Li-ion battery cell manufacturing process The manufacturing process of a lithium-ion cell is a complex matter. Superficially, it often seems to be quickly understood, but the deeper one delves into the matter, the more complex it becomes. Sooner or later you get to a point where you understand that there are hundreds of ways to make a battery cell. On the one hand, this is
The coating process of lithium batteries is a key production technology that involves evenly applying positive and negative electrode slurries onto substrates (such as aluminum foil or copper foil) to form a special functional film layer.

Electrode Manufacturing: Coating 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. What is Coating Process?
It is to disperse binders contained in the intermediate goods evenly onto electrodes for uniform performance and longer life of the battery. Taking up 18% of the entire process, the coating is highly important because most of battery design parameters are determined in this step.
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.
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.
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.”
