“…Thus incorporation of Au -particles acted as nano-fillers to improve the charge transport properties of the resultant composite. [263] Another instance in the recent past reports the fabrication of symmetric sandwiched RuO 2 /C/RuO 2 electrodes with concentric architecture using template-assisted synthesis that showed outstanding specific capacitance values especially at very high scan rates. The so-designed smart system contained mesoporous channels for rapid electrolyte passages, and promoted efficient utilization of active material even with low Ru loading making the device highly potential for practical energy storage applications.…”

Electrochemical energy storage has emerged as one of the principal topics of present‐day research to deal with the high energy demands of modern society. Accordingly, besides fuel cells and battery technologies, interesting and challenging results have been observed in the recent past, during the materialization of “supercapacitors” or “ultracapacitors”, which have provoked a sharp increase in research inclination to revisit this aspect of renewable and sustainable energy storage. Supercapacitor performances are largely dependent on electrode materials, the nature of the electrolyte used, and the range of voltage windows employed. Carbon‐based electrode materials have tunable properties such as electrical conductivity, extensive surface area, and faster electron transfer kinetics with low fabrication costs. But their specific capacitances are found to be too low for commercialization. Ruthenium dioxide (RuO2), owing to its high theoretical specific capacitance value (1400–2000 F g−1), has been extensively recognized as a favorable material for supercapacitor devices, but high production cost and agglomeration effects stand as high barriers preventing marketable usage. Consequently, RuO2‐based nanocomposites have been widely studied to optimize the material cost, with simultaneous improvement in the electrochemical performances. This Review describes comprehensively the recent progress in terms of the fabrication and design, electrochemical performance, and achievements of RuO2 and its nanocomposites as electrode materials for supercapacitors, which will be beneficial for further research designing high‐performance supercapacitor devices.

“…Pentazolate anion ( cyclo -N 5 – ) is receiving ever-increasing significant interest because of its potential application in high-energy density materials. 1 − 9 Especially, since 2016, several breakthroughs have been witnessed in this field, including some metal-free pentazolate hydrates [such as (N 5 ) 6 (H 3 O) 3 (NH 4 ) 4 Cl salt] and metal salts {such as [Na(H 2 O)(N 5 ) 2 ]·2H 2 O, [Mn(H 2 O) 4 (N 5 ) 2 ]·4H 2 O and [Mg(H 2 O) 6 (N 5 ) 2 ]·4H 2 O} synthesized in experimentation under ambient conditions. 10 − 21 However, the nonenergetic group (such as water and halogen) lowers the nitrogen concentration as well as energy density of these compounds.…”

Recently, it has been reported that high-pressure synthesized lithium pentazolates could be quenched down to ambient conditions. However, the crystalline structures of LiN 5 under ambient conditions are still ambiguous. In this work, the structures of LiN 5 compound were directly explored at atmospheric pressure by using a new constrain structure search method. By using this method, three new allotropes were confirmed, and they show lower energy than the previous reported LiN 5 phases. Both their thermodynamic and dynamic stability were confirmed through formation enthalpies, phonon spectrum, and ab initio molecular dynamics simulations under ambient conditions. Moreover, these three allotropes show similar formation enthalpies and properties, which suggests that it is hard to obtain a single LiN 5 phase, which is well consistent with the experimental phenomenon. Furthermore, because of their low formation energy, all of them possess low energy density when they directly decompose to Li 3 N and nitrogen (0.52 kJ/g). Instead, the decomposed energy could be further improved to 3.78 kJ/g when they decompose under an oxygen-rich environment.

“…Similar observation using ammonium-based ionic liquid is reported elsewhere. [32,33] Similarly, the cyclic voltammogram of SnCl 2 dissolved in [HmPip] [OTf] recorded from open circuit potential to negative voltage and cycled back again to the same point (red curve of figure 1). The redox behavior of Sn 2 + present in the solution of SnCl 2 present in [HmPip][OTf] phase showed an onset of reduction wave at À 0.75 V (Vs. Pt) that engenders a peak at the cathodic potential (Ep c ) of À 1.26 V (Vs. Pt) referring the formation of Sn 2 + / Sn couple.…”

New protic ionic liquid, namely 1‐Methylpiperidinium trifluoromethane sulphonate [HmPip][OTf] was synthesized and employed for the dissolution of Cu and Sn metal precursors followed by the electrodeposition process of the subsequent metals. The cyclic voltammogram of [HmPip][OTf], CuCl2 (80 mM) in [HmPip][OTf] and SnCl2 (65 mM) in [HmPip][OTf] phase recorded at glassy carbon electrode (working electrode), with the glassy carbon as counter and platinum as the reference electrode. The CV indicates that Cu2+ underwent two‐step one‐electron transfer, whereas Sn2+ reduced via one step two‐electron transfer. The diffusion coefficient of Cu1+, Cu2+ and Sn2+ ions in [HmPip][OTf] phase were evaluated by the CV method. The experimental temperature and the scan rate were set at 353 K and 110 mV/s respectively. Electrodeposition of Cu and Sn was done at their corresponding reduction potential determined from cyclic voltammetry. Spectroscopic investigation of the deposits obtained after electrodeposition is done by SEM‐EDX as well as XRD.
