“…The booming market of smart wearable and integrated electronics, such as electronic skins, smart textiles, flexible displays, and personal health monitoring, has stimulated the demand for flexible energy storage devices. − SCs, as one of the commercial power sources, play an increasing significant role in wearable and integrated devices due to their exceptional power density and high cycle efficiency up to a million cycles. − It is well known that Faraday pseudocapacitors can provide much higher energy density than electric double-layer capacitors (EDLCs) due to different energy storage mechanisms. − In the past decades, lots of transition metal compounds have been widely exploited as pseudocapacitor materials to achieve high capacitive performance. However, poor electrical conductivity and low rate performance limit the full play of their theoretical capacitance .…”

The rapidly developing wearable flexible electronics makes the development of high-performance flexible energy storage devices, such as all-solid-state supercapacitors (SCs), particularly important. Herein, we report the fabrication of CNTs/NiCoSe 2 hybrid films on carbon cloth (CC) through a facile co-electrodeposition method based on flexible electrodes for all-solid-state SCs. The NiCoSe 2 sheets grown on CNTs uniformly with a diameter of 50−100 nm act as the active materials. The CNTs in the hybrid films act as the scaffold to offer more deposition sites for NiCoSe 2 and provide a conductive network to facilitate the transfer of electrons. Moreover, the one-step electrodeposition process avoids the usage of any organic binders. Benefiting from the high intrinsic reactivity and unique 3D architecture, the obtained CNTs/NiCoSe 2 electrode delivers high specific capacity (218.1 mA h g −1 ) and satisfactory durability (over 5000 cycles). Remarkably, the CNTs/NiCoSe 2 //AC flexible all-solid-state (FASS) ASC provides remarkable energy density (112.2 W h kg −1 ) within 0−1.7 V and maintains 98.1% of its initial capacity after 10,000 cycles. In addition, this flexible ASC device could be fabricated at a large scale (5 × 6 cm 2 ), and the LED arrays (>3.7 V) can be easily lighted up by three ASCs in series, showing its potential practical application.

“…However, most MOFs have low electrical conductivity, limiting their use in SCs. To solve this difficulty, Kale et al [131] developed a simple approach to generate nanoflowers like NiÀ MOFs using acid treatment to boost electrical conductivity without breaking their framework. The prepared NiÀ MOFs exhibited excellent surface morphology and demonstrated outstanding EES properties.…”

Metal‐Organic Frameworks (MOFs), a novel class of porous extended crystalline structures, are favored in different fields of heterogeneous catalysis, CO2 separation and conversion, and energy storage (supercapacitors) due to their convenience of synthesis, structural tailor‐ability, tunable pore size, high porosity, large specific surface area, devisable structures, and adjustable compositions. Nickel (Ni) is a ubiquitous element extensively applied in various fields of catalysis and energy storage due to its low cost, high abundance, thermal and chemical stability, and environmentally benign nature. Ni‐based MOFs and their derivatives provide us with the opportunity to modify different properties of the Ni center to improve their potential as heterogeneous catalysts or energy storage materials. The recent achievements of Ni−MOFs and their derivatives as catalysts, membrane materials for CO2 separation and conversion, electrode materials and their respective performance have been discussed in this review.

The electrochemical performance of the Faradaic battery-type binary metal oxide electrodes is dependent on the desirable architecture and the optimal cationic ratio. Herein, we report one-dimensional nanowire-like bimetallic spinel Ni x Co 3-x O 4 (NCO) electrode materials for high performance hybrid supercapacitor (HSC) applications. This unique nanowire architecture is beneficial for providing abundant exposed active sites onto the large accessible surface area, which results in facilitating ion transporting pathways. Remarkably, the optimal NCO electrode with the ratio of Ni/Co of 1 to 1 (NCO11) achieves the maximum specific capacitance of 1033 F g À1 at 1 A g À1 and the excellent rate capability of 74.55% at 30 A g À1 , far exceeding those of their single counterparts. Furthermore, the as-assembled HSCs integrating NCO11 and AC electrodes deliver large energy and power densities of 41.54 W h kg À1 and 44.95 kW kg À1 with excellent cyclic retention (96.12%).
