Customer ServiceAs a step in dry processing, dry coating in battery cell production is an innovative process that is revolutionizing traditional electrode production. This approach addresses the issue of how to process dry starting materials into battery electrodes in an efficient, resource-saving and sustainable manner without the use of solvents.
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.
Before the material can be processed into electrodes on a dry coating system, it requires the upstream production step of dry mixing. The elimination of solvents in the mixing process will change the processing of the raw materials and the requirements for the plant technology.
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.
Battery cell production therefore plays a key role, since it determines the cost and longevity of the entire electric vehicle. Dürr provides the coating technology for battery electrodes from a single source – and much more. In Europe, 460,000 electric cars were registered in 2020.
