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.

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.

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.

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.

Are advanced battery coatings a trend in the automotive industry?

In conclusion, as the automotive industry undergoes a significant transition towards electric vehicles (EVs), the demand for advanced battery coatings continues to escalate.

Are dielectric coatings a good choice for a battery pack?

With dielectric coatings, Munro at PPG anticipates much greater use of UV-cured materials because they are solids, their application consumes relatively little energy and yields faster throughput when coating filled cells. “This is the next large movement in coatings for the battery pack, along with fire protection considerations.”
