Abstract
The present invention relates to a method and system for evaluating insulation and lithium ion conductivity characteristics of a separator for an electrochemical device, in which insulation and lithium ion conductivity characteristics are evaluated while a separator-containing measurement object to be tested and an electrochemical device are made to face each other, and thus, the insulation and lithium ion conductivity characteristics of the separator can be evaluated by reflecting temperature and pressure changes and the like according to the actual operation state of the electrochemical device.
