“…While for the twofold device in series, its C d can achieve up to 616.9 F/g with the E d of 54.8 Wh/ kg and the same P d of 500 W/kg. These values show significantly higher than those of similar previously reported allsolid-state devices fabricated by PEDOT:PSS/reduced-graphene oxide, [78] 3D GCNW/PEDOT: PSS composite materials [79] and PEDOT:PSS/AgNFs network, [80] PPy coated MWCNT, [81] interconnected porous carbon derived from coal tar pitch and cellulose, [82] etc. Ragone plot of power density versus energy density of the PD2ET-g-SWCNTs device and the comparison with the other reported results were shown in Figure 10c.…”

Poly(3‐oligo(ethylene oxide))thiophene (PD2ET) with an ethanolamine terminal in the side chain was covalently grafted onto the surface of single‐walled carbon nanotube bundles (PD2ET‐g‐SWCNTs) by using an esterification reaction. The chemical bond between PD2ET and the SWCNTs is confirmed by using various techniques, such as Fourier transform infrared (FTIR), Raman spectroscopy, and X‐ray photoelectron spectroscopy (XPS) analysis. The microstructural and morphological investigation revealed a good distribution of PD2ET on the surface of the SWCNTs, with a thickness of about 2–3 nm. As an electroactive material, the fabricated PD2ET‐g‐SWCNTs electrode demonstrated high capacitive performance in electrochemical tests, in which an efficient specific capacitance of 399 F/g at 1 A/g was obtained from galvanostatic charge/discharge techniques. Furthermore, the long‐term stability investigation of PD2ET‐g‐SWCNTs electrode showed that over 91 % capacitance retention could be retained after 8000 successive charge/discharge cycles. The integrated two‐electrode supercapacitor based on the PD2ET‐g‐SWCNTs hybrid exhibited a high energy density of 22.5 Wh/kg and a power density of 500 W/kg at 0.625 A/g. The enhanced electrochemical behavior of the PD2ET‐g‐SWCNTs hybrid can be ascribed to the contribution of oligo(ethylene oxide), which facilitates ion diffusion and enables a faster charge process, thus rendering high efficiency in supercapacitors.

“…Many of them exhibit good mechanical stability, flexibility, and even stretchability. [25,31,[95][96][97] Generally, as shown in Figure 3a, the FoM c of metallic grids-based TESEs is high, ranging from 0.5 to 167 F S cm À 2 . Moreover, the energy density of devices based on metallic grids-based TESEs can be high due to the high areal capacitance of the electrode.…”

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.

Supercapacitors have received considerable attention as energy storage devices owing to their high power density, fast charge/discharge rate, and long cyclic life. Especially with an increasing demand for flexible and wearable devices, research on flexible supercapacitors has surged in recent years. The silver nanowire (Ag NW) network has been used as a flexible electrode owing to its excellent mechanical and electrical properties; however, its use as an electrode for flexible supercapacitors has been limited due to insufficient electrochemical stability. In this study, we proposed a method to resolve this issue. We employed a solution process that enabled the coating of the surface of Ag NW by a thin Au shell of ≈ 5 nm thickness, which significantly improved the electrochemical stability of the Ag NW network electrodes. Furthermore, we confirmed for the first time that MnO2, which is one of the most widely used capacitive materials, can be directly electroplated on the AACS NW network electrode. Finally, we fabricated a high-performance and flexible solid-state supercapacitor using the suggested Ag/Au/MnO2 core–shell NW network electrodes.
