“…Metal–organic frameworks (MOFs) and their composites have been considered as active masses in supercapacitor electrodes [ 239 , 240 , 241 , 242 ]; combined with ICPs, the obtained composites were examined for various electrochemical applications [ 243 ]. The poor electronic conductivity of MOFs was noticed as a major hindrance to their use in a supercapacitor electrode; forming composites [ 156 , 244 , 245 , 246 ], including ICPs, is an obvious solution [ 77 , 242 ].…”

Intrinsically conducting polymers ICPs can be combined with further electrochemically active materials into composites for use as active masses in supercapacitor electrodes. Typical examples are inspected with particular attention to the various roles played by the constituents of the composites and to conceivable synergistic effects. Stability of composite electrode materials, as an essential property for practical application, is addressed, taking into account the observed causes and effects of materials degradation.

“…Transparent energy storage devices have been drawing much attention in recent years due to the emergence of smart windows and the rapid development of solar cells and touchscreen electronics. − Among all energy storage devices, supercapacitors show much promise due to their fast charging ability and cycling stability. Supercapacitors also bridge the gap between electrolytic capacitors and batteries in terms of energy and power densities. − Various factors are evaluated for a transparent supercapacitor, including transparency, energy and power densities, specific capacitance, and cycle stability. − ,, Among the materials for energy storage, poly(3,4-ethylenedioxythiophene) (PEDOT) rises as one of the most promising supercapacitor electrode materials due to high conductivity, environmental stability, light weight, and ease of synthesis. , A major challenge for depositing this conducting polymer on a glass substrate is the lack of molecular interactions between organic and inorganic moieties resulting in poor adhesion and low cycle stability of the electrode. ,, Many studies overcome this challenge by embedding polymers in a framework, utilizing a sacrificial layer, or creating polymer/metal oxide composites. ,− However, these studies rely on glass with conductive coatings, such as fluorine-doped tin oxide or indium-doped tin oxide, that are both susceptible to dissolution in an acidic environment and potentially costly for large-scale implementation. Inspired by silanization and Friedel–Crafts alkylation mechanisms, ,− we present an alternative approach by covalently linking a polymer and glass through a self-assembled diphenyldimethoxysilane monolayer.…”

Conducting polymers rise among some of the most promising transparent supercapacitor electrode materials due to high conductivity, environmental stability, light weight, and ease of synthesis. A major challenge for depositing conducting polymers on a glass substrate is the lack of molecular interactions between organic and inorganic moieties resulting in poor adhesion and low cycling stability of the electrode. We present a synthetic approach by covalently linking poly(3,4-ethylyenedioxythiophene) (PEDOT) and glass through Friedel–Crafts alkylation on a self-assembled diphenyldimethoxysilane monolayer. This method obviates the need for a conductive FTO or ITO coating, enabling the fabrication of current collector-free planar supercapacitor electrodes on any glass surface. The electrode produced from our vapor-phase synthesis is coated with a highly conductive nanofibrillar PEDOT film (sheet resistance 2.1 Ω/□) possessing a gravimetric capacitance of ∼200 F/g. Our PEDOT planar supercapacitor possesses outstanding stability (86% capacitance retention after 50,000 cycles). We also fabricate a proof-of-concept transparent tandem supercapacitor on PEDOT-coated glass using 3D-printed frames that supplies enough voltage and current to light up a blue light-emitting diode (LED).

“…[1][2] As a neotype of energy storage devices, supercapacitors are characterized by high power density, short charging and discharging time, high cycle life, environment-friendly and safety. [3] The classification of supercapacitors according to the energy storage mechanism is electric double layer capacitors (EDLCs), pseudocapacitors (PCs) and hybrid supercapacitors. [4] Among them, the electrode materials of EDLCs are mainly high specific area and porous carbon materials, and their cycle life can reach millions of times.…”

To meet the demands of modern vehicles and electronic devices, an increasing number of new materials for the cathode of high-performance supercapacitors have been studied in depth. Here, GO/NA-Cl composites were successfully fabricated by in-situ grow NiAl layered double hydroxide (NiAl LDH) nanosheets on graphene oxide (GO) flakes through one-step hydrothermal procedure for the cathode of supercapacitor. The image of scanning electron microscopy (SEM) exhibited that the NiAl-Cl LDH nanosheets were evenly and vertically arranged on the GO flakes and interlaced to form a network structure, presenting a considerable surface area, which afford abundant active sites in contact with the electrolyte and alleviate the expansion of GO/NA-Cl during the process of electrochemical reaction to improve its stability. The results of electrochemical test show that the GO/NA-Cl is a typical pseudocapacitive material, which provides a prominent specific capacity of 1573 F/g at 1 A/g, and superior rate property (the rate of capacity retention is 62% even at 20 A/g). Furthermore, the GO/NA-Cl electrode shows a superior cycling life after 1000 cycles at 1 A/g with about 80% capacitance retention.
