“…In high-resolution Ni 2p spectra, as shown in Fig. 3d, two main peaks at about 855.7 and 873.4 eV are assigned to Ni 2p 3/2 and Ni 2p 1/2 spin orbits, respectively [50,51]; as well, two distinct peaks centered at around 861.6 and 880.1 eV are shake-up satellites of Ni 2p 3/2 and Ni 2p 1/2 , respectively, which are in accordance with that of previous reports, demonstrating that the existence form of nickel ions in the Ni-MOF/C-CNTs nanosheets is divalent state [43,48]. Regarding the O 1 s spectrum, as revealed in Fig.…”

HIGHLIGHTS • The ultrathin nickel metal-organic framework (MOF) nanosheets in situ interpenetrated by functional carboxylated carbon nanotubes (C-CNTs) were successfully constructed. The incorporated C-CNTs effectively adjust the layer thickness of Ni-MOF nanosheets. • The integrated hybrid MOF nanosheets delivered the boosted electrochemical performances and exhibited superior specific capacity of 680 C g −1 at 1 A g −1 .

development, but these energy sources have geographical limitations and instability, so it is difficult to achieve a wide range of applications. As an important part of sustainable energy development, electrochemical energy storage has become an area of active research in recent decades. [7-10] In the current energy market, lithium ion batteries (LIBs) are dominant in the automobile, medical equipment, and portable wearable device industries, among others, which can be attributed to their outstanding energy density and environmental protection performance. [11,12] However, the use of organic solvent-based electrolytes may raise safety issues and increase costs. [13-19] Therefore, the creation of an efficient battery system is very important. Compared with nonaqueous batteries, aqueous rechargeable batteries have the characteristics of low cost, nontoxicity, and incombustibility, and are more economically competitive than lithium technology in terms of largescale deployment. [20-22] Therefore, the most important task at present is to develop an ideal battery device with low cost, acceptable safety, long cycle performance, and environmental friendliness as a substitute for LIBs. [23-25] For the past few years, ion batteries with polyvalent metals as the negative electrodes have attracted much attention. Polyvalent cations (Zn 2+ , Mg 2+ , Al 3+) transfer twice or even three times as many electrons into the main material as monovalent cations (Li + , Na +), and each polyvalent positive ion can be inserted into the main compound. [26-32] Theoretically, the capacity of the host material depends on the number of transferred electrons coexisting with the intercalated ions, such that multivalent positive ions have higher weight capacity and energy density. [33] Notably, the element zinc (Zn) has become a common choice for a negative electrode material, owing to its ample sources, low price, low redox potential (−0.76 V vs standard hydrogen electrode), and high surface capacity. [34,35] The mixture of aqueous solution and/or aqueous solution and organic-based electrolyte has emerged as a new research field. Therefore, aqueous zinc ion batteries (ZIBs) have been widely considered for their advantages of high safety, low price, ecological friendliness, and high theoretical capacity. [36] Typically, aqueous ZIBs consist of a Zn metal negative electrode, an aqueous electrolyte that accounts for a majority of the battery material, and a positive electrode containing Zn 2+ ions. [37] A survey has revealed that the conventional With the increasing dependence on high power equipment, there is an urgent need to develop advanced and sustainable energy systems. As one of the main energy storage devices, battery research should make great efforts to implement the sustainable development strategies on ecological, clean and environmentally friendly energy. Currently, aqueous zinc ion batteries (ZIBs) have gained much attention owing to their cheapness, abundant resources, high safety, and ecological friendliness. Nevertheless, ZIBs als...

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.
