The present application discloses an insulating adhesive, a tab assembly, a battery cell, and an electric device. The insulating adhesive comprises a surface layer. The surface layer has a melt flow index of 4-20 g/10 min at 230ºC under a load of 2.16 kg and a number-average molecular weight of 10000-130000 g/mol. By setting the melt flow index of the surface layer at 230ºC under a load of 2.16 kg and the number-average molecular weight of the surface layer, the flowability of the surface layer after being melted is improved, thereby enlarging overflowed adhesive lumps formed after the surface layer is melted, reducing liquid leakage caused by voids and/or bubbles, and enhancing sealing peel strength and sealing reliability of the battery cell under room-temperature working conditions; in addition, the improved flowability of the surface layer enables the rapid formation of pressure relief channels when the battery cell undergoes swelling, thereby improving heat dissipation efficiency and thus enhancing the safety performance of the battery cell.
