“…Transition metal hydroxide is a representative class of pseudocapacitive materials for supercapacitors. [ 130 ] Three transition metal hydroxides, including Ni(OH) 2 , [ 23a,131 ] Co(OH) 2 , [ 67 ] and FeOOH, [ 132 ] have been explored to prepare FTCEs for FTSCs. Ni(OH) 2 and Co(OH) 2 contribute a theoretical C g of 2082 [ 133 ] and 3560 F g −1 , [ 134 ] respectively, due to the reversible redox reaction and large interlayer structure.…”

“…prepared Ag/Ni(OH) 2 FTCEs through simply coating Ni(OH) 2 nanosheets on Ag NWs film ( Figure a–c), in which the dense junction contacts between NWs and Ni(OH) 2 reduced R s , improved stability and electron transport of Ni(OH) 2 , and thus enhancing the pseudocapacitive performance. [ 131 ] In addition, Ag NWs/Ni(OH) 2 FTCEs had a low R s of 18.56 Ω sq −1 and high T 550 nm of 90.26%. The corresponding Ag/Ni(OH) 2 FTSCs displayed a high C g of 78 F g −1 at 0.5 A g −1 , long‐term stability of 62.5% after 1000 cycles and 54% of initial capacitance after 300 bending times under the bending angle of 180°, indicating a potential application in portable electronics.…”

The progressive development of flexible transparent portable electronic devices is in urgent need of matching power sources. Flexible transparent supercapacitors (FTSCs) are the core resources due to their high optical transmittance, endurable mechanical flexibility, excellent electrochemical performance, and facilely accessible device configuration. This review organizes the rational design of nanostructured electrode materials toward FTSCs. First, the structure, mechanism, and property of FTSCs are introduced. Then, the design principles of diverse electrode materials are discussed to achieve flexible transparent conductive electrodes (FTCEs) with different figure of merits (both electrical FoMe and capacitive FoMc), mechanical strength, and environmental stability. Following the achievements in multifunctional FTSCs focusing on film‐supercapacitors, micro‐supercapacitors, electrochromic supercapacitors, photo‐supercapacitors, and battery‐like supercapacitors are also highlighted. Finally, the current challenges and future perspectives on viable materials in the construction of FTSCs to power portable electronics are outlined.

“…Considering the high aspect ratio of nanowires, metallic grids are believed to be more desirable for portable and flexible electronics. To date, various metallic grids have been developed and applied in TESEs, including Ag, [24,27,[77][78][79][80][81][82][83][84][85][86][87] Au, [16,[88][89][90][91] Ni, [92][93][94] and so on. Many of them exhibit good mechanical stability, flexibility, and even stretchability.…”

Transparent energy-storage devices have aroused interest because of the ever-increasing demands of transparent electronics. Transparent energy-storage electrodes (TESEs) are indispensable for emerging cutting-edge products and have thus attracted remarkable attention in the past decade. This minireview begins by introducing the basic evaluation metrics for TESEs. Then, recent progress of various types of TESEs such as carbonaceous materials, polymers, MXenes, and other conductive substrates-based TESEs is outlined. In order to provide some inspiration and guidelines, we focus on summarizing the presently proposed strategies towards high-performance TESEs together with the applications of transparent supercapacitors. At the end of this minireview, we discuss the outlook and perspectives towards the development of transparent energy-storage devices.

“…The initial Ag nanostructures could be obtained by various methods, such as electrodeposition and hydrothermal method [15]. After that, the metal hydroxides/oxides were grown on the Ag electrode surface via hydrothermal or electrodeposition [16,17]. The hierarchical structure is helpful to exert the synergistic effect between each component and enhances the overall electrochemical properties thereby.…”

Hierarchical Ag@Ni(OH)2 nanospheres were achieved directly on copper foam substrate through a convenient two-step process. Ag nanoflowers were formed on copper substrate by galvanic replacement technology between AgNO3 and copper foam followed by electrodeposition of a layer of Ni(OH)2. Ag nanostructures as cores not only dominated the final morphology of the composites, but also improved the electrical conductivity, increased the specific surface area of the active electrode material, and even directly participated in the electrochemical reactions. The resulted Ag@Ni(OH)2 nanospheres could be directly used as high-performance binder-free electrodes and exhibited enhanced electrochemical performance with a high specific capacitance of 1.864 F cm−2 and long cycling lifespans of 90.43% capacity retaining after 3000 cycles.
