“…The semicircle's diameter determines the charge transfer resistance (R ct ), which is estimated to be 0.9 O after 10 cycles and 1.7 O after 5000 cycles. [49][50][51][52] The extremely low R ct values demonstrate that CrN@C NPs continue to exhibit significant electrical conductivity even after prolonged cycling. The extremely low R ct values demonstrate that CrN@C NPs continue to exhibit significant electrical conductivity.…”

Supercapacitors require efficient and environmentally friendly electrodes. This study investigates the promising potential of a tungsten oxide/silicon dioxide/tungsten oxide (WO3/SiO2/WO3) thin film on a Cu substrate as an alternative to conventional metal oxide flexible electrodes. Motivated by the need for enhanced energy storage capabilities, the WO3/SiO2/WO3 composite combines WO3 high specific capacitance and electrochemical stability of WO3 with improved mechanical durability and high surface area of SiO2, offering a synergistic solution to overcome electrode limitations. Utilizing the Radio Frequency (Rf) Magnetron Sputtering technique, the WO3/SiO2/WO3 thin film is precisely deposited on a Cu flexible substrate without organic additives, conductive agents, binder chemicals, or substrate pre‐treatment. Electrochemical characterization reveals the film’s pseudocapacitive behaviour, facilitated by the SiO2 interlayer, enabling influential adjustment of electrolyte ions within the electrode structure. The obtained high specific capacitances at various scan rates and current densities demonstrate the potential of the thin film for supercapacitor applications. This research highlights the nanosandwich WO3/SiO2/WO3 thin film as a promising material for flexible energy storage and intelligent nanodevices, making it a noteworthy candidate for various flexible applications. The findings contribute to the development of efficient and environmentally friendly energy storage solutions.This article is protected by copyright. All rights reserved.

“…The SC has various advantages over batteries, as it offers higher power densities, faster charging time, and longer cycling life. [1][2][3][4][5][6][7][8][9][10] As with batteries, SC devices are also composed of four main parts: positive and negative electrodes, a separator, and a suitable electrolyte. SC performance and cost are largely determined by electrode materials out of these four components.…”

The greater charge transfer rate and variable oxidation states make cerium oxides a potential candidate to be used for energy storage application. Also, doping heteroatom in the architecture of well‐structured cerium oxide can significantly improve capacitive performance. Herein, manganese doped cerium oxide‐based nanostructured thin film is synthesized via the pulse laser deposition method for the accomplishment of the supercapacitive performance of the electrode. Due to the incorporation of Mn into the lattice of CeO2 electrode, the specific capacitance has been increased from 292 to 395 F g−1 at 2 mA cm−2 and capacitance retention also increased to 92.5% in 0.5 m Li2SO4 electrolyte solution. Later, an Mn–CeO2//Mn–CeO2@SS device is fabricated, which exhibit a specific capacitance of 85 F g−1 at 2 mA cm−2 within the working voltage window of +1.2 V. The symmetric supercapacitor (SS) device with high energy and power densities of 31 Wh kg−1 and 1673 W kg−1, respectively, also exhibits excellent cyclic retention of 87.6% even after 10 000 cycles. The Mn‐doped CeO2 symmetric supercapacitor device's electrochemical richness makes it an appropriate material for supercapacitor applications.
