After the mixing process where the cathode and anode materials are mixed, the next step of battery electrode manufacturing is coating. In this process, the cathode and anode slurries, intermediate goods produced in the mixing process, are applied onto aluminum and copper foils respectively.
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.
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.
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.
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.”
The recommended thickness for a battery coating is near 25 microns. However, thinner coatings may require smaller wet thickness minimums. All the methods allow for a maximum web thickness over 1.0 mm.
