Abstract

A battery cell (12), a battery (100) and an electric device, which belong to the technical field of batteries. The battery cell (12) comprises a casing (121), a first insulating member (125) and a second insulating member (126), wherein the casing (121) comprises a first wall (1213), a second wall (1214) and a side wall (1215); in the direction of the thickness of the first wall (1213), the second wall (1214) and the first wall (1213) are arranged opposite each other; the side wall (1215) is arranged around the first wall (1213) and the second wall (1214); and the first wall (1213) has first edges (12131) and second edges (12132), which are adjacent to one another. The first insulating member (125) covers an outer surface of the first wall (1213). The second insulating member (126) comprises a body portion (1260), first flange portions (1261) and second flange portions (1262), wherein the body portion (1260) covers an outer surface of the side wall (1215); the first flange portions (1261) and the second flange portions (1262) are arranged on the outer surface of the first wall (1213); the first flange portions (1261) are arranged along the first edges (12131); and the second flange portions (1262) are arranged along the second edges (12132). The first insulating member (125) covers at least part of each first flange portion (1261) and at least part of each second flange portion (1262). The first insulating member (125) covers at least part of each first flange portion (1261) and at least part of each second flange portion (1262) to improve the reliability of the battery cell (12).
