DEVICE OF EVALUATING SEPARATOR SAFETY AND METHOD OF EVALUATING THE SAME

原文（中国語）

A device for evaluating the safety of a separator, including: a pressing unit to apply a pressure to a test sample including a first electrode, a standardized foreign matter, a separator, and a second electrode; an insulation breakdown measurement unit to apply a voltage to the first electrode and the second electrode to measure a breakdown voltage; and a controller to control the pressing unit and the insulation breakdown measurement unit, and determine the safety of the separator based on the measured breakdown voltage. In the test sample, the first electrode, the standardized foreign matter, the separator, and the second electrode are sequentially stacked, and the standardized foreign matter is located between the first electrode and the separator.
