JIG PRESSING-TYPE PRESSING SHORT-CIRCUITING INSPECTION METHOD

A jig pressing-type pressing short-circuiting inspection method of the present invention comprises the steps of: pre-aging battery cells, each of which is manufactured by inserting an electrode assembly in a battery container, injecting an electrolyte into the battery container, and sealing the battery container, the electrode assembly including a positive electrode, a negative electrode, and a separation film laminated on each other, the separation film being disposed between the positive electrode and the negative electrode (S100); inserting the plurality of battery cells in an active jig (S200); pressing the active jig (S300); and inspecting electric current of the battery cells (S400). The pressing short-circuiting inspection method according to the present invention enables inspection of a low-voltage defect of a battery cell in a pre-aging state, which shows a high voltage regulation per capacity, and thus can greatly reduce the inspection time. In addition, the present invention enables a micro-defect occurring in a stack-folding type battery cell, which is difficult to be detected by the conventional inspection method, to be accurately detected, and enables simultaneous inspection of a plurality of battery cells by using an active jig.
