Acrylic based solutions for ceramic coating
Reinforce safety and stability for high‑performance Lithium‑Ion batteries
The separator’s ability to withstand thermal stress and mechanical strain is central to battery safety and lifetime. With operating conditions becoming more demanding across mobility and energy‑storage applications, manufacturers increasingly depend on materials that reinforce these essential properties.
Incellion™ Sp, Arkema’s acrylic-based binder solution for battery separator design, provides a new generation of materials engineered to reinforce separator durability and reliability.
Designed to address the key challenges of modern lithium-ion batteries, Incellion™ Sp enhances mechanical strength, improves thermal and chemical stability, and helps maintain consistent separator performance; all essential to support electric mobility, consumer electronics, and advanced energy storage systems.
Why Choose Incellion™ Sp?
More efficient formulation & handling
Compatibility and efficient dispersion of both Alumina and Boehmite ensure a stable and homogeneous formulation. The suitable rheology profile allows easy handling and uniform coating thickness distribution, while the solution offers excellent slurry stability to support consistent and reliable processing.
Less is more mechanical integrity
Uniform distribution of binder in ceramic coating ensures consistent coverage and stable layer formation. The solution provides excellent peel adhesion to the polyolefin membranes and strong binding of ceramic particles, helping maintain structural robustness. It also contributes to reducing thermal shrinkage of the coated separator membrane, supporting safer and more reliable battery performance.
Improved conductivity
Providing good electrolyte wettability helps secure efficient liquid penetration and stable separator performance. A good Gurley value allows ion transportation through the separator, while the binder with low resistivity supports smooth ionic flow and contributes to reliable cell operation.
Acrylic based solutions for primer coating of current collectors
Enable high-performance cathodes and accelerate EV mass adoption
Enhancing the interface between the current collector and the active cathode material has become a critical pathway for improving electrode performance. As long‑term durability, conductivity, and mechanical robustness grow in importance, primer layers now play a decisive role in securing stable, high‑efficiency cathodes.
Incellion™ Pr, Arkema’s acrylic-based solution for inside‑the‑cell primer design, provides advanced materials engineered to strengthen the interface between the electroactive material and the current collector.
Primers play a critical role by forming a high-adhesion, conductive layer that ensures robust electrical connection and long-term electrode stability. Designed to address the key challenges of modern lithium-ion batteries, Incellion™ Pr enables more reliable electrodes, improved conductivity, and enhanced overall cell performance—supporting the next generation of EVs and high‑performance energy storage systems.
Why Choose Incellion™ Pr?
More efficient formulation & handling
Compatibility and efficient dispersion of various conductive charges (carbon black, graphite) support optimal electrical pathways, while the suitable rheology profile ensures easy handling during processing. The solution also provides excellent slurry stability, contributing to consistent and reliable electrode manufacturing.
Less is more mechanical integrity
Homogeneous film formation of conductive charges ensures a uniform and efficient electrode structure, supported by excellent peel adhesion to the current collector. The solution provides good adhesion with active material and allows lower dosage of active material binder, contributing to improved performance and material efficiency.
Improved conductivity
Allows higher current conductivity and lowers interfacial resistivity, helping to improve overall electrode efficiency. It also protects aluminum foil from corrosion, while the binder remains electrochemically stable, ensuring reliable performance under demanding operating conditions.
