This disclosure is generally directed to inks used to create fine features for electrodes, batteries, solar cells, etc. More particularly, in embodiments, this disclosure is directed to compositions of easily flowable inks that result in reduced clogging when applying the ink to a substrate to create fine features. The inks are characterized by their rheological properties, particularly with respect to viscosity and flowability. Flowability is measured by measuring the quantity of ink which will flow through a 400 mesh screen. Also disclosed are methods of applying the easily flowable inks. The inks are applied using extrusion processes, particularly coextrusion. Coextrusion of the inks allows fine features having high aspect ratios to be formed without clogging of the coextrusion printhead.
