| 摘要 |
The present invention relates to a voltage measurement jig in a three-electrode system to accurately measure a potential difference between the anode and cathode of a jelly-roll. The voltage measurement jig in the three-electrode system comprises an electrically insulating mounting part in which the jelly-roll is inserted; an anode measurement part connected to an anode lead of the jelly-roll, measuring the anode voltage of the jelly-roll, placed on the upper side of the mounting part, and electrically connected to a voltage measurement device; a cathode management part connected to a cathode lead of the jelly-roll, measuring the cathode voltage of the jelly-roll, placed at the lower side of the mounting part, and electrically connected to the voltage device; and a reference electrode measurement part electrically connected to a reference electrode, measuring the voltage of the reference electrode, electrically connected to the voltage measurement device, and placed at the lower side or the upper side of the mounting part. |
