Abstract:

In this study, three slots containing an anode chamber, a cathode chamber, and a middle pole chamber were designed by applying the Hittorf method, and a two-way coupling model of the flow field and electric field was established using the COMSOL system. The electric field distribution in the constructed model was simulated, and the model reliability, boundary conditions, and related parameters were verified. A three-chamber tank was utilized to investigate the migration numbers change rule and migration mechanism of Y(III) ions in the AlF3–(Li,Na)F system. The migration number of Y(III) ions i

Abstract:

Electrochemical behaviors of Ti(III) ions and electrodeposition of Ti were investigated in molten AF–ACl–A3TiF6 (A = Li, Na, K) at 973 K. Redox currents corresponding to Ti(III)/Ti(0) and Ti(IV)/Ti(III) reactions were observed by cyclic voltammetry. The redox potentials of the reactions with reference to Cl2/Cl− and F2/F− were most positive for the Li system, followed by the Na system, and most negative for the K system. The differences in the potential can be explained by the interactions of alkali cations and F- ions; smaller cations interact more strongly with F−, resulting in a weaker inte

The interaction process between a series of cyclopeptide compounds cyclo(Gly)n (n=4,6,8)and monovalent ions (Li+, Na+, K+, F−, Cl−, and Br−) was studied using theoretical calculation.

It was found that for the same cyclopeptide the binding energy has the order of cyclo(Gly)n–Li+> cyclo(Gly)n–Na+> cyclo(Gly)n–K+and cyclo(Gly)n–F−> cyclo(Gly)n–Br−> cyclo(Gly)n–Cl−.

Light scattering at 546 nm, which is mainly related to the presence of rodlike particles longer than 50 nm, showed that Li+ accelerates the formation of actin filaments. Intermolecular cross-linking with N,N′-1,4-phenylene-bismaleimide proved that the observed enhancement in the light-scattering intensity is caused by the increase in the concentration of actin oligomers, which gradually elongate to form longer filaments. DNase-I-related F-actin disassembly was reduced in the presence of lithium ions, as demonstrated by fluorimetric and viscometric experiments. Li+–F-actin showed an apparently

Abstract:

The electrical conductivity has been measured for the glasses in the system B2O3–Li2O–Li2X2(X = F, Cl, Br), where Li2O is replaced by Li2X2 with Li content kept constant. The conductivity decreases for F glasses and increases for Cl and Br glasses with increasing halide ion content, which is caused by the increase in the activation energy for F glasses and the decrease for Cl and Br glasses. The analysis of the activation energy in terms of the Anderson-Stuart model indicates that, with the increase in LiX, Δ Eb, (the electrostatic energy) increases for F glass, whereas ΔEs (the strain energy)

In this work, we study the diffusion characteristics and structure of the molten salt FLiNaK with dissolved CeF3 in the operating temperature range of the molten-salt reactor. The temperature dependence of the self-diffusion coefficients of the ions that make up the salt mixture is represented with good accuracy as a linear dependence, except for the case of self-diffusion of Ce ions. As a rule, Li and F ions are more mobile than Na and K ions and significantly more so than slow Ce ions.

Abstract:

The energies and heats of ion-molecule reactions have been calculated (MP4/6-31G**//6-31G** or better level) and compared with the experimental values obtained from the heats of formation. Two main types of reactions have been studied: (i) AHn + AHn+• ↔ AHn+1+ + AHn-1• (A = C to F and Si to Cl), (ii) AHn + BHm+• ↔ AHn+1+ + BHm-1• or AHn-1+• + BHm+1+ (A and B = C to F). In contrast to (i), processes of type (ii) permit easy differentiation between the proton transfer and hydrogen atom abstraction mechanisms. A third type of interaction involves reactions with radical anions (A = Li to F); compa

Abstract:

Layered-type Li-rich cathode materials have attracted significant attention for the next generation Li-ion batteries, but their poor reversibility in terms of both voltage and capacity upon cycling are as prominent as their high capacity. Irreversible oxygen redox activity and surface deterioration have been deemed as the root cause and direct cause for their poor performance, respectively. To mitigate those issues, we introduce substantial amounts of oxygen vacancies into layered-type Li1.2Ni0.2Co0.2Mn0.4O2 by using CaH2 as a reduction agent. Reduced samples show higher reversible capacity du

Abstract:

F-doped LiFePO4/C cathode materials were synthesized by two-step solid-state reaction route. The F-doped LiFePO4/C increases the intrinsic conductivity, the diffusion of lithium ions, also improves the high-rate and low-temperature performances of LiFePO4. The SEM images reveal some small morphology changes of the two kinds of the materials, so the improved properties may not due to grain size changes but crystal structure changes. The F-doped material has a higher capability at low temperature. At -20°C, with the rate of 0.5C, the discharge capacity was 82mAhg-1, higher than that of undoped m

Abstract:

Unstable Li metal/solid polymer electrolyte (SPE) interface, or solid electrolyte interface (SEI), limits applications of SPEs in lithium metal batteries (LMBs). Arising from ultrahigh Li reducibility, parasitic reactions (for instance, reaction of Li with PEO to form C2H4, Li2O, and H2) inevitably take place at Li/PEO interface, harming the electrochemical performances of LMBs. Additionally, during the battery operation, the Li/SPE interface continuously thickens due to the repeated reactions between the Li metal and fresh SPE, leading to uneven surface morphology and large electrochemical im

Abstract:

The reversible and electrochemical reactions for the formation of graphite intercalation compounds (GICs) are fundamental to their use as electrode reactions in rechargeable batteries. A common practical application is the electrochemical intercalation and de-intercalation of Li+ ions within graphite electrodes of lithium-ion batteries (LIBs). Similarly, dual-graphite batteries (DGBs) employ GIC formation reactions and operate through the intercalation and de-intercalation of both cations and anions at the negative and positive electrodes, respectively, during charging/discharging processes.

Due to great interest in the development of electric vehicles and other applications, improving the performances of lithium-ion batteries (LIBs) is crucial. Specifically, components of electrolytes for LIBs should be adequately chosen from hundreds of thousands of candidate compounds.

That is, the viscosity, ionic conductivity, degree of dissociation, diffusion coefficient, and conformation of each molecule were analyzed via molecular dynamics (MD) si

A novel Coulomb spike concept is applied to the radiation damage induced in LiF and SiO2 with about the same mass density (~2.65 g cm−3) by Ni2860 and Kr3684 ions of 1.0-MeV u−1 energy for about the same electronic energy loss (~10 MeV µm−1). This is an alternative concept to the already known models of the Coulomb spike and inelastic thermal spike for the damage induced by swift heavy ion irradiations. The distribution of ionizations and electrostatic energy gained in the electric field by the ionized atoms is computed with the PHITS code for both targets. Further, the atomic collision cascad
