  • the electrode cutting and dosing device 120 for a secondary battery changes the cutting, acceleration and closing manner of the electrode by the cutting portion 121 so that the cutting portion 121 performs only cutting of the electrode,
  • the amount of acceleration and the amount of deceleration of the cutout portion 121 are reduced in such a manner that the feed roller portion 124 continuously accelerates and feeds the cut electrode, thereby reducing the mechanical load and improving the mechanical load stability, Thereby reducing the number of steps on the cycle and improving the operation speed to improve the productivity.
