Abstract
An apparatus of testing an all-solid state secondary battery by nail penetration includes a pressurizing unit pressurizing a battery cell, a penetrating member inserted into a through-hole provided in the pressurizing unit to pass through the battery cell, and an auxiliary pressing unit disposed between the pressurizing unit and the battery cell and transferring pressure applied by the pressurizing unit to the battery cell. The auxiliary pressing unit is disposed between the through-hole and the battery cell in a form to block the through-hole.
