CONTINUOUS SCREW MIXING AND EXTRUDING OF AN ELECTRODE PASTE

摘要

An apparatus (21) for continuous intimate mixing of materials for forming a cathode of a battery includes a blending portion (23), in which an active cathodic material (25) and a conductive filler material (27) are blended together. The blended active cathodic material (25) and conductive filler material (27) are mixed, in a mixing portion (31), with an electrolyte material (35) such that intimate mixing between the active cathodic material (25), the conductive filler material (27), and the electrolyte material (35) occurs. The mixture of active cathodic material (25), conductive filler material (27), and electrolyte material (35) is pressurized to a constant pressure at the outlet (43) of the apparatus.
