Acrylic based solutions for separator coating
Reinforce safety and stability for high‑performance lithium‑Ion batteries
The separator plays the role of a safety insulating barrier between the electrodes. It is usually functionalized to provide thermal stability and adhesion properties to ensure durable and high-performance cells operations.
Incellion™ Sp solutions for battery separator are used as a binder for the ceramic layer and as a co-binder for the adhesive layer, to develop formulations that enhance mechanical and thermal properties without compromising electrochemical performance.
Why Choose Incellion™ Sp?
More efficient formulation & handling
Their high compatibility with alumina and boehmite allows efficient formulation, with a rheology profile and slurry stability enabling reliable coating of the ceramic layer.
Better mechanical and thermal properties
The binder allows an effective ceramic coating with high peel‑adhesion properties while maintaining the structural robustness of the system to reduce thermal shrinkage at higher temperatures. This enables safer and high‑performance battery design.
Maintain electrochemical performance
To maintain high electrochemical performance it is key to rely on binders which provide good electrolyte wettability and maintain a certain level of permeability to allow the ion transfer through the separator system.
Adhesive layer
Acrylic-based binders are used in synergistic combination with Kynar® PVDF to improve bonding of the adhesive layer with ceramic surface, help to disperse PVDF particles and provide mechanical flexibility.
Acrylic based solutions for primer coating of current collectors
Enable high-performance electrodes
Enhancing the interface between the current collector and the electrodes has become a critical pathway to improve battery performance. As long‑term durability, conductivity, and mechanical robustness grow in importance, coated collectors now play a decisive role.
Incellion™ Pr binders provide advanced solutions to design coated collector with higher adhesion performance between collector and electrode while improving electrochemical properties. Incellion™ Pr binder plays a critical role in LFP batteries, where coated collectors are mandatory on the cathode. Coated collectors are key enabler for fast-charging battery cells.
Why Choose Incellion™ Pr?
More efficient formulation & handling
Compatibility and efficient dispersion of various conductive charges support optimal electrical pathways, while the suitable rheology profile ensures easy handling during processing. Incellion™ Pr also provides excellent slurry stability, contributing to consistent and reliable electrode manufacturing.
Mechanical integrity
Homogeneous film formation of conductive charges ensures a uniform and efficient electrode structure, supported by excellent peel-adhesion to the current collector. Incellion™ Pr provides good adhesion with active material and allows lower dosage of active material binder or a thicker electrode for higher energy density.
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.
