“…Hydrothermal processes are often combined with other methods due to several compelling reasons rooted in their synergistic benefits and enhanced material synthesis capabilities. 47,48 For example, Yang et al 49 fabricated a CoFe-LDH/NiFe-LDH heterostructure supported on nickel foam (NF) using hydrothermal and electrodeposition methods. Firstly, the CoFe-LDH/NF was formed by a one-pot hydrothermal process, and then the NiFe-LDH was grown onto the surface of the CoFe-LDH/NF using electrodeposition.…”

“…[1][2][3][4][5] Supercapacitors are mainly divided into double-layer capacitors and pseudocapacitors. [6][7][8] The capacitance of a pseudocapacitor is produced by a redox reaction at the electrode. The electrode materials commonly used are metal oxides and polymers.…”

Herein, a simple method to prepare porous carbon that inhibits hydrogen evolution is used, which has enormous advantages for both capacitors and lead‐acid batteries. The quantitative filter paper spongy porous carbon (SQFPC) is successfully synthesized by the two‐step method. SQFPC displays a porous, spongy structure with a large specific surface area (1847 m2 g−1). In electrochemical tests, SQFPC exhibits high specific capacitance (244 F g−1 at 1 A g−1) and a capacitance retention rate of 72.5% at 40 A g−1. In addition, the capacity of the battery with 0.5 wt% SQFPC is improved by 57.6% at a discharge rate of 0.1C, and the cycle life under the high‐rate partial state of charge is 9.3 times that of the blank battery. The enhanced battery performance is related to the unique structure and surface functional groups of carbon, which speed up ion movement inside the battery and provide active sites for lead deposition.

“…Manganese oxide has superior electrochemical performance than the other because it is mediated by reversible oxygen reduction [28,29] . The manganese oxide electrode has no commercial significance because of its low electrical conductivity, poor interfacial area, and inconsistent performance caused by the structure transition [30–34] . Mixed transition metal perovskite oxide has been presented as an alternative due to its structural stability and outstanding electrical conductivity [35] .…”

Energy‐saving strategies and programs have been developed by the appropriate organizations in response to rising concerns about the pollution created by fossil fuels in the environment. Compared to conventional batteries, supercapacitors have several advantages than other, including faster charge and discharge times, higher power density, a longer cycle life, and fever negative effects on the environment. Researchers explored perovskite as a novel class of eco‐friendly electrodes for energy conversion devices. In this study, we developed ZnMnO3 via a sol gel route for supercapacitor application. The phases, structure, valance, morphology and surface of the material are determined by X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and Brunauer Emmett Teller (BET), respectively. The electrochemical behavior manifested that the fabricated perovskite exhibited high capacitive efficiency of 889 F g−1 at 1 A g−1. The GCD stability test displays the highest capacitive retention of 97 % after 5000 cycles and shows prolong the stability of 50 h. Our findings suggest that the perovskite exhibited the fascinating feature for supercapacitor application to replace the other polluted source of energy.
