Abstract
The present disclosure relates to a system for determining the shut-down temperature and melt-down temperature of a separator. The system includes a jig having a through-hole, a heating unit, a temperature sensor, a controlling unit and an air permeability-determining unit. In this manner, it is possible to provide a novel system for determining the shut-down temperature and melt-down temperature of a separator by using the air permeability (Gurly value) of the separator.
