1. A segment membrane for electrical connection and isolation between electrode assemblies in a battery combination, wherein the segment membrane comprises a conductive layer, a first insulation layer, and a second insulation layer that are disposed in a laminated manner, wherein the conductive layer is located between the first insulation layer and the second insulation layer, and wherein:
the conductive layer comprises a first conductive part and a second conductive part that are disposed in a laminated manner and electrically connected;
the first insulation layer is a first frame structure disposed on a surface of the first conductive part and away from the second conductive part;
the second insulation layer is a second frame structure disposed on a surface of the second conductive part and away from the first conductive part;
the battery combination comprises a package layer;
the segment membrane is configured to separate the package layer into sealing chambers; and
the segment membrane further comprising a third conductive part, wherein the third conductive part is respectively in electrical connection with the first conductive part and the second conductive part, and the third conductive part extends outside the sealing chambers.
