FIELD: chemical sources electric energy. SUBSTANCE: device includes tape-pulling mechanism, screw extruder coupled through hole to extrusion head having through slot to let pass base with calibrating outlet section, slot channels to feed material of electrode on to base arranged in symmetry on both sides of slot for passing of base and system of transport channels. Ratio of length of calibrating section of slot to clearance equals 5:50. Ratio of value of clearance of slot channels to value of clearance of slot in calibrating section of slot for passing of base amounts to 3.5-15.0. Extrusion head has two holes for coupling of two extruders and two slot channels to feed electrode material on to base. Additional slot channel and hole for coupling of extruder can be made between pair of these slot channels and outlet. EFFECT: uniformed density of material of electrodes, capability for application of several layers of material of different compositions. 3 cl, 8 dwg
