  "textContent": "The present application relates to a battery cell, a battery, and an electrical apparatus, the battery cell includes: a case, an outer surface thereof away from the interior of the battery cell is clad with a first insulating layer; an end cap assembly, which is disposed at an end portion of the case along the length direction of the battery cell; and an end cap patch, which is attached to a surface of the end cap assembly away from the interior of the battery cell; wherein the end cap patch is adhered with a second insulating layer, and the second insulating layer is at least partially folded to the case and is connected with the first insulating layer. In the battery cell of the present application, before the end cap patch is attached to the end cap assembly, the second insulating layer is first adhered to the end cap patch, so that the second insulating layer and the first insulating layer can be completely adhered to the case, the adhesion is firm, and no warping occurs at the folded position, so as to prevent the end cap patch from falling off, and reduce the risk of short circuit of the battery.",
