Abstract
A supercapacitor including a gel electrolyte and two electrodes having a substrate, date stone activated carbon, a conductive carbon compound different from the date stone activated carbon, and a binding compound. A mixture of the date stone activated carbon, the conductive carbon compound, and the binding compound partially coats a surface of the substrate. The two electrodes are assembled in a symmetrical layered configuration with the surfaces coated with the mixture facing each other. The gel electrolyte is present between the surfaces coated with the mixture to form the supercapacitor. The gel electrolyte is a mixture of HSO, polyvinyl alcohol, and anthraquinone. Particles of the date stone activated carbon have a nanosheet morphology, and the nanosheets are stacked on top of each other to form a hierarchical structure.
