摘要
The present technology relates to: an electrochemical element which comprises a separator having through-holes formed therein, a through-hole cover material, and a spacer; and a method for using the electrochemical element to evaluate the safety of an energy storage device by means of an internal short circuit. An energy storage device including the electrochemical element according to the present invention is characterized in that: the energy storage device can be restored, after an internal short circuit evaluation test, to a state in which a short circuit has not occurred; and a repeat test and evaluation can be carried out without disassembly and reassembly.
