Sodium-ion batteries (SIBs) have emerged as a promising alternative to lithium-ion (LIBs) due the abundant availability of sodium, lower costs, and comparable electrochemical performance characteristics. A thorough understanding their features is essential for widespread adoption application SIBs. Therefore, in this study, we investigate output characteristics impedance spectroscopy (EIS) sodium-ion under various states. The research results show that, unlike conventional lithium iron...

Abstract Membrane electrode assemblies (MEAs) were fabricated directly onto the electrolyte membrane, using an ultrasonic spraying technique. Pt–C catalysts, with concentrations of 10%, 20% and 40% by weight, used, Pt loading MEAs was kept constant at 0.3 mg cm −2 . Nafion contents considered from 15% to 35 wt.%. The morphologies evaluated scanning electron microscopy (SEM), in which agglomeration particles imaged, a secondary pore catalyst layers (CLs) revealed. cross‐section images showed...

Adsorption of SO(2) in the presence O(2) on Pt/C catalysts often used as electrocatalysts has been investigated by temperature programmed desorption (TPD) and X-ray photoelectron spectroscopy (XPS). The amounts adsorption were much higher than those absence (SO(2)-N(2)) from carbon support (Vulcan XC-72) alone. is dependent oxygen concentration over range 0-20% but reaches saturation at 20% O(2). spillover Pt to proposed for 10, 20, 40% loadings, characterized temperatures approximately 150...

Energy harvesting from road pavements was studied using thermoelectric generator (TEG) modules, where solar heat energy on the pavement transferred directly to electrical energy. Cement and asphalt were examined compared. The had better adsorption due its black surface. hot surface of TEG modules attached underside pavement, while cool enclosed by a cooling system. Natural airflow water-cooling systems investigated electromotive force (e.m.f.) voltages related temperature difference between...

The free but intermittent sources of energy such as photovoltaic and wind has become more popular nowadays. installation this type power source usually requires a secondary source, often the storage system battery to smoothen output over time. In article, we introduce, an alternative system, organic-electrolyte redox flow (RFB), which uses anthraquinone-2-sulfonic acid (AQS) 1,2-benzoquinone-3,5-disulfonic (BQDS) electrolytes. membrane is coated with Vulcan carbon using ultrasonic spray...

Aqueous organic redox flow batteries (AORFBs) are a type of battery that offers promising solution for energy storage, and one the main issues is selecting low-cost membranes with high ion conductivity to enhance performance efficiency. In this study, sulfonated poly ether ketone (SPEEK) were fabricated using casting method, polymer/solvent ratios SPEEK N,N'-dimethylformamide (DMF) being varied. The Nafion 117 membrane was used as benchmark comparison. aqueous employing...

Adsorption of SO2 on a Pt/C catalyst typically used in proton exchange- membrane fuel cells (PEMFCs) has been investigated by temperature programmed desorption (TPD). concentrations N2 were varied from 5 ppm to 1% (vol) and adsorption isotherms determined at 25, 50, 80 °C. Oxygen assisted (O-assisted) experiments (i.e., successive TPD following exposure room O2 after the first event) produced an additional peak higher than initial peak. These two types identified as weakly adsorbed species...

The gas phase synthesis of octahedral Pt3Ni/C electrocatalysts using several carbon substrates (Ketjen black, Graphene, and Vulcan XC-72R) was investigated. Different altered the morphology alloy Pt3Ni nanoparticles, with metal preferentially developing on Ketjen black while spherical shape bimetallic Vulcan. Furthermore, shown to be regulated throughout reduction process, H2:CO ratio playing a crucial role in controlling carrying out ORR activity. At 1:3 ratio, Pt3Ni/Ketjen exhibited...
