A breakthrough in technologies having "green" and sustainable energy storage conversion is urgent, and supercapacitors play a crucial role in this area of research. Owing to their unique porous structure, amorphous materials are considered one of the best active materials for high-performance supercapacitors due to their high specific capacity, excellent cycling stability, and fast charging rate. This Review summarizes the synthesis of amorphous materials (transition metal oxides, carbon-based materials, transition metal sulfides, phosphates, hydroxides, and their complexes) to highlight their electrochemical performance in supercapacitors.

An IR electrochromic film constructed by copolymer of aniline and o‐nitroaniline has been successfully prepared by cyclic voltammetry. The effects of polymerization of aniline and o‐nitroaniline on electrochromic properties and optical properties were investigated by cyclic voltammetry, scanning electron microscopy, FTIR spectrometer, and UV–vis spectrophotometer. The results indicate that the film can exhibit three colors (apple green, dark green, and dark blue) at different voltages of −0.1, 0, and 0.8 V. Simultaneously, a fast response time (1.89 and 4.47 s), a high coloration efficiency, a significant optical modulation (60% between −0.1 and 0.8 V) and a large average emissivity range (Δεmax = 0.203) are achieved for the new film. © 2018 Wiley Periodicals, Inc.

material has a significant influence on the reaction kinetics, which subsequently alters the morphology and also the electrochemical performance. Among these three electrodes, the M1 electrode exhibits a high specific capacitance of 376 F g À1 at a current density of 5 mA cm À2 and a high specific energy of 52 W h kg À1, which is higher than M2 (specific capacitance 312 F g À1 and specific energy 43 W h kg À1) and M3 (specific capacitance 283 F g À1 and specific energy 39 W h kg À1 ) electrodes. Due to the interesting performance of the M1 based electrode, the symmetric device is fabricated using two electrodes M1 (3 : 1) and represented as SSM/M1//M1/SSM. The device provides a maximum specific capacitance of 87 F g À1 and specific energy density of 32 W h kg À1 at a current density of 5 mA cm À2. In addition, the symmetric device of the M1 electrode also exhibits good cycle stability showing 138%capacitance retention up to 2500 cycles. The enhanced electrochemical performance could be attributed to the direct growth of micro-flowers of MnO 2 on a stainless steel mesh, which provides more pathways for easy diffusion of electrolyte ions into the electrode. This study provides new insight and pathways for the development of low-cost and high-performance energy storage devices.
