On May 15 – 17, Arkema, a leader in Specialty Materials, attended the 17th China International Battery Fair (CIBF 2025) at the Shenzhen World Exhibition and Convention Center (Hall 10, Booth No. T032). Showcasing a comprehensive portfolio of solutions covering both inside and outside the battery cell as well as cutting-edge technologies for next-generation batteries. Arkema’s specialty materials are fully integrated into batteries’ ever-evolving lifecycles and boast abilities that optimize cell performance, improve thermal management and insulation safety, as well as respond to new technologies such as dry process, semi-solid and solid-state batteries.
At the exhibition, Arkema brought forth a comprehensive portfolio of multi-material solutions targeting the inside to the outside of battery cells. These solutions are the outcome of over 15 years of experience and knowledge accumulated in the field of battery materials. For the inside of the cell, Arkema’s solutions improve battery energy density, battery life and safety. For the outside of the cell, Arkema’s solutions are stable and sustainable with superior performance around thermal management, electrical insulation and structural integration. Participants would be able to see the many ways Arkema’s materials work in synergy so to support battery systems’ continuous improvement around safety, efficiency and durability.
Facing into new requirements for next-generation batteries such as higher energy density, safer structure and new electrolyte systems, Arkema is also showcasing several latest R&D results at the exhibition, demonstrating its innovative materials technologies in the areas of dry process, semi-solid or solid-state batteries. One of the solutions at the exhibition include: Kynar® PVDF's new solution for dry coating electrodes, the application of Kynar Ultra Flex® PVDF for all solid state systems, and a high ion conductivity, one-stop material combination for gel polymer electrolyte.
With the accelerated development of global electrification, battery technology is bringing new development opportunities. At this year’s CIBF, we have continued to champion our One Arkema synergy strategy and draw on the strength of many business departments here Arkema. This enables us to truly showcase Arkema's innovative specialty material solutions capable of promoting comprehensive breakthroughs in the next generation of batteries."
Inside of the cell
- Arkema's Kynar® PVDF is widely used in lithium-ion batteries’ electrode binders and coatings for separators. Kynar® PVDF electrode binders provide long-term stable electrochemical properties at high voltages, making them ideal for NMC, SI, LFP and LMFP battery systems. At the same time, Kynar® PVDF separator coating can greatly improve the adhesion to the positive and negative electrodes, making it suitable for fast-charging systems and significantly enhancing battery safety.
- Incellion™ waterborne acrylic series products provide optimized solutions for high-capacity anodes, cathode primers, and ceramic-coated separators, demonstrating high adhesion and excellent material stability and thermal stability
- Graphistrength® carbon nanotubes used in conductive pastes are easy to disperse and have good flowability, which can effectively improve the conductivity of the electrode, thereby achieving faster charging and stronger output capacity.
- Proionic® is an ionic liquid for a new type of electrolyte that is very stable under high heat and voltage, has excellent ionic conductivity and is non-flammable.
Outside of the cell
- As the flagship product of Arkema’s long-chain polyamides (including the Rilsan® PA11, Rilsamid® PA12, and Rilsan® HT PPA series), the bio-circular material Rilsan® PA11 offers outstanding flexibility and impact resistance, excellent long-term hydrolysis resistance, and low density, making it exceptionally lightweight. These properties make it particularly well-suited for the compact and space-constrained cooling circuits of electric vehicle battery thermal management systems, helping to ensure stable battery cooling and extending battery life. Rilsan® PA11 is also available in a range of flame-retardant grades and glass fiber-reinforced formulations, enabling it to replace conventional metal solutions in various valve bodies and connectors. In addition to its excellent dielectric insulation performance, Rilsan® PA11 offers significant advantages over PA12 in terms of heat resistance, impact strength, wear resistance, and ease of extrusion and bending processing. It has been selected as the insulation material for both internal and external battery busbars, providing safe and reliable insulation protection for single-layer and composite busbars in high-voltage connection systems. This material has been successfully adopted by leading new energy vehicle manufacturers.
- Notably, Rilsan® PA11 is derived entirely from 100% renewable castor beans, with a carbon footprint as low as 1.3 kg CO₂e/kg — approximately 80% lower than that of conventional petroleum-based polyamides — making it a preferred solution for many OEMs in their low-carbon transition efforts.
- Polyimide PI materials are mainly used for flexible circuit boards, electromagnetic wire insulation protection and structural parts processing in harsh environments, bringing extraordinary flexibility, high temperature resistance, electrical insulation, dimensional stability and chemical resistance.
- The high-voltage operation of the battery system places extremely high demands on the stability of the insulation layer. Sartomer® UV-curable liquid resins and monomers can effectively construct voltage-resistant, low-energy-loss insulation coatings to help maintain long-term electrical safety.
- The battery casing must be able to withstand external impact, corrosion, and even fire threats. In this regard, Elium® thermoplastic resin provides structural protection while being recyclable and can be adapted to common molding processes such as SMC and RTM, providing more possibilities for battery casing design.
- In response to the needs of battery structure bonding, Bostik provides fast-curing innovative adhesives that do not require complicated processing and are compatible with a variety of materials. They play a key role in new energy manufacturing that pursues assembly efficiency and thermal stability.
