SECONDARY BATTERY STATIC PRESSURE JIG AND SECONDARY CELL INTERNAL PRESSURE CONTROL METHOD USING THE SAME

摘要

The secondary battery positive pressure jig according to an embodiment of the present invention is disposed on at least one of a support member disposed on both sides of a battery cell to support the battery cell, and a surface in which the support member and the battery cell are in contact, and the A piezoelectric element for measuring the pressure applied to the battery cell, and a control unit for adjusting the volume of the piezoelectric element according to the pressure measured by the piezoelectric element, wherein the volume of the piezoelectric element according to the volume change of the battery cell and the pressure applied to the battery cell from the support member by the volume change of the piezoelectric element becomes a positive pressure.
