Abstract: A graphene busbar includes a graphene core formed by compressing graphene powder at high pressure. The busbar is insulated with an insulating and reinforcing material, which may be applied to the graphene core before or after compression. The busbar may also include contacts formed of an electrically conductive material, such as copper, that are connected to the graphene core.

Abstract: A structured battery having a battery core disposed between two carbon fiber layers. The battery core includes one or more layers of graphene battery sheets configured to store electricity. The structured battery also includes a honeycomb layer configured to transfer heat from the one or more layers of graphene battery sheets to the carbon fiber layers. The structured battery can be used as a structural component such as components of an electric vehicles, components of a building, or components of an appliance.

Abstract: A supercapacitor having multiple graphene layers that are separated by separator layers.
