Electrode coatings

When manufacturing electrodes using wet-chemical methods, process steps include adapting existing production processes to pastes, developing new electrode materials and producing the electrodes themselves (by means of screen printing, spraying, scraping and gravure printing). To optimize energy storage systems, we evaluate new electrode materials, apply structures and adjust parameters such as layer thickness and conductivity. The coating methods developed are implemented to manufacture new electrodes under realistic conditions on our laboratory to roll-to-roll pilot plant. The plant is capable of an adequate range of coating widths and geometry and can be used to produce flexible small series.

In the field of fabricated layers, particularly four-point measurements give information about electrical resistance. We use layer thickness distribution to analyze surface homogeneity across the complete coating width.
