Method for manufacturing electrode, classification system, and, electrode material

A classification system for performing dry classification of an electrode material, the classification system comprising:

• a classifier;
• and
• a detector, wherein:
• the classifier includes a mesh screen, a blade, and a motor;
• the mesh screen has a tubular outer shape;
• the mesh screen is electrically insulating;
• the mesh screen is configured to separate coarse particles from the electrode material;
• the blade is configured to press the electrode material against the mesh screen;
• the motor is configured to rotate the blade along an inner peripheral surface of the mesh screen;
• the detector is configured to detect breakage of the mesh screen by monitoring torque of the motor;
• and
• the detector is configured to determine that the breakage has occurred when the torque falls out of a reference range, wherein the reference range is a range used to determine whether the classifier should be stopped.
