Problems solved by technology

[0005] This external integration method, first of all, requires secondary packaging of the independent graphene supercapacitor, that is, packaging the electronic components of the graphene supercapacitor, and welding the graphene supercapacitor on the PCB after the secondary packaging. Higher, and due to the secondary packaging, the graphene supercapacitor occupies too much space, the integration of the energy storage system is low, and the space utilization rate is low

Abstract

The invention discloses a graphene supercapacitor and a preparation method thereof, and an energy storage system. The method comprises two pads are prepared on a PCB and serve as first and second current collector substrates of the graphene supercapacitor; a graphite oxide solution is dropped in a to-be-dropped areas formed on the first and second current collector substrates; laser engraving reduction is carried out on graphite oxide films formed by drying and molding the graphite oxide solution to form first and second patterned graphene electrodes; and the first and second graphene electrodes are packaged by filling an electrolyte to form the graphene supercapacitor. According to the scheme, the pads on the circuit board serve as the current collector substrates, the preparation technology of the graphene supercapacitor is optimized, the procedure of welding is omitted, and the integrated level of the PCB is improved.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to a preparation method of a graphene supercapacitor, a graphene supercapacitor and an energy storage system. Background technique [0002] At present, energy storage devices generally used in energy storage circuits are supercapacitors, lithium batteries, lead-acid batteries, etc. And usually the supercapacitor is used as the primary energy storage unit, and the lithium battery is used as the secondary energy storage unit. The uniqueness of supercapacitors in the process of energy storage and release is not only reflected in the high pulse rate charge and discharge process, but also has the advantages of high energy and high specific power, that is, the charge and discharge time is only tens of seconds, and its power density is comparable to that of batteries. Compared with , 10 to 100 times higher. [0003] Since graphene is a carbon molecule composed of carbon atoms arrange...
