Polymer Coatings for increased Performance of Solid-State Batteries
Solid-state batteries with inorganic solid electrolytes contain interfaces in the anode and cathode at which electrochemical degradation can cause the cell performance to decrease. Interlayers and protective coatings are applied to improve the stability of the interfaces. Using polymers as interlayers is expected to be beneficial as the mechanical properties of the polymers can be adapted continuously over a wide range by varying the polymer composition. For example, a conformal polymer coating was applied to vapor grown carbon fibers (VGCF) by Nina Herrmann and Dr. Sudeshna Sen (see SEM images). The group of Felix Richter develops polymers as coatings, interlayers and binders for solid-state batteries with inorganic solid electrolytes.
