Why do battery cells need a coating?

Inside the cells, coatings are applied to enhance mechanical and thermal stability; particle coatings to improve the cycle life of active materials and conductivity of the current collector foils, to reduce cell resistance and improve adhesion of the active material on these foils, explains Dr. Tobias Knecht, battery cells specialist at Henkel.

Are battery coatings a problem?

According to Henkel’s Dr Knecht, the principal problems in the realm of electrical protection of key battery components include ensuring the coating’s own ability to be stable at extraordinary high voltages, along with typically challenging lifetime requirements.

What are the different types of battery coatings?

The company is working on a variety of different products ranging from fire resistant coatings of battery lids, metal pre-treatments that suppress corrosion of battery housings, dielectric coatings for that are typically applied on battery cans and conductive coatings of current collector foils.

Do battery manufacturers need electrode coating?

Now, also battery manufacturers can order the necessary technology for electrode coating from a single source: from electrode coating through to exhaust-air purification and solvent recovery. Most plants currently used by battery manufacturers coat one side of the electrode foil first before moving on to the other.

Can polymer composite materials cause interference in a car battery?

Polymer composite materials increasingly used in vehicle and battery structures are often effectively transparent to electromagnetic radiation. That potentially causes interference problems with electronics in the battery such as the battery management system (BMS), general vehicle management and safety systems.

What is a conductive coating?

Conductive coatings play a vital role in enhancing battery performance. These coatings, typically water or solvent-based dispersions of conductive fillers, resins, and additives, are applied to current collector foils to increase surface roughness and improve the interaction between the current collector and the active material layer.

Simultaneous two-sided electrode coating and drying

The usual process only allows coating the foil one side at a time. This production set up requires two separate passes through the same coating line, but a more efficient method is to coat both sides in a single pass. Two ways to do this include: 1) with a sequential or tandem coating system or 2) with simultaneous two-sided coating.
