“…Graphene‐based composite materials, especially those with heterostructure, such as graphene/carbon, a combination of two EDLC type materials which expand the gap between RGO sheets and enlarge the surface area between active materials and electrolyte shows both higher capacitance and faster ion diffusion rate, comparing with bulk graphene/RGO. Apart from RGO/MWCNT based MSC reported by Mao et al, carbide derived carbon (CDC) is also reported as a function of nanospacer between RGO sheets in SCs application by Alhabeb et al The as‐reported RGO/CDC free standing film was prepared via vacuum filtration method and exhibited superior capacitance of 200 F g −1 at a high scan rate of 100 mV s −1 as well as 94% capacitance retention rate after 10 000 cycles at 10 A g −1 . Such a hybrid electrode may be fabricated in the MSCs with mask‐assisted method or laser scribing techniques.…”

The continuous development of integrated electronics such as maintenance‐free biosensors, remote and mobile environmental sensors, wearable personal electronics, nanorobotics etc. and their continued miniaturization has led to an increasing demand for miniaturized energy storage units. Microsupercapacitors with graphene electrodes hold great promise as miniaturized, integrated power sources thanks to their fast charge/discharge rates, superior power performance, and long cycling stability. In addition, planar interdigitated electrodes also have the capability to reduce ion diffusion distances leading to a greatly improved electrochemical performance. Either as standalone power sources or complementing energy harvesting units, it is expected that graphene‐based microsupercapacitors will play a key role as miniaturized power sources in electronic microsystems. This review highlights the recent development, challenges, and perspectives in this area, with an emphasis on the link between material and geometry design of planar graphene‐based electrodes and their electrochemical performance and integrability.

[44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] As witnessed, raw GO powder reveals very weak characteristic bands probably due to high scattering. The spectrum of CNT material mainly reveals the bands of CO, COH and C-C, whereas urea and melamine spectra show the contribution of typical bands of their N-containing groups.…”

This review acmes the latest developments of composites of metal oxides/sulfide comprising of graphene and its analogues as electrode materials in the construction of the next generation of supercapacitors (SCs). SCs have become an indispensable device of energy-storage modes. A prompt increase in the number of scientific accomplishments in this field, including publications, patents, and device fabrication, has evidenced the immense attention they have attracted from scientific communities. These efforts have resulted in rapid advancements in the field of SCs, focusing on the development of electrode materials with features of high performance, economic viability, and robustness. It has been demonstrated that carbon-based electrode materials mixed with metal oxides and sulfoxides can perform extremely well in terms of energy density, durability, and exceptional cyclic stability. Herein, the state-of-the-art technologies relevant to the fabrication, characterization, and property assessment of graphene-based SCs are discussed in detail, especially for the composite forms when mixing with metal sulfide, metal oxides, metal foams, and nanohybrids. Effective synthetic methodologies for the nanocomposite fabrications via intercalation, coating, wrapping, and covalent interactions will be reviewed. We will first introduce some fundamental aspects of SCs, and briefly highlight the impact of graphene-based nanostructures on the basic principle of SCs, and then the recent progress in graphene-based electrodes, electrolytes, and all-solid-state SCs will be covered. The important surface properties of the metal oxides/sulfides electrode materials (nickel oxide, nickel sulfide, molybdenum oxide, ruthenium oxides, stannous oxide, nickel-cobalt sulfide manganese oxides, multiferroic materials like BaMnF, core-shell materials, etc.) will be described in each section as per requirement. Finally, we will show that composites of graphene-based electrodes are promising for the construction of the next generation of high performance, robust SCs that hold the prospects for practical applications.
