“…Unfortunately, the low ionic conductivity, high environmental toxicity and expensive nature of these organic electrolytes seriously hinder their practical applications in high-performance flexible SCs. Alternatively, constructing asymmetric supercapacitors (ASCs) with aqueous gel polymer electrolytes are recently emerging as an available strategy to gain the energy density of flexible SCs by increasing the cell potential from 1 to 2 V [15,[17][18][19][20][21][22][23]. Moreover, in comparison to organic electrolytes, aqueous gel polymer electrolytes have higher ionic conductivity and much less toxicity, which could offer high power density and great promise for wearable devices [6].…”

Metal Oxynitrides as Promising Electrode Materials for Supercapacitor Applications

In the past decade, due to the demands of the electrochemical energy storage sector, there has been a quest for novel supercapacitor materials that offer champion storage characteristics. Metal oxynitrides are seen as potential candidates for electrochemical energy storage owing to their high cyclability (up to 10 5 cycles), good intrinsic conductivity (30000-35000 S cm À 1 ), good wettability, corrosion resistance, and chemical inertness. In this review, the use of metal oxynitrides as electrode materials for supercapacitors is discussed. A comparison of oxynitrides with other electrode materials, such as metal oxides, carbon-based materials, and their composites, is made. This study also places emphasis on the impact of synthesis techniques on the final properties of the material. In view of this critical analysis, we envisage future directions for this category of energy storage materials.[a] U.

[ 22 ] For instance, although millions of miles of electrical cables have been used for providing electrical connections, the electrical energy produced from various physical or chemical sources to be distributed to users still need additional energy storage equipment, which causes unnecessary trouble and high cost. Moreover, people are possibly confronted with the inconvenience of sudden loss of power when using indoor electric appliances, and bothered by carrying heavy portable electronic accessories such as batteries and power cords simultaneously during a trip. Integrating the energy storage devices into appropriate energy transmission circuits should be an effective strategy to solve the problem of tiring energy distribution, sudden power off, and further lighten the weight of portable electronics, but current research barely involves the integration of energy storage devices and energy transit system, and these two systems still work independently with each other. [ 37,38 ] Supercapacitor, a promising class of energy storage device, is appealing because of its high power density, long cycle life time, and high energy effi ciency. [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] More importantly, supercapacitor can be easily fabricated in various confi gurations for ease of compatibility and integration with diversifi ed architectures of electronic devices. [55][56][57][58][59][60][61][62][63][64] From this, it can be expected that the integration of appropriate supercapacitor confi guration into proper circuit could achieve synchronous energy storage and energy transmission. Besides the confi guration, the exploration of naturally abundant and renewable biomaterials with high energy density for the new-generation green supercapacitors is intensively desired. [65][66][67][68][69] Thus, considering the issues of both the materials and confi guration, constructing an ideal integrated supercapacitor system based on renewable biomaterials for synchronous energy storage and transmission should be of scientifi c and technological importance due to their additional desirable economic, biocompatible and environmental friendly merits.Herein, we report the development of biocomposite-based fl exible integrated electrical cable for synchronous energy transmission and storage. In this unique integrated confi guration, the fi ber electrodes were alternately winded along the twisted electric wires, which worked not only as scaffolding to support and strengthen the slight electrodes but also as separators to spatially confi ne them to avoid short circuit ( Scheme 1 ). Distinct from the conventional electric wires used in a serial It becomes increasingly important to develop integrated systems with the aim of achieving maximum functionality for the state-of-the-art electronic devices. Here, a fl exible integrated electrical cable is reported by incorporating biomaterials based fi ber supercapacitors into a resistor-capacitor circuit. In this unique integrated confi gura...
