Advantages and Disadvantages of Coating Methods

AIMCAL R2R Presentation Preview

In an era when battery technology is advancing at record pace it is important to be sure that battery manufacturing is capable of keeping up. In many cases the accuracy and precision of the coated electrode is what can make or break a new technology. For example, it may be imperative to control the mass of anode or cathode loading to within +/-2 percent or better. Also, with the introduction of new, exotic, and expensive raw materials, it will be important to minimize waste from excess coating or exposure to contaminants. Different type of current collectors used as substrates for electrodes may present difficulties in the coating process. All coating methods are not alike. The electrode coating method should be evaluated to determine whether it can produce electrodes that conform to these high standards.

For instance, can your current coating method produce an electrode with a cross web loading uniformity of better than +/- 2 percent? It may be possible at 100mg/cm2 loading but can it produce that accuracy at 25mg/cm2.

Is the electrode slurry exposed to environmental contaminants during the coating process? This can prevent the leftover fluid from being recycled or reused.

Is solvent allowed to evaporate from the slurry vessel during the coating process? This can cause variation in the slurry make-up which will influence the downstream quality of the coated electrode.

At the AIMCAL R2R Conference, Scott Zwierlein, coating process engineer at Frontier, a Delta ModTech company will be presenting further on this topic. His presentation will address the advantages and disadvantages of a number of coating methods to give you the tools to evaluate which process will best suit your technology.
