“…Such argumentation is well attested by its capability of simultaneously lighting up an array of indicators containing 9 LED lamps arranged in a "LCC" pattern via series connection with eight additional entities (Figure 5f). [62][63][64][65] Those outstanding device performances unambiguously punctuate its great promise as an energy-rich and highly stable power source (Figure 5e, f). Such argumentation is further reinforced in view of, on the one hand, its good flexibility, as evidently reflected in the absence of the capacitance loss even if the Bi 2 O 2 CO 3 /CC//CoNi-LDHs/Cu NWs/CC pseudocapacitor is strongly distorted (Figure 5g).…”

A combination of high mass loading and efficient utilization of electroactive materials is crucial for simultaneously enhancing the energy and power densities of energy storage devices. This is exemplified herein using cobalt nickel layered double hydroxides nanosheets (CoNi‐LDHs) directly grown on copper nanowires (Cu NWs) standing quasi‐vertically on carbon cloth (CC) to yield a multi‐core‐shell CoNi‐LDHs/Cu NWs/CC as the supercapacitor electrode that exhibits a high areal capacitance of 5.55 F cm−2 (corresponding to a gravimetric capacitance of 1209.15 F g−1) at a large current density of 10 mA cm−2. Such superior rate capability is attributed to the high packing density of CoNi‐LDHs in the electrode, benefitting from the large specific surface area of Cu NWs/CC. Additional contribution stems, on the other hand, from the facile charge transfer kinetics resulted from the elimination of binder from the electrode coupled with the mesopores between not only Cu NWs but also CoNi‐LDHs nanosheets, and the macropores between the carbon fiber of CC. Benefitting from such exceptional rate performance is the supercapacitor built on CoNi‐LDHs/Cu NWs/CC as the positive electrode coupled with bismuth subcarbonate (Bi2O2CO3) as the negative electrode capable of delivering outstanding power density of 13.31 mW cm−2 and energy density of 0.35 mWh cm−2.

One of the most exciting new developments in energy storage technology is flexible Zn-ion hybrid supercapacitors (f-ZIHSCs), which combine the high energy of Zn-ion batteries with high-power supercapacitors to satisfy the needs of portable flexible electronics. However, the development of f-ZHSCs is still in its infancy, and there are numerous barriers to overcome before they can be widely implemented for practical applications. This review gives an up-to-date description of recent achievements and underlying concepts in energy storage mechanisms of f-ZIHSCs and emphasizes the critical role of cathode, anode, and electrolyte materials systems in speeding the prosperity of f-ZIHSCs. The innovative nanostructured-based cathode materials for f-ZIHSCs include carbon (e.g., porous carbon, heteroatom-doped carbon, biomass-derived porous carbon, graphene, etc.), metal-oxides, MXenes, and metal/covalentorganic frameworks, and other materials (e.g., activated carbon, phosphorene, etc.) are mainly focused. Afterward, the latest developments in flexible anode and electrolyte frameworks and impacts of electrolyte compositions on the electrochemical properties of f-ZIHSC are elaborated. Subsequently, the advancements based on fabrication designs, including quasi-solid-state, micro, fiber-shaped, and all climate-changed f-ZIHSCs, are discussed in detail. Lastly, a summary of current challenges and recommendations for the future progress of advanced f-ZIHSC are addressed. This review article is anticipated to further understand the viable strategies and achievable approaches for assembling high-performance f-ZIHSCs and boost the technical revolutions on cathode, anode, and electrolytes for f-ZIHSC devices.

“…Preparing composite electrodes via surface modification or doping treatment of CNTs with various pseudocapacitance materials has been confirmed as an effective approach to obtain a capacitor with better overall performance. The pseudocapacitance materials such as metal oxides, [22][23][24][25][26] metal sulfides, [27][28][29][30] and conductive polymers, [31][32][33][34][35] have been used for compounding or doping with CNTs to significantly improve the electrochemical performance of the capacitors. Pseudocapacitors store energy through the reversible faradaic reaction of the electrodes.…”

The continuously reinforced carbon nanotube woven film (CNWF) prepared via the floating catalytic chemical vapor deposition (FCCVD) was modified by mixed acid and vinyltrimethoxysilane (VTMS) respectively to obtain carbon nanotube woven film (CNWF@VTMS) grafted with CH 2 CH group. A series of novel self-supporting composite electrode materials (CNWF@VTMS/PANI) for supercapacitors were then prepared by in-situ chemical oxidative polymerization of aniline in the presence of the CNWF@VTMS film substrate as a conductive network framework. The results showed that CNWF@VTMS/PANI 14 flexible electrode with grape-clustered structure exhibited the highest specific capacitance of 531.3 F/g and the highest energy density of 26.5 Wh/kg at the current density of 1 A/g. It could maintain 75.1% of the initial value at a high current density of 10 A/g. The excellent electrochemical cycle and the structural stability have been confirmed on the condition of the higher capacitance retention of 96.6% after 2000 times of galvanostatic charge/discharge, and the almost unchanged electrochemical performances after 300 times of bending and twisting. Meanwhile, the stronger interfacial bonding between CNWF and PANI endowed a higher tensile strength of 129.2 MPa.
