An important requisite for a good coating process is a homogeneous and stable dispersion of the active and inactive components in the solvent [11-15], The dispersion has to be homogenous for all the components: solid particles in slurry have different sizes, in particular active material particles are usually in the few microns range while carbon black (CB) particles are significantly smaller, less than 100 nm.
