Abstract

The invention discloses a stacked supercapacitor with any shape on the same substrate and a preparation method thereof. The capacitor is sequentially integrated with a first layer of electrode film / second layer of diaphragm / third layer of electrode film / solid electrolyte on a substrate Stacked supercapacitors of any shape. The preparation method is to spray-coat the lower electrode film layer with any shape on the same substrate, then spray-coat the lower electrode film to manufacture the graphene oxide diaphragm layer, and then manufacture the upper electrode film layer on the diaphragm layer to obtain a supercapacitor with a stacked structure. . The arbitrary-shape stacked supercapacitor manufactured by the present invention can realize controllable shape and large-scale production, can be effectively compatible and integrated with different types of flexible, portable, and wearable electronic devices, and has broad market application prospects.

Description

technical field [0001] The invention belongs to the field of manufacturing supercapacitors, in particular to a stacked supercapacitor with any shape on the same substrate and a preparation method thereof. Background technique [0002] Traditional stacked supercapacitors are stacked in the form of current collector (substrate) / positive electrode / diaphragm / negative electrode / current collector (substrate). The manufacture of stacked supercapacitors with this structure takes a long time, the process is complicated, and its structure involves two substrates; the current collector and electrode materials are not integrated, resulting in the large volume of traditional stacked supercapacitors, which is not conducive to its applications in miniaturized integrated circuits. [0003] The rapid development of light, thin, and bendable electronic devices in various shapes has greatly stimulated the demand for new energy storage devices. Current energy storage devices, such as lithium ...
