ABSTRACT:
In the manufacture of a battery cell, a shear thinning cathode material that has been mixed to a homogeneous state is transported to an extrusion opening while being subjected to a non-decreasing shear stress. The shear thinning cathode material is extruded onto a conductive substrate material at a constant rate. An electrolyte material is applied over the shear thinning cathode material, and an anode material is applied over the electrolyte material.
