Bottom surface of movingpart of the press equipment is made of Nitrile rubber or Acryl, which is put onthe 10 mm x 10 mm stainless steel shaft. The detail of pressing jigs shall beshown in Figure 2. Nitrile rubber bottom surface is for cylindrical cell test.For prismatic test 5 mm x 5 mm (2 mm thickness) Acryl is put on the Nitrilerubber. The fixture is moved down at the speed of 0,1 mm/s monitoring the cellvoltage. When voltage drop caused by the internal short circuit is detected,stop descent immediately and keep pressing jig in the position for 30 s andthen release the pressure. Voltage is monitored m-ore than 100 times per secondand if voltage is dropped more than 50 m V compare to the initial voltage, itis defined to internal short circuit has occurred. If the pressure reaches 800N for cylindrical cell and 400 N for prismatic cell, stop descent immediatelyand then keep in the position.
