Ma, Yirui published the artcileUnderstanding the correlation between lithium dendrite growth and local material properties by machine learning, Safety of 2,5,8,11,14-Pentaoxapentadecane, the main research area is lithium metal battery dendrite growth neural network machine learning.

Lithium metal batteries are attractive for next-generation energy storage because of their high energy d. A major obstacle to their commercialization is the uncontrollable growth of lithium dendrites, which arises from complicated but poorly understood interactions at the electrolyte/electrode interface. In this work, we use a machine learning-based artificial neural network (ANN) model to explore how the lithium growth rate is affected by local material properties, such as surface curvature, ion concentration in the electrolyte, and the lithium growth rates at previous moments. The ion concentration in the electrolyte was acquired by Stimulated Raman Scattering Microscopy, which is often missing in past exptl. data-based modeling. The ANN network reached a high correlation coefficient of 0.8 between predicted and exptl. values. Further sensitivity anal. based on the ANN model demonstrated that the salt concentration and concentration gradient, as well as the prior lithium growth rate, have the highest impacts on the lithium dendrite growth rate at the next moment. This work shows the potential capability of the ANN model to forecast lithium growth rate, and unveil the inner dependency of the lithium dendrite growth rate on various factors.

Inoo, Akane published the artcileEffects of Solvation Structures on the Co-intercalation Suppression Ability of the Solid Electrolyte Interphase Formed on Graphite Electrodes, SDS of cas: 143-24-8, the main research area is graphite electrode SEI solvation structure cointercalation suppression ability.

The effect of solvation structures on solvated Li+ migration in a solid electrolyte interphase (SEI) was investigated using glyme-solvated Li+ as probes for co-intercalation reactions. The intercalation of bare Li+ into graphite occurred in the presence of the SEI derived from vinylene carbonate and when Bu Me triglyme was the solvent. Based on the results of d. functional theory calculations, both the size of solvated Li+ and the width of the ionic path of SEIs are crucial to determine whether Li+ is desolvated.

Jozwiak, Malgorzata published the artcileHeat capacity of six glymes in N,N-dimethylformamide + water mixtures. Solvation of glymes, Related Products of ethers-buliding-blocks, the main research area is glymes DMF water mixture solvation heat capacity.

The paper presents the heat capacities of glyme solutions: monoglyme, diglyme, triglyme, tetraglyme, pentaglyme and hexaglyme, in binary solvents N,N-dimethylformamide + water at four temperatures (293.15 K, 298.15 K, 303.15 K, 308.15 K) obtained using differential calorimeter Micro DSC III, Setaram – France. The concentration of glymes was approx. 0.25 mol/kg. On the basis of the obtained exptl. results, the apparent isobaric heat capacities of the glymes were calculated It was noted that the larger the glyme mol. was, the more pronounced the increase in the value of the apparent molar heat capacity function with the increase in water content in the two-component solvent. The observed changes in apparent isobaric heat capacity as a function of the water content in the mixed solvent are discussed in terms of the hydrophobic nature of the glymes. Moreover, it was shown that the apparent molar isobaric heat capacity of the glymes in pure solvents, i.e. in water and in N,N-dimethylformamide, increases linearly with the increase in the number of oxygen atoms in the glyme mols. i.e. with the size of glyme mols. Furthermore, a linear correlation was observed between the apparent isobaric molar heat capacity and the enthalpic effect of the hydrophobic hydration of the studied glymes at 298.15 K. The results obtained in this paper are compare with the same obtained for selected cyclic ethers.

Kwak, Won-Jin published the artcileOptimized Electrolyte with High Electrochemical Stability and Oxygen Solubility for Lithium-Oxygen and Lithium-Air Batteries, Product Details of C10H22O5, the main research area is lithium air oxygen battery electrolyte electrochem stability solubility.

Lithium-oxygen (Li-O2) batteries with high reversibility require a stable electrolyte against the side reactions with Li-metal anode and reactive oxygen species. Moreover, an electrolyte that can effectively utilize the low partial pressure of oxygen in the atm. has significant effect on the practical application of Li-air batteries. In this study, a localized high-concentration electrolyte (LHCE) was developed using 1H,1H,5H-octafluoropentyl 1,1,2,2-tetrafluoroethyl ether (OTE) as a diluent, which satisfies all these conditions simultaneously. The OTE-based LHCE exhibits much improved electrochem. performance in Li-O2 batteries and Li-air batteries in comparison to the conventional electrolyte and high-concentration electrolyte. The design principles of this electrolyte also provide important guidelines for research to further develop new electrolytes for Li-O2 and Li-air batteries.

Arai, Nana published the artcileDynamic Chelate Effect on the Li+-Ion Conduction in Solvate Ionic Liquids, Computed Properties of 143-24-8, the main research area is glyme chain length lithium conductivity solvate ionic liquid.

Lithium-glyme solvate ionic liquids (Li-G SILs), which typically consist of a lithium-ion (Li+) solvated by glymes of oligoethers and its counter anion, are expected as promising electrolytes for lithium secondary batteries. Addnl., a specific ligand-exchange Li+ conduction mechanism was proposed at the electrode/electrolyte interface of the cell using Li-G SILs. To reveal Li+ conduction in SILs, Li-G SILs with varying ethylene oxide chain lengths were investigated using various techniques that are sensitive to solution structure and dynamics. We found good correlations between the relaxation time of the slowest dielec. mode and the ionic conductivity as well as viscosity. We propose that a dynamic chelate effect, which is closely related to solvent exchange and/or contact ion-pair formation/dissociation, is important for Li+ conduction in these Li-G SILs.

Marques Mota, Filipe published the artcileRevisiting Solvent-Dependent Roles of the Electrolyte Counteranion in Li-O2 Batteries upon CO2 Incorporation, Application of 2,5,8,11,14-Pentaoxapentadecane, the main research area is revisiting solvent dependent roles electrolyte counteranion lithium oxygen battery.

Lithium-oxygen batteries are promising next-generation high-energy storage candidates. Replacing pure O2 with air and uncovering moisture and CO2-contamination effects on the O2 electrochem., however, represent necessary steps toward commercialization. Representatively, a CO2-induced shift toward Li2CO3 formation has been systematically disclosed in a number of electrolyte solvents. Here, we show that in tetraglyme only Li2CO3 is formed without Li2O2. Using explicit theor. calculations, we reveal that discharge is governed by the strong chelation effect induced by oxygen lone electron pairs of the glyme, which emphasizes the importance of assessing direct interat. interactions between Li+ and solvent mols. when determining preferred reaction pathways in these O2/CO2 systems. The choice of the electrolyte counteranion investigated here for the first time, however, has no apparent effect on the O2/CO2 electrochem., leading to Li2CO3. Galvanostatic results and product analysisnonetheless reveal that highly dissociated Li+ counteranions in tetraglyme favorably stabilize soluble peroxocarbonate reaction intermediates during discharge, whereas highly associated salts accelerate Li2CO3 precipitation, dramatically narrowing the cell capacity. Importantly, these observations are also distinct from prior conclusions from rationally designed electrolytes under pure O2 conditions and emphasize the need to revisit established correlations between uncovered counteranion···Li+···solvent interaction degrees and the balance between mechanistic pathways in practical Li-air devices.

Bawol, Pawel Peter published the artcileUnraveling the Mechanism of the Solution-Mediated Oxygen Reduction in Metal-O2 Batteries: The Importance of Ion Association, Synthetic Route of 143-24-8, the main research area is lithium peroxide potassium superoxide metal oxygen battery reduction.

One of the bottlenecks in Li-O2 batteries is the film like growth of Li2O2 on the electrode surface during discharge leading to early cell death. To tackle this problem 2,5-Di-tert-1,4-benzoquinone (DBBQ) was introduced as a soluble redox mediator. This redox mediator is avoiding the Li2O2 layer-by-layer growth on the electrode surface and thus leading to higher discharge capacities of the Li-O2 cell. In this study, we investigate the ion pairing between the cation of the conducting salt and the DBBQ monoanion and the resulting impact on the ORR activity of the DBBQ monoanion. We investigate TBA+, K+ and Li+ as cations and TEGDME and DMSO as solvents. We found out that there is a direct correlation between the ORR activity of DBBQ- and the ion pairing of DBBQ- with the cation of the supporting electrolyte: Only if DBBQ is strongly associated with the cations of the electrolyte it will reduce oxygen in the electrolyte. Increasing the Li+ concentration in the electrolyte shifts the ORR potential to more pos. electrode potentials. In addition, we are describing a new exptl. approach to investigate the kinetics of the homogenous ORR via time resolved mass spectrometry. With this approach we found out, that the reaction Li-DBBQ(sol)+O2(sol)k1⇌k-1Li-DBBQ-O2(sol) is 80 times faster in a TEGDME based electrolyte than in a DMSO-based electrolyte. We determined k1 with 5.1 102 s-1 M-1and k-1 with 3.7 102 s-1 M-1 in TEGDME whereas the constants in DMSO are k1 = 4.5 s-1 M-1 and k-1 = 5.5 s-1 M-1s.

Drews, Janina published the artcileModeling of electron-transfer kinetics in magnesium electrolytes: Influence of the solvent on the battery performance, Product Details of C10H22O5, the main research area is electron transfer kinetics magnesium ion secondary battery electrolyte; Computational chemistry; Deposition mechanism; Desolvation; Kinetics; Rechargeable magnesium batteries.

The performance of rechargeable magnesium batteries is strongly dependent on the choice of electrolyte. The desolvation of multivalent cations usually goes along with high energy barriers, which can have a crucial impact on the plating reaction. This can lead to significantly higher overpotentials for magnesium deposition compared to magnesium dissolution In this work we combine exptl. measurements with DFT calculations and continuum modeling to analyze Mg deposition in various solvents. Jointly, these methods provide a better understanding of the electrode reactions and especially the magnesium deposition mechanism. Thereby, a kinetic model for electrochem. reactions at metal electrodes is developed, which explicitly couples desolvation to electron transfer and, furthermore, qual. takes into account effects of the electrochem. double layer. The influence of different solvents on the battery performance is studied for the state-of-the-art magnesium tetrakis(hexafluoroisopropyloxy)borate electrolyte salt. It becomes apparent that not necessarily a whole solvent mol. must be stripped from the solvated magnesium cation before the first reduction step can take place. For Mg reduction it seems to be sufficient to have one coordination site available, so that the magnesium cation is able to get closer to the electrode surface. Thereby, the initial desolvation of the magnesium cation determines the deposition reaction for mono-, tri- and tetraglyme, whereas the influence of the desolvation on the plating reaction is minor for diglyme and THF. Overall, we can give a clear recommendation for diglyme to be applied as solvent in magnesium electrolytes.

Jankowski, Piotr published the artcileDesigning High-Performant Lithium Battery Electrolytes by Utilizing Two Natures of Li+ Coordination: LiTDI/LiTFSI in Tetraglyme, COA of Formula: C10H22O5, the main research area is tetraglyme lithium battery electrolyte spectrum.

Highly concentrated electrolytes (HCEs) based on glymes, such as tetraglyme (G4), are currently the focus of much battery research, primarily due to their unique properties – especially with respect to ion transport and electrochem. stability. While the LiTFSI-G4 and LiTDI-G4 systems both have been studied extensively, we here design their hybrid electrolytes to answer; will the resulting properties be averages/superpositions or will there be synergies created We find the latter to be true and demonstrate that the most performant electrolytes are obtained by introducing a minor amount of LiTDI to an LiTFSI based electrolyte, which promotes the disproportionation and formation of “”free”” cations and at the same to avoid large aggregates – shown comprehensively both exptl. and by different modeling approaches and analyses combined. This electrolyte composition strategy can be generalized to other salts and solvents and thus a route towards a flora of novel battery electrolytes is here suggested.

Lv, Zhiqiang published the artcileSolvation structure and solid electrolyte interface engineering for excellent Na+ storage performances of hard carbon with the ether-based electrolytes, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is solvation structure solid electrolyte interface engineering excellent sodium storage.

Compared with the commonly used ester-based electrolytes, more excellent Na+ storage performances can be achieved for hard carbon in the ether-based electrolyte. Whereas, the mysteries underlying such excellent electrochem. performances are still unclear. Herein, the impressive Na+ storage behaviors of hard carbon in the ether-based electrolyte were clarified based on a profound insight of Na+ storage mechanism. It’s revealed that the co-intercalation behavior is responsible for the lower de-solvation energy, which contributes to a facile de-solvation process and the enhanced charge transfer kinetic. Besides, a thin, amorphous and flexible solid-electrolyte interface (SEI) in ether-based electrolyte with a specific structure where the amorphous nanoparticles are coated with organic species was probed. And the resulted SEI is beneficial to achieving much lower activation energy for Na+ diffusion through SEI and a stable interface during cycling due to its excellent ion-conducting ability and mech. flexibility. It’s also demonstrated that ether-based solvent with short chain length plays a pos. impact on the Na+ storages, which also well agrees with the above synergistic effect. The research plays a significant role in elucidating the uniqueness of ether-based electrolytes to hard carbon and promoting its practical application in future sodium-based battery chemistries.
