Sodium‐ion batteries (SIBs) are gaining renewed interest as a promising alternative to the already commercialized lithium‐ion batteries. The large abundance, low cost, and similar electrochemistry of sodium (compared with lithium) is attracting the attention of the research community for their deployment in energy storage devices. Despite the fact that there are adequate cathode materials, the choice of suitable anodes for SIBs is limited. Graphite, the most versatile anode for LIBs, exhibits poor performance in case of SIBs. Amorphous or disordered carbons (hard and soft carbon) have been the most promising and cost‐effective anode materials for SIBs. This Review discusses the recent advances of various forms of amorphous or disordered carbons used in SIBs with emphasis on their synthesis processes and relationship between microstructure, morphology, and performance. A profound understanding of the charge storage mechanisms of sodium in these carbon materials has been deliberated. The performance of these anode materials also depends upon electrolyte optimization, which has been aptly conferred. However, these anodes are often plagued with large voltage loss, low initial coulombic efficiency, and formation of solid electrolyte interphase. In order to overcome these challenges, several mitigation strategies have been put forward in a concise way to offer visions for the deployment of these amorphous carbon materials for the progress and commercial success of SIBs.

“…Owing to the larger radii of the Na + /K + ion (Na: 1.02 Å, K: 1.38 Å vs. Li: 0.76 Å), as well as their very distinct differences in radii, it is very difficult to identify a single electrode material that is simultaneously suitable for both SIBs and PIBs. For example, graphite based on (de)intercalation mechanism is an attractive anode material in PIBs, [3] but it exhibits very limited capacity in SIBs [4] . On the other hand, a metal bismuth anode, based on a (de)alloying mechanism, can deliver a specific capacity of 385 mAh g −1 for SIBs and PIBs [5]…”

Molecule‐aggregation organic electrodes in principle have the capability for “single‐molecule‐energy‐storage” in metal‐ion rechargeable batteries, which indicates that the same organic electrode can be simultaneously applied to multiple metal‐ion rechargeable batteries. In this study, the polyanionic organic compound 9,10‐anthraquinone‐2,6‐disulfonate (Na2AQ26DS, 130 mAh g−1) is used as a common cathode and metal bismuth (Bi) as a common anode to simultaneously assemble low‐cost Na‐ion and K‐ion full cells. The Na‐ion full cells can deliver the peak discharge capacity of 139 mAh g−1cathode at 0.5–3.0 V, and the K‐ion full cells can show the peak discharge capacity of 130 mAh g−1cathode at 0.5–3.0 V. These results are comparable to the best organic‐based Na‐ion and K‐ion full cells reported to date.

“…Most recent application of graphene and its derivatives such as GO, is in polymer nanocomposites, where GO can be grafted with a variety of polymeric chains to significantly improve the targeted properties [5]. Hence, several interesting studies [6][7][8] have shown that GO significantly improves the properties of polymer based composites, where the synthesized GO polymer nanocomposites have demonstrated a high potential for use in a variety of applications, particularly high performance energy materials, electrocatalysts, drug delivery carriers, biosensors, and biomedical materials [9][10][11]. Nevertheless, the dispersion behavior of GO in polymer is very important towards the quality of the composites as this may impedes its broader application, hence, several preparation methods has been employed to synthesize GO in polymer from the perspectives of application and proficiency, some of these methods includes Solution mixing, Electropolymerization, Melt compounding etc All these methods and others have been employed for the fabrication of GO-polymer nanocomposites.…”

The negligence of used waste polymers often results in the waste of resources and constitutes serious environmental pollutants. Therefore, it becomes necessary to practically provide a means of converting these waste polymers to useful resources. For this purpose, the potential applicability of some selected waste polymers as the active photosensitizer material in dye-sensitized solar cells were exploited using density functional theory. In this research work, density function theory (DFT) is applied to investigate the interaction of graphene oxide (GO) with monomers of Polypyrrole (PPy), Poly (phenylene vinylene) (PPV), Poly(vinyl alcohol) (PVA), and Polyvinyl Pyrrolidone (PVP) polymers. The geometrical structures of the hybridized nanocomposites GO-PPy, GO-PPV, GO-PVA, and GO-PVP are fully optimized at wB97XD/6–311++G(d,p) computational method. All of the nanocomposites’ optoelectronic properties, the excitation type and the wavelengths, oscillator strengths, as well as the dominant transitions were calculated. Atoms-in-molecules (AIM) and natural bond orbital (NBO) analysis were used to analyze the strength and nature of the composites. The results of the ground state energy gap revealed that the hybridized nanocomposites are semiconducting in nature while the 3.7020 eV energy gap of the GO-PVA makes it the most stable among the various nanocomposites. The thermodynamic calculation of the various nanocomposites shows that the GO-PVA nanocomposite is highly endothermic among the various nanocomposites with free energy value of 353.71kcal mol−1. The results of the density of state (DOS) analysis show that the p-orbitals in all of the different nanocomposites had the highest density contribution to the frontier molecular orbitals, and are also found to dominate the anti-bonding states densities.
