Schmidt, Florian published the artcileSolvate Cation Migration and Ion Correlations in Solvate Ionic Liquids, Computed Properties of 143-24-8, the main research area is solvate cation migration lithium tetrafluoroborate bistrifluoromethanesulfonylimide ionic liquid tetraglyme; electrophoretic NMR solvate cation migration lithium ionic liquid tetraglyme.

Lithium salt-glyme mixtures are interesting candidates as electrolytes for battery applications. Depending on the type of glyme or anion and the salt concentration, they either show ionic liquid-like behavior with stable lithium-glyme complex cations or concentrated salt solution-like behavior. Here, we apply electrophoretic NMR (eNMR) to elucidate transport mechanisms by observing the migration of the mol. species in an elec. field. We investigate two solvate ionic liquids, i.e., lithium bis(trifluoromethanesulfonyl)amide (LiTFSA) and lithium tetrafluoroborate (LiBF4), in tetraglyme (G4) at different glyme-salt molar ratios X. A field-induced migration of neutral glyme mols. is directly observed, which is due to stable solvate-Li complex formation. Transference numbers, effective charges, and ionicities are derived from electrophoretic mobilities and self-diffusion coefficients, resp., for the nuclei 1H, 7Li, and 19F. The effective charges are the highest at the equimolar mixture, X = 1, they differ strongly for lithium and anion, and they show large differences between both systems. These findings are qual. interpreted in a speciation model, suggesting anionic clusters and solvate cations as the species dominating charge transport. The resulting effective charges can only be explained taking into account ion-ion anti-correlations in the framework of the Onsager formalism, where anti-correlations between the solvate cation and the anionic complexes arise due to momentum conservation. The contributions to the anti-correlation are most dominant at high salt concentrations and in the system with the LiBF4- anion due to its lower mass and ability to form larger asym. clusters with Li+. Thus, in either system, also the lithium transference number is influenced to a different extent by ion-ion anti-correlations.

Celik Kucuk, Asuman published the artcileEffects of LiBOB on salt solubility and BiF3 electrode electrochemical properties in fluoride shuttle batteries, Quality Control of 143-24-8, the main research area is bismuth fluoride lithium bisoxalatoborate salt electrode electrochem shuttle battery.

In this study, lithium bis(oxalato)borate (LiBOB) was used for the first time in a fluoride shuttle battery (FSB) to overcome the solubility problem of fluorine-based salts typically present in organic solvents. For this purpose, tetraglyme (G4) electrolytes containing CsF salt and LiBOB with three different concentrations (LiBOB0.06/CsF/G4, LiBOB0.25/CsF/G4, and LiBOB0.5/CsF/G4) were prepared The effects of LiBOB on the electrochem. compatibility of the bismuth fluoride pos. electrode were examined by cyclic voltammetry, charge-discharge tests, and a.c. impedance measurements. The related discharge and charge reactions were confirmed by X-ray diffractometry, whereas 19F NMR and Raman spectroscopies were used to detect potential interactions in the various LiBOB/CsF/G4 systems. At the lowest and highest LiBOB concentrations (i.e., in LiBOB0.06/CsF/G4 and LiBOB0.5/CsF/G4, resp.), the electrolyte decomposition was dominant, whereas the intermediate concentration in LiBOB0.25/CsF/G4 was found to be the optimum condition and played a critical role in CsF solubility, allowing a successful fluoride shuttle-based redox reaction.

Ge, Aimin published the artcileUnraveling the Unstable Nature of Tetraglyme-Based Electrolytes toward Superoxide and the Inhibitory Effect of Lithium Ions by Using In Situ Vibrational Spectroscopies, Application In Synthesis of 143-24-8, the main research area is tetraglyme electrolyte superoxide lithium oxide battery.

The stability of solvents is critical for the efficiency and cyclability of rechargeable aprotic lithium-oxygen (Li-O2) batteries. Here, we report a combined spectroscopic study on the stability of tetraglyme (G4), which is one of the most commonly used solvents in Li-O2 batteries, against superoxide (O2-) during oxygen reduction reaction (ORR). Based on sum-frequency generation spectroscopy characterization, we found that ORR induces significantly irreversible structural changes in G4 mols. on the electrode surface in an O2-saturated Li+-free solution In the Li+-containing solution, however, reversibility for the structural change in G4 mols. is primarily improved. Furthermore, IR reflectance absorption spectroscopy and surface-enhanced Raman spectroscopy measurements confirmed that G4 is extremely unstable during ORR in the Li+-free G4 solution In addition, several decomposition products have been identified during ORR. On the other hand, the decomposition of G4 during ORR is significantly suppressed when Li+ is included in the solution These results indicate that O2- plays a crucial role in the cathodic decomposition of the G4 solvent during ORR. The decomposition mechanism and the inhibitory effect of Li+ are discussed based on spectroscopic observations.

Hashimoto, Kei published the artcileDesign of polymer network and Li+ solvation enables thermally and oxidatively stable, mechanically reliable, and highly conductive polymer gel electrolyte for lithium batteries, Formula: C10H22O5, the main research area is design polymer network li solvation enables thermally oxidatively stable.

Herein, we demonstrate that design of polymer network and Li+-ion solvation enables the fabrication of thermally and oxidatively stable, mech. reliable, and highly conductive polymer gel electrolytes for lithium batteries. Polymer gel electrolytes have been used for Li-ion batteries (LIB) due to their quasi-solid natures and flexible shapes. However, they frequently suffer from the high vapor pressures of the incorporated solvents, low oxidative stabilities, and poor mech. properties. To overcome these drawbacks, we fabricated a tough gel electrolyte comprising a tetra-arm poly(ethylene glycol) (TPEG) homogeneous polymer network, in which a tetraglyme(G4)-based solvate ionic liquid (SIL) was incorporated. It was intriguing to find that the solvation of Li+ ion by oxygen atoms (within G4 and TPEG), represented as [O]/[Li], governed the thermal and oxidative stabilities of the gel electrolyte, while the homogeneous network contributed to the mech. reliability and high ionic conductivity At [O]/[Li] = 5, the TPEG-based gel electrolyte with no free solvent simultaneously exhibited high thermal (>200°C) and oxidative stabilities (>4.4 V), high stretchability, and high ionic conductivity (~1 mS cm-1 at 30°C). These favorable properties of the gel electrolyte resulted in reversible charge/discharge of a 4-V-class high-voltage cathode (LiNi0.6Mn0.2Co0.2O2, NMC622).

Kunanusont, Nattanai published the artcilePorous Carbon Cathode Assisted with Ionogel Binder Fabricated from Supercritical Fluid Technique toward Li-O2/CO2 Battery Application, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is ionic liquid ionogel binder porous carbon cathode; lithium oxygen battery supercritical carbon dioxide.

Lithium-O2/CO2 battery has been recently developed due to its higher capacity than Li-O2 battery and high impact on energy and environmental problems. Ionogels composed of ionic liquid ([bmim][Tf2N], [bmim][PF6] or [bmim][I]), and poly(vinylidene fluoride) (PVDF) is applied as a binder of carbon particles on cathode of Li-O2/CO2 battery. A porous carbon cathode with ionogel binder was fabricated by drying and impregnation techniques in supercritical carbon dioxide at 40°C and 20.0 MPa. The effect of ionic liquid on cathode properties was investigated by various ratios of ionic liquid amount in the ionogel binder. The porous carbon cathodes were further used to test the discharge capacity of Li-O2/CO2 batteries. We found that the capacity of battery was enhanced as the amount of ionic liquid in the gel binder increased, while the cathode with PVDF-[bmim][Tf2N] ionogel binder had the highest discharge capacity at 15.07 mAh cm-2. The mechanism of capacity enhancement relies on the reduction of interfacial resistance between electrolyte and cathode and the improvement of reaction gases solubilities into the ionogel binder on the porous carbon cathode.

Huang, Lulu published the artcileYucca-like CoO-CoN Nanoarray with Abundant Oxygen Vacancies as a High-Performance Cathode for Lithium-Oxygen Batteries, Application of 2,5,8,11,14-Pentaoxapentadecane, the main research area is lithium oxygen battery yucca like array cathode catalyst.

In this paper, we report a three-dimensional, yucca-like CoO-CoN composite cathode prepared by the in situ growth of a Co(OH)F array on pretreated carbon paper, followed by controllable partial nitridation in ammonia flow. The material exhibited excellent oxygen reduction and evolution activity and, in particular, excellent cathode performance for aprotic Li-O2 batteries. Our optimal sample yielded a specific capacity of up to 5423 mA h g-1 and functioned for 200 cycles with no degradation It was found that the introduction of oxygen vacancies on the surface of CoO-CoN through nitridation played a crucial role in the material’s high performance, especially its high stability and long cyclability. We attribute the high performance to the following: first, the material’s nanoarray architecture, which provided a large surface area and featured enough interspaces to ensure a high d. of active sites as well as to assist with oxygen and ion diffusion, and with the hosting of discharge products, and second, the abundant oxygen vacancies generated on the CoO-CoN surface during partially controlled nitridation, which significantly enhanced the material’s oxygen reduction/evolution reaction activity and stability.

Oh, Gwangseok published the artcileSeed Layer Formation on Carbon Electrodes to Control Li2O2 Discharge Products for Practical Li-O2 Batteries with High Energy Density and Reversibility, Related Products of ethers-buliding-blocks, the main research area is carbon electrode lithium oxide oxygen battery; Li2O2; carbon electrode; interface; lithium air battery; nucleation; seed layer.

The high theor. energy densities of lithium-air batteries (LAB) make this technol. an attractive energy storage system for future mobility applications. Li2O2 growth process on the cathode relies on the surrounding chem. environment of electrolytes. Low conductivity and strong reactivity of Li2O2 discharge products can cause overpotential and induce side reactions in LABs, resp., eventually leading to poor cyclability. The capacity and reversibility of LABs are highly susceptible to the morphol. of the Li2O2 discharge products. Here, we identify for the first time that a seed layer formed by the combination of a cathode and an electrolyte determines the morphol. of Li2O2 discharge products. This seed layer led to its high reversibility with a large areal capacity (up to 10 mAh/cm2). Excellent OER (oxygen evolution reaction) was achieved by the formation of a favorable interface between the carbon electrode and electrolyte, minimizing the decomposition of the electrolyte. These remarkable improvements in LAB performance demonstrate critical progress toward advancing LAB into practical uses, which would exploit good reversibility of LABs in pouch-type cell arrangements with 1.34 Ah.

Jiang, Yongxiang published the artcileMildly Oxidized MXene (Ti3C2, Nb2C, and V2C) Electrocatalyst via a Generic Strategy Enables Longevous Li-O2 Battery under a High Rate, Product Details of C10H22O5, the main research area is sodium ion battery cathode oxidized MXene electrocatalyst; Li−O2 battery; electrocatalysts; high current density; longevous; mildly oxidized MXene.

Lithium-oxygen batteries (LOBs) with ultrahigh theor. energy d. have emerged as one appealing candidate for next-generation energy storage devices. Unfortunately, some fundamental issues remain unsettled, involving large overpotential and inferior rate capability, mainly induced by the sluggish reaction kinetics and parasitic reactions at the cathode. Hence, the pursuit of suitable catalyst capable of efficiently catalyzing the oxygen redox reaction and eliminating the side-product generation, become urgent for the development of LOBs. Here, we report a universal synthesis approach to fabricate a suite of mildly oxidized MXenes (mo-Nb2CTx, mo-Ti3C2Tx, and mo-V2CTx) as cathode catalysts for LOBs. The readily prepared mo-MXenes possess expanded interlayer distance to accommodate massive Li2O2 formation, and in-situ-formed light metal oxide to enhance the electrocatalytic activity of MXenes. Taken together, the mo-V2CTx manages to deliver a high specific capacity of 22752 mAh g-1 at a c.d. of 100 mA g-1, and a long lifespan of 100 cycles at 500 mA g-1. More impressively, LOBs with mo-V2CTx can continuously operate for 90, 89, and 70 cycles, resp., under a high c.d. of 1000, 2000, and 3000 mA g-1 with a cutoff capacity of 1000 mAh g-1. The theor. calculations further reveal the underlying mechanism lies in the optimized surface, where the overpotentials for the formation/decomposition of Li2O2 are significantly reduced and the catalytic kinetics is accelerated. This contribution offers a feasible strategy to prepare MXenes as efficient and robust electrocatalyst toward advanced LOBs and other energy storage devices.

Liu, Dezhong published the artcileStable Room-Temperature Sodium-Sulfur Batteries in Ether-Based Electrolytes Enabled by the Fluoroethylene Carbonate Additive, SDS of cas: 143-24-8, the main research area is stable room temperature sodium sulfur battery ether electrolytes enabled; cathode−electrolyte interphase; electrolyte additive; room-temperature sodium−sulfur batteries; sulfurized polyacrylonitrile cathode; “solid−solid” conversion.

Because of its high energy d. and low cost, the room-temperature sodium-sulfur (RT Na-S) battery is a promising candidate to power the next-generation large-scale energy storage system. However, its practical utilization is hampered by the short life span owing to the severe shuttle effect, which originates from the “”solid-liquid-solid”” reaction mechanism of the sulfur cathode. In this work, fluoroethylene carbonate is proposed as an additive, and tetraethylene glycol di-Me ether is used as the base solvent. For the sulfurized polyacrylonitrile cathode, a robust F-containing cathode-electrolyte interphase (CEI) forms on the cathode surface during the initial discharging. The CEI prohibits the dissolution and diffusion of the soluble intermediate products, realizing a “”solid-solid”” reaction process. The RT Na-S cell exhibits a stable cycling performance: a capacity of 587 mA h g-1 is retained after 200 cycles at 0.2 A g-1 with nearly 100% Coulombic efficiency.
