The vanadium redox flow battery (VRFB) is a rechargeable flow battery that is one of the most promising large-scale energy storage systems making it suitable for grid-level energy storage. However, the self-discharge reactions along with the undesired side reactions and water transfer through the membrane cause imbalance in the electrolyte and state of charge, which can significantly reduce the capacity of these batteries. A first-principles, 2D electrochemical dynamic model of all-VRFB is developed. The electrochemical model includes self-discharge reactions caused by diffusion, convection, and migration of the vanadium ions from one half-cell to the other. In addition, side reactions leading to evolution of hydrogen and oxygen are modeled. Water transport through the membrane is modeled by considering transport of water along with vanadium ions due to electro-osmotic drag and diffusion between two electrolyte half-cells. The model is validated with the experimental data. A filtering approach is developed for co-estimation of state of charge and capacity. Using a state-space model identified using the data generated by the pseudo-random binary sequence in the current and electrolyte flowrates, the filtering approach is found to yield satisfactory estimation of the state of charge and capacity by using voltage as the only measured output variable.

“…Lead (Pb) is among the most toxic heavy metals released into the environment, mostly from anthropogenic activities, such as vehicular traffic, mining, smelting, heating, and improper waste recycling and disposal (Natasha et al 2020). Lead ions entering the soil can be absorbed by plants or leached into the surface and ground waters and eventually accumulate in the human body through the food chain and water intake, causing various toxic effects on nervous, renal, digestive, and reproductive organs (Meena et al 2020).…”

Study of Pb desorption processes from clay minerals by chelating ligands is crucial to better understand the fate and transport of Pb in soil and sediment environments. In this study, Pb desorption from a Pb-loaded montmorillonite (MMT) was studied as affected by ethylenediaminetetraacetic acid (EDTA) and its two alternative eco-friendly chelating agents, i.e., methylglycine diacetic acid (MGDA) and glutamic-N,N-diacetic acid (GLDA) at two concentrations of 0.25 and 1.0 mM. The impacts of a 30-day residence time on the rate and quantity of Pb desorption were also evaluated. The result showed that Pb desorption kinetics was biphasic with an initial rapid phase, lasting for about 3 h, followed by a slow phase, lasting to 12 h. The degree of Pb desorption from Ca-MMT was proven to be governed by the nature and concentration of the chelating ligands presented in the systems. The capacity of the ligands to desorb Pb from Ca-MMT was in the order EDTA > > MGDA > GLDA, according to the decreasing order in the stability constants of their complexes with Pb ions. The aging of the MMT systems caused a significant reduction in both Pb desorption quantity and rate parameters. The results suggest that EDTA would have a more serious Pb-mobilizing impact than GLDA and MGDA in contaminated soil and sediments which contain Ca-MMT as a major clay constituent.

“…[13][14][15][16] Li-ion batteries, lead acid batteries and redox flow batteries, which are widely used, also have some disadvantages. [17][18][19][20][21][22] The fact that lithium material is a rare element and it is very scarce and its cost is increasing is seen as a serious problem. 23 Another problem that needs to be solved in Li-ion battery systems is the risk of explosion and fire.…”

“…24 Lead acid batteries have low energy density and are harmful to the environment, so their usage is declining. 18 Redox flow batteries have the advantage of high cycle life, but they still cannot answer some unknowns because they are not sufficiently developed commercially. 19 Supercapacitors are considered an energy storage system different from traditional methods.…”

In this study, nitrogen-doped graphene oxide(N-GO) and sulfur-doped graphene oxide(S-GO) were produced in one step, and two of these prepared materials were converted into composite form with polyaniline(PANI). For the first time in the literature, triple composite electrode materials with two heteroatom-doped graphene oxides and PANI were prepared for supercapacitors. In this context, heteroatom-doped graphene oxides and PANI were characterized using spectroscopic and microscopic methods. With the ternary composites formed, anode and cathode electrode materials for coin cell type supercapacitors in asymmetrical form were characterized by electrochemical methods. The capacitive behavior of the prepared supercapacitors was investigated by cyclic voltammetry and electrochemical impedance spectroscopy method. The change of capacitive behavior according to the number of cycles was determined by cyclic charge-discharge tests. With the electrode materials obtained with heteroatom doped graphene oxides/PANI composites, it reached the highest areal capacitance value of 79.7 mF.cm-2 at 10 mV.s-1 scan rate. The coin cell type asymmetric supercapacitors retained more than 100% of their initial specific capacitance at the end of the 1500 cycle.
