This application provides example segment membranes, example battery combinations, and example electrical devices. One example segment membrane includes a conductive layer, a first insulation layer, and a second insulation layer that are disposed in a laminated manner, where the conductive layer is located between the first insulation layer and the second insulation layer. The conductive layer includes 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, and the first insulation layer is disposed on a surface that is of the first conductive part and that is away from the second conductive part. The second insulation layer is a second frame structure, and the second insulation layer is disposed on a surface that is of the second conductive part and that is away from the first conductive part.

Segment membrane, battery combination, and electrical device

An electrode material layer includes an electrode active material and graphene of a sheet-like structure, a surface of the graphene is modified with magnetic response nanodots, and in the graphene, more than 50% of the graphene is arranged at an angle of 45&#xb0; to 90&#xb0; with respect to a surface, of the current collector, on which the electrode material layer is disposed, to form a heat conduction path having a specific orientation.
