METHOD FOR MANUFACTURING CARBON ELECTRODE MATERIAL

摘要

A method of extruding a dry mixture includes providing mixing materials to a twin screw extruder. The mixing materials are substantially dry and may include a substantially unfibrillated binder and a carbon material. The method includes extruding the mixing materials via a twin screw extruder to form an extruded mixture that is substantially dry. In one embodiment, the substantially dry mixture exiting the extruder may be further processed to form an electrode material, such as by a calendaring step.
