Technology Outline (Process Description)

Predominantly supercapacitors (SC) are beneficial energy storage devices because of their exceedingly competent charge storage capability, cyclic stability, power density, and rate capability. But the commercialization of SCs is majorly hindered by their low energy density. In view of realizing the high energy and power density of the SC, enhancing the reaction kinetics by increasing the material’s characteristic property, selecting suitable electrode materials, and modifying the electrode and elec- trolyte architecture was considered potent. In this regard, structurally engineered SC electrodes with a three-dimensional porous morphology were possibly found to enhance the electrochemical performance, due to their increased surface area, and highly coordinating 3D skeleton network, which interlinks the active material network to provide better conductivity. Besides, their reliable pore channels allow for faster ion diffusion which improves the performance of the electrode greatly. A 3D architecture current collector was prepared via simple dynamic hydrogen bubble template (DHBT) process. A novel electrode made up of binary metallic oxide surrounded with carbon matrix and metal sulphide is designed as the electrode materials that substantially more active and efficient. Binder free 3D-C-NiCo2O4/Ni nanoplate growth like the cactus plant was synthesized by hydrothermal route and followed by carbonization process. A vapour phase approach was utilized to fabricate dendrimer growth of 3D-Fe3S4@NiCo/SS nanostructure. Supercapattery device delivered a maximum energy density of 50 Wh kg^-1 and power density of 8100 W kg^-1
