flex PVDF technology, which contributes to mechanical integrity and electrolyte wettability.

The Kynar Flex LBG 2600 grade represents a recent development within this material family. According to the company, the material supports improved manufacturing efficiency by enabling separator processing at lower temperatures.

In addition, Arkema has developed Incellion Sp 1252, an acrylic binder designed for ceramic-coated separators. The material provides adhesion to polyolefin separator films while maintaining mechanical stability and electrolyte compatibility, factors that influence battery safety and ion transport performance.

Materials for solid-state and dry-process battery manufacturing
Battery manufacturers are also exploring new architectures, including semi-solid and solid-state cells, to increase energy density and improve safety. Arkema is developing binder materials adapted to these emerging technologies, with formulations designed to support solid electrolytes and stabilize electrode interfaces.

The company is also working on PVDF binders compatible with dry-electrode manufacturing processes. Dry coating technologies aim to reduce energy consumption and eliminate solvent recovery stages commonly used in conventional electrode manufacturing. To support this development, Arkema has established a dry coating laboratory in France dedicated to testing materials and production processes for next-generation battery manufacturing.

Materials for insulation, thermal management, and assembly
In addition to electrode materials, Arkema provides polymers, resins, and adhesives used in battery pack design and manufacturing.

Polyimide materials from the Zenimid range provide thermal resistance and dielectric strength for flexible printed circuit boards used in battery management systems. Polyamide materials such as Rilsan PA11 can be used in busbar insulation, contributing to electrical protection within battery packs.

Thermal management materials are also required to dissipate heat generated during battery operation. Rilsan PA11 and Rilsamid PA12 are used in cooling lines and connectors, while thermal interface materials developed by Bostik help transfer heat away from battery modules and packs.

Adhesives and sealants are used during battery assembly to bond structural components and seal battery housings. The Bostik product portfolio includes debond-on-demand solutions, gasketing sealants for battery enclosures, and structural adhesives used in cell-to-module and cell-to-pack assembly processes.

Materials supporting next-generation battery systems
Through developments in electrode binders, separator coatings, insulation materials, and assembly technologies, battery material suppliers are contributing to improvements in energy density, safety, and manufacturing efficiency.

At Interbattery 2026 in Seoul, Arkema is presenting these technologies as part of its broader strategy to support battery manufacturers developing electric mobility and stationary energy storage solutions.
