LEAK INSPECTION APPARATUS AND METHOD FOR SECONDARY BATTERY CELL

Proposed are a leak inspection apparatus for secondary battery cells and a leak inspection method for secondary battery cells and, more particularly, a leak inspection apparatus for secondary battery cells and a leak inspection method for secondary battery cells to determine whether leakage occurs in a secondary battery cell being inspected by creating a pressure difference between the inside of a casing of the secondary battery cell accommodated in a chamber part and the internal space of the chamber part and detecting swelling of the secondary battery cell.
