| 摘要 |
The present invention relates to an apparatus and a method to test degradation which simultaneously tests thermal resistance, electrochemical degradation, and mechanical deformation. According to the present invention, the apparatus (100) to test degradation comprises: a chamber (110) having an accommodation space (115) disposed therein, wherein a solvent (S) is accommodated in the accommodation space (115); a support means (120) arranged in the accommodation space (115), supporting a test sample (T), and providing the test sample (T) with a tensile force; a voltage supply means (130) to apply a voltage to the solvent (S) and the test sample (T); a heater (140) to heat the solvent (S); a first sensor to sense a current flowing through the test sample (T); a second sensor to sense a temperature in the accommodation space (115); and a control unit (150) to control the voltage supply means (130) and the heater (140). |
