PROBLEM TO BE SOLVED: To produce a carbon electrode material containing polytetrafluoroethylene not fiberized.SOLUTION: A method of producing a carbon electrode material has processes: for forming a carbon electrode batch material free from fiber, by mixing active carbon, polytetrafluoroethylene not fiberized, and a medium substantially containing water; for creating an extrusion material not having a substantial aggregation of fiberized polytetrafluoroethylene, by passing the batch material through a biaxial extruder; and for creating a calendered material by calendering the extrusion material.SELECTED DRAWING: Figure 1 |
