DEVICE FOR TESTING SHORT CIRCUIT OF SECONDARY BATTERY

摘要

This device for testing a short circuit of a secondary battery comprises a metal rod-shaped member (100) that pierces one side of the secondary battery, forming a through-hole therein. Said rod-shaped member (100) is designed so as to have a cutting section (200) that has corners (101a, 102a) on the outer edge of a cross-section thereof and that creates cracks in the outer edge of a through-hole in an electrode bundle.
