Supercapacitors can achieve both high energy and power density through the use of efficient electrode materials which have a significant impact on their performance. In this study, for the first time, in order to improve the electrochemical properties of the electrodes, we applied an electric field to the biomass-based activated carbon obtained by activation-carbonization. We also examined the effect of applied electric field strength and duration on the electrochemical properties of the electrodes by preparing five different materials. The properties of the produced materials were tested by different chemical characterization and electrochemical methods. Thanks to the electrical activation, the material’s surface area, pore volume, and pore diameters were increased, the capacitance value has increased to 295 F/g, which was 89 F/g as a result of activation–carbonization. The EFQ-4 supercapacitor has a maximum energy density of 20.49 Wh kg⁻¹ at a power density of 526.28 W kg⁻¹, and the energy density value is far superior to the energy densities of the supercapacitors located on the Ragone plane. In addition, the electric field made the material more stable, improved the cycle life, and increased the stability from 92.10 to 95.50%. The electrochemical results of the produced electrodes are promising in the field of energy storage.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142519022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For safety, it is essential to develop fast, selective and highly sensitive hydrogen detectors for any practical applications and the metal oxide-based chemiresistive gas sensors are the front-runners due to their compatibility with the electrical circuits and current semiconductor technology. This work presents excellent hydrogen sensing performance of magnetron-sputtered pure SnO₂ thin film-based sensors. The effect of deposition temperature on structure and hydrogen (H₂) gas-sensing properties of SnO₂ thin film is discussed. The maximum response 57.41% (500 ppm) is obtained at lower operating temperature of 200 °C for a sensor deposited at 125 °C. The response/recovery time of the sensor are found to be remarkably fast 50 s/39 s for 5 ppm concentration of hydrogen gas. The detection limit (DL) of the sensor as liner fit is 129.27 ppb. The stability and selectivity in humid conditions were also investigated and the sensor's response is found stable up to humidity of 40% RH. Sensor shows good selectivity toward H₂ gas in dry air and high humidity level 80% RH. The experimental results are explained and supported by simulation studies using the Crowell-Sze model in Finite-Difference Time-Domain (FDTD) simulations on the COMSOL Multiphysics platform.

The process of acid-functionalization of MWCNTs with nitric acid has been discussed. The acid-functionalization of MWCNTs introduces carbonyl (C=O) and hydroxyl (–OH) groups, attributed to carboxyl (–COOH) groups on their surfaces, as confirmed by Fourier transform infrared analysis.

Rheological characterization showed that the inks formulated exhibited shear-thinning behavior, making them satisfactory for application in DIW.

Lithium sulfur batteries (LSBs) satisfy both criteria but their practical implementation is marred by the highly resistive nature of sulfur. Carbon-based cathodes play a vital role in mitigating the issue because their high conductivity allows for effective electron transfer during electrochemical cycling. Synthesis and electrochemical evaluation of carbon-based cathodes from two different sources for LSBs was carried out. Herein, two kinds of carbon, namely bio-derived carbon from coconut shells (CC500) and N-doped carbon (NC) from polyacrylonitrile fibers were synthesized and sulfur was incorporated via the melt diffusion route. The composites are characterized by PXRD and TGA, which determined 80 wt% mass loading of sulfur. The higher intensity of G-band over D-band in Raman spectroscopy indicates greater graphitic character for CC500 compared to NC. SEM images show large macro-pore like tunnels in CC500 while NC appears are irregular chunks. EDAX spectra showed 20 wt% N content in NC while CC500 is largely carbon with some minor surface oxygen.
