  • Publication number: 20210190874
    Abstract: A jig pressing-type pressing short-circuiting inspection method includes 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 method includes inserting the plurality of battery cells in an active jig; pressing the active jig; and inspecting electric current of the battery cells. The inspection method permits detection of a low-voltage defect of a battery cell in a pre-aging state, which shows a high voltage regulation per capacity, thus greatly reducing the inspection time, and enabling simultaneous inspection of a plurality of battery cells. In addition, a micro-defect occurring in a stack-folding type battery cell can be accurately detected, which is difficult to be detected by the conventional inspection method.
