METHOD FOR MEASURING INSULATION RESISTANCE OF RECHARGEABLE BATTERY CELL

WIPO Patent Application WO/2019/164300

A1

The present invention relates to a method for measuring the insulation resistance of a rechargeable battery cell, and more specifically, to a method for measuring the insulation resistance of a rechargeable battery cell, whereby the insulation resistance of a pouch-type rechargeable battery cell is measured in order to sort out good-quality pouch-type rechargeable battery cells. Disclosed is a method for measuring the insulation resistance of a rechargeable battery cell (40), the rechargeable battery cell (40) comprising: an electrode assembly (10) having first electrode sheets (12) and second electrode sheets (14) alternately laminated, and having separators (16) respectively positioned between the first electrode sheets (12) and the second electrode sheets (14); a pouch (20) for sealing the electrode assembly (10); and a lead tab (30) connected to the electrode assembly (10) and protruding to the outside of the pouch (20).
