  "textContent": "An inspection method for a low-voltage defect of a lithium secondary battery includes performing a microcurrent charging/discharging process having N charging/discharging sections, N being an integer of 2 or more, and for each charging/discharging section, applying a microcurrent to the lithium secondary battery; measuring a change in voltage of the lithium secondary battery before and after each charging/discharging section; and screening for the low-voltage defect of the lithium secondary battery based on the measured change in voltage. The lithium secondary battery having the low-voltage defect is not shipped. The microcurrent for each charging/discharging section is at a current rate of 0.000001 C to 0.0001 C.",
