摘要： Systems and methods are provided for a slurry for coating an electrode structure. In one example, a method may include dispersing, by mixing at one or both of a high shear and a low shear, a solid ionically conductive polymer material in at least a first portion of a solvent to form a suspension, then dispersing, by mixing at the one or both of the high shear and the low shear, one or more additives in the suspension, and then mixing, at the one or both of the high shear and the low shear, a second portion of the solvent with the suspension to form a slurry. As such, the slurry including the solid ionically conductive polymer material may be applied as a coating in a solid-state battery cell, which may reduce resistance to Li-ion transport and improve mechanical stability relative to a conventional solid-state battery cell.
