Abstract: Disclosed is an electronic device including a display module and a camera module. The display module includes a first substrate and a second substrate stacked with each other, and a routing structure arranged on a surface of one side of the second substrate facing towards the first substrate, and provided with a first light-passing hole. The camera module includes a camera body and a light-shielding layer arranged on a surface of one side of the first substrate away from the second substrate and provided with a light inlet hole and a second light-passing hole. The first light-passing hole, the second light-passing hole, and the light inlet hole are arranged in an optical axis direction of the camera module. An orthographic projection of the first light-passing hole and the second light-passing hole on a surface perpendicular to the optical axis direction fall within an orthographic projection of the light inlet hole.

Abstract: The present invention provides a graphene coating-modified electrode plate for lithium secondary battery, characterized in that, the electrode plate comprises a current collector foil, graphene layers coated on both surfaces of the current collector foil, and electrode active material layers coated on the graphene layers. A graphene coating-modified electrode plate for lithium secondary battery according to the present invention comprises a current collector foil, graphene layers coated on both surfaces of the current collector foil, and electrode active material layers coated on the graphene layers. The graphene-modified electrode plate for lithium secondary battery thus obtained increases the electrical conductivity and dissipation functions of the electrode plate due to the better electrical conductivity and thermal conductivity of graphene. The present invention further provides a method for producing a graphene coating-modified electrode plate for lithium secondary battery.
