    摘要: The present invention provides a charge storage device, comprising a pair of electrodes, each electrode being operable to store electric charge and having a respective capacitance CP, CN that is different to the other, with the ratio of the capacitances CP/CN being greater than 1. In exemplary embodiments, the charge storage device may be an asymmetrical supercapacitor, which is operable to provide an enhanced energy capacity by increasing the cell voltage through unequalising the electrode capacitance. Hence, by increasing the CP/CN ratio an improved power capability can be achieved over conventional devices, while offering a simple and low cost manufacturing strategy. The present invention has particular application with cameras, electric vehicles, elevators, renewable energy stores, fuel cells, batteries and many forms of electronic devices.

    摘要: A specific embodiment of the present invention is a process for continuously producing a porous solid film of spacer-modified nano graphene platelets for supercapacitor electrode applications. This process comprises: (a) dissolving a precursor material in a solvent to form a precursor solution and dispersing multiple nano graphene platelets into the solution to form a suspension; (b) continuously delivering and forming the suspension into a layer of solid film composed of precursor material-coated graphene platelets overlapping one another, and removing the solvent from the solid film (e.g., analogous to a paper-making, mat-making, or web-making procedure); (c) continuously converting the precursor material into nodules bonded to surfaces of graphene platelets to form a porous solid film composed of spacer-modified graphene platelets; and (d) continuously collecting the porous solid film on a collector (e.g., a winding roller). The roll of porous solid film (mat, paper, or web) can then be cut into pieces for used as supercapacitor electrodes.
