SEALANT, CELL, BATTERY, AND ELECTRICAL DEVICE

A sealant. The sealant comprises a first sealant layer and second sealant layers which are continuously arranged in a first direction, the first direction being perpendicular to the thickness direction of the first sealant layer. The melting point of the first sealant layer is lower than that of the second sealant layer, wherein the difference between the melting points of the first sealant layer and the second sealant layer is 15°C to 55°C. The present application further provides a cell, a battery, and an electrical device which are provided with the sealant. The sealant is used for being connected between a tab and a package, so as to improve the sealing performance and the insulating performance of a connecting area between the tab and the package. When the sealant is used in the cell, if the temperature of the cell is abnormally increased and falls within a melting point range of the first sealant layer, the first sealant layer will melt to reduce the packaging strength of the connecting area between the
