Abstract

A welding horn, an ultrasonic welding device comprising the welding horn, a battery cell processed by the ultrasonic welding device, a battery comprising the battery cell, and an electric device comprising the battery. A welding end (401) of the welding horn (400) is provided with welding teeth (5) and tooth grooves (6), the welding teeth are divided by the tooth grooves into a plurality of tooth portions (51) spaced apart, and the tooth area ratio of the welding end is greater than or equal to 40%. The arrangement of the welding teeth on the welding horn increases the area ratio of a compaction region in ultrasonic welding, so that more contour lines of laser welding imprints fall within the compaction region, mitigating the problem of thermal cracks along the contours of the laser welding imprints.
