“…AC exhibits a high surface area (≈2000 m 2 g −1 ), superior conductivity (≈60 S m −1 ) and good structure stability, which are all favorable to its surface adsorption of ions. [ 62 ] AC is usually derived from carbonaceous materials such as charcoal, coal, coke, and biomass carbon. The final microstructure depends strongly on the precursors and synthesis conditions.…”

Various carbon nanomaterials are being widely studied for applications in supercapacitors and Li‐ion batteries as well as hybrid energy storage devices. Dual‐carbon batteries (DCBs), in which both electrodes are composed of functionalized carbon materials, are capable of delivering high energy/power and stable cycles when they are rationally designed. This Review focuses on the electrochemical reaction mechanisms and energy storage properties of various carbon electrode materials in DCBs, including graphite, graphene, hard and soft carbon, activated carbon, and their derivatives. The interfacial chemistry between carbon electrodes and electrolyte is also discussed. The perspective for further development of DCBs is presented at the end.

“…[142] Other anode materials tested in NICs include TiO 2 and sodium titanates, metal oxides, alloys, and organic materials, and the results have been summarized in various extensive review works. [143][144][145][146][147][148] NIC marketability would also benefit from the custom design of electrolytes. Most of the electrolytes used in NICs are just like the ones used in NIBs, even though the operation conditions of hybrid systems are different from battery requirements.…”

are proving to be an emergent technology with potentially very attractive properties. They are potentially low cost and environmentally friendly with reduced supply risk. However, the development of NIBs faces various challenges such as low gravimetric and volumetric energy densities and difficulty in achieving broader voltage windows. Although early studies in NIBs date back to the 1970s, just like Li-ion battery (LIB) research, the commercialization of the former systems in 1991 by the team formed by Sony and Asahi Kasei marked a milestone not only in the field of energy storage technology but also in the evolution of the modern society. This technological breakthrough had been possible thanks to several preceding contributions, particularly the works by M. S Whittingham, [1] J. Goodenough, [2,3] and A. Yoshino [4] on the discovery of Li-ion intercalation materials (Nobel Laureates in Chemistry 2019). This important historical event polarized material science research toward Li-ion technology and slowed down considerably the advances in the field of sodium. However, at the end of the 2000s, mainly driven by the concerns about future lithium supply and the uneven worldwide distribution of its reserves and resources, the research on Na-ion reemerged and so did the number of articles published (Figure 1). The intercalation chemistry of both metal ions is very alike, and thus, the materials tested for NIBs could be similar to those used in Li-ion systems. Both systems share the same working principle, and therefore, in terms of manufacturing, the industry producing LIBs can be easily tuned towards NIB fabrication, which is an important asset to invest in and support this technology. NIBs started to reach the market in the early 2010s, about two decades after their Li counterparts. Nevertheless, the progress has been relatively fast due to the straightforward LIB equipment and facility transfer just mentioned. In the search of high performance, low cost, abundance, low environmental impact, long-term cyclability and safety, layered metal oxides, polyanionic compounds and Prussian blue analogues (PBAs) are among the most studied families of Na-ion cathode materials. On the anode side, metallic sodium exhibits the same operation and safety problems as lithium, and therefore, it cannot be considered an option in conventional NIBs. Thus, in this scenario, most of the research has been dominated by the use of disordered carbons, mainly hard carbons (HCs). Other prospective anodes

“…When the electric field is scattered, the mutual attraction between the charges helps to form a stable electric double-layer, and the energy is stored in this process. During the discharging process, electrons flow from the negative to the positive electrode through the load, generating a current in the external circuit and the energy is correspondingly released [32][33][34] . Porous carbon materials are characteristic electrodes of EDLCs owing to their high specific surface areas that can contributing considerable EDL capacitance.…”

“…And during discharging, the ions will be released from the electrode surface, and the stored energy will also be released through the external circuit. In general, as ions can enter into the electrodes and participate in the redox reactions, the capacitance of pseudo-supercapacitors is 10-100 times higher than double-layer capacitance, which only utilize the surface to storage charges 32,35 . Pseudo-supercapacitors normally employ metal compounds and conducting polymer as electrode materials, which can offer rich faradic reactions.…”

The rapid development of wearable, highly integrated, and flexible electronics has stimulated great demand for on-chip and miniaturized energy storage devices. By virtue of their high power density and long cycle life, micro-supercapacitors (MSCs), especially those with interdigital structures, have attracted considerable attention. In recent years, tremendous theoretical and experimental explorations have been carried out on the structures and electrode materials of MSCs, aiming to obtain better mechanical and electrochemical properties. The high-performance MSCs can be used in many fields, such as energy storage and medical assistant examination. Here, this review focuses on the recent progress of advanced MSCs in fabrication strategies, structural design, electrode materials design and function, and integrated applications, where typical examples are highlighted and analyzed. Furthermore, the current challenges and future development directions of advanced MSCs are also discussed.
