Liang, Dong published the artcileInhibiting the shuttle effect using artificial membranes with high lithium-ion content for enhancing the stability of the lithium anode, Computed Properties of 143-24-8, the main research area is graphene oxide polystyrene sulfate lithium oxygen battery stability.

The low cycle stability of the lithium anode has become one of the bottlenecks restricting the development of lithium-metal batteries with high theor. energy d. Serious side reactions between lithium and electrolyte components are one of the key reasons for the poor cycle stability of the lithium anode. Herein, lithiated graphene oxide (GO-Li) and lithium poly(styrene sulfate) (PSS-Li) are used to construct composite membranes for the protection of the Li-anode, which shows long-term operation over 1000 h in Li-Li sym. cells in the presence of redox chems. that accelerate the cathodic reaction. The high content of Li+ of PSS-Li can not only inhibit the dissolution and diffusion of redox mols. in the membrane, but also improve the Li+ transport rate through the membrane. In our study, we take a lithium-oxygen (Li-O2) battery as the model device and 2,2,6,6-tetramethyl-1-piperidinyloxy as the model redox chem. to accelerate the cathodic reaction. Compared with conventional membranes, artificial membranes can effectively inhibit the side reaction between the redox mols. and the lithium anode. Consequently, the energy efficiency and cycle stability (over three times) of Li-O2 batteries are greatly improved. This provides an important theor. basis and tech. support for the design and preparation of membranes for high performance energy-conversion batteries.

Hegemann, P. published the artcileStability of tetraglyme for reversible magnesium deposition from a magnesium aluminum chloride complex, Safety of 2,5,8,11,14-Pentaoxapentadecane, the main research area is stability tetraglyme reversible magnesium deposition aluminum chloride complex.

The electrochem. behavior of Mg deposition and stripping at Au-electrode in magnesium aluminum chloride complex (MACC) tetraglyme electrolyte was studied using differential electrochem. mass spectrometry (DEMS) and scanning tunneling microscopy (STM). During Mg deposition no dendrites are formed. MACC electrolyte supports reversible Mg deposition with high coulombic efficiency. Despite of the high coulombic efficiencies that was observed in MACC, appreciable ethylene formation due to the decomposition of tetraglyme was detected solely during Mg stripping. The mechanism of organic solvent decomposition will be discussed. This ethylene formation is quant. responsible for the missing charge balance of Mg-deposition and dissolution Possible origins will be discussed.

Tan, Tian published the artcilePrediction of infinite-dilution activity coefficients with neural collaborative filtering, HPLC of Formula: 143-24-8, the main research area is prediction infinite dilution activity coefficient neural collaborative filtering.

Accurate prediction of infinite dilution activity coefficient (γ∞) for phase equilibrium and process design is crucial. In this work, an exptl. γ∞ dataset containing 295 solutes and 407 solvents (21,048 points) is obtained through data integrating, cleaning, and filtering. The dataset is arranged as a sparse matrix with solutes and solvents as columns and rows, resp. Neural collaborative filtering (NCF), a modern matrix completion technique based on deep learning, is proposed to fully fill in the γ∞ matrix. Ten-fold cross-validation is performed on the collected dataset to test the effectiveness of the proposed NCF, proving that NCF outperforms the state-of-the-art phys. model and previous machine learning model. The completed γ∞ matrix makes solvent screening and extension of UNIFAC parameters possible. Taking two typical hard-to-sep. systems (benzene/cyclohexane and Me cyclopentane/n-hexane mixtures) as examples, the NCF-developed database provides high-throughput screening for separation systems in terms of solvent selectivity and capacity.

Xue, Hairong published the artcileHollow mesoporous Fe2O3 nanospindles/CNTs composite: an efficient catalyst for high-performance Li-O2 batteries, COA of Formula: C10H22O5, the main research area is iron oxide carbon nanotube composite hydrolysis; Li-O2 batteries; carbon support; cathodic catalyst; hollow mesoporous structure; transition metal oxides.

The design of mesoporous or hollow transition metal oxide/carbon hybrid catalysts is very important for rechargeable Li-O2 batteries. Here, spindle-like Fe2O3 with hollow mesoporous structure on CNTs backbones (Fe2O3-HMNS@CNT) are prepared by a facile hydrolysis process combined with low temperature calcination. Within this hybrid structure, the hollow interior and mesoporous shell of the Fe2O3 nanospindles provide high sp. surface area and abundant catalytical active sites, which is also beneficial to facilitating the electrolyte infiltration and oxygen diffusion. Furthermore, the crisscrossed CNTs form a three-dimensional (3D) conductive network to accelerate and stabilize the electron transport, which leads to the decreasing internal resistance of electrode. As a cathodic catalyst for Li-O2 batteries, the Fe2O3-HMNS@CNT composite exhibits high specific capacity and excellent cycling stability (more than 100 cycles).

Wang, Junbo published the artcileIn situ growth of Co3O4 on nitrogen-doped hollow carbon nanospheres as air electrode for lithium-air batteries, Name: 2,5,8,11,14-Pentaoxapentadecane, the main research area is inSitu growth cobalt oxide nitrogen doped hollow carbon nanosphere; air electrode lithium battery.

Design and synthesis of efficient bifunctional electrocatalysts for both O reduction reaction and O evolution reactions are of great significant for metal-air batteries. Here, bifunctional catalysts consisting of Co3O4 nanocrystals and N-doped hollow C nanospheres are synthesized through in situ growth of Co3O4 nanocrystals on the surface of N-doped hollow C nanospheres. The observed Co-N bond formation is an indication of the nucleation of Co3O4 nanocrystals starting from N-sites in N-doped hollow C nanospheres. The resulted hybrids exhibit improved activity towards O reduction reaction compared to pristine N-doped hollow C nanospheres in terms of the 42 mV pos. shift of half-wave potential and comparable activity towards O evolution reactions with com. RuO2 and IrO2 catalysts. The thus-assembled Li-O battery delivers an initial discharge capacity of 3325 mAh/g at 100 mA/g using mixed gas of O and Ar (20% of O in volume). The battery fails after 27 discharge/charge cycles due to the accumulation of discharge products on electrode.

Tripathi, Balram published the artcileBiFeO3 Coupled Polysulfide Trapping in C/S Composite Cathode Material for Li-S Batteries as Large Efficiency and High Rate Performance, Category: ethers-buliding-blocks, the main research area is carbon sulfur composite; bismuth iron oxide polysulfide composite cathode lithium sulfur battery.

We demonstrated the efficient coupling of BiFeO3 (BFO) ferroelec. material within the carbon-sulfur (C-S) composite cathode, where polysulfides are trapped in BFO mesh, reducing the polysulfide shuttle impact, and thus resulting in an improved cyclic performance and an increase in capacity in Li-S batteries. Here, the built-in internal field due to BFO enhances polysulfide trapping. The observation of a difference in the diffusion behavior of polysulfides in BFO-coupled composites suggests more efficient trapping in BFO-modified C-S electrodes compared to pristine C-S composite cathodes. The X-ray diffraction results of BFO-C-S composite cathodes show an orthorhombic structure, while Raman spectra substantiate efficient coupling of BFO in C-S composites, in agreement with SEM images, showing the interconnected network of submicron-size sulfur composites. Two plateaus were observed at 1.75 V and 2.1 V in the charge/discharge characteristics of BFO-C-S composite cathodes. The observed capacity of ∼1600 mAh g-1 in a 1.5-2.5 V operating window for BFO30-C10-S60 composite cathodes, and the high cyclic stability substantiate the superior performance of the designed cathode materials due to the efficient reduction in the polysulfide shuttle effect in these composite cathodes.

Huang, Kai published the artcileSystematic Optimization of High-Energy-Density Li-Se Semi-Solid Flow Battery, Safety of 2,5,8,11,14-Pentaoxapentadecane, the main research area is tetraethylene glycol dimethyl ether lithium selenium energy density optimization.

Redox flow batteries (RFBs) are still unable to be applied in more fields due to their low energy d. This work proposes a high-energy-d. Li-Se semi-solid flow battery (SSFB), and improves its performance through an optimization process. The effect of composite synthesis, current collector types, and electrolyte solvent types are systematically studied. The method of impregnating Se and Ketjen black (KB) directly according to their proportion in the suspension as a composite without adding addnl. KB can not only effectively improve the stability and utilization of suspension, but also greatly reduce its viscosity. Carbon paper is used as the current collector to improve the performance of the system by its smaller contact resistance. The selected solvent of tetraethylene glycol di-Me ether (TEGDME) has smaller volatility and a larger contact angle, which contributes to the formation of a stable and uniform suspension. After optimization, the demonstrated system has achieved a volumetric capacity of 156-386 Ah L-1 with high Coulombic efficiency (≈100%) for 100 cycles. Finally, the intermittent-flow mode test has confirmed the applicability of the system. This research provides a reference for the practical application of SSFBs and a direction for the optimization of other types of suspensions.

Kitaura, Hirokazu published the artcileAn ultrafast process for the fabrication of a Li metal-inorganic solid electrolyte interface, Application of 2,5,8,11,14-Pentaoxapentadecane, the main research area is lithium metal inorganic solid electrolyte fabrication ultrafast.

A lithium anode is expected to be applied to next-generation batteries using inorganic solid electrolytes (ISEs). When joining Li with ISEs, interfacial reactions often cause performance degradation and have been avoided. In this report, we demonstrate a new strategy for the ultrafast formation of a good interface between Li and ISEs, using a reactive process (ultrasonic-assisted fusion welding method). We found that ultrasonic irradiation helps in suitable interface formation between molten Li and ISEs, and the joining process finishes in just a few seconds. The obtained interface showed a low resistance and could be used under a high c.d. of 0.5 mA cm-2. The development of prototype cells for next-generation batteries was promoted by this ultrafast process.

Kucuk, Asuman Celik published the artcileInfluence of LiBOB as an electrolyte additive on the performance of BiF3/C for fluoride shuttle batteries, HPLC of Formula: 143-24-8, the main research area is bismuth fluoride carbon film battery electrolyte ionic conductivity.

The potential effects of using lithium bis(oxalato)borate (LiBOB) as an electrolyte additive on the redox reactions of the pos. bismuth fluoride (BiF3) electrode were investigated in tetraglyme (G4) containing the anion acceptor (AA) triphenylboroxin (TPhBX). The electrolyte system, containing 0.06 M LiBOB, 0.5 M TPhBX, and saturated cesium fluoride (CsF) was prepared The study also included a comparison with previously studied systems based on G4, which did not contain LiBOB but AA. The tolerances to reduction and oxidation were enhanced after introducing LiBOB to the system. The capacity of BiF3 improved at C/10 rate. Defluorination of BiF3 was demonstrated to proceed through a direct desorption-insertion mechanism, whereas the contribution of the dissolution-deposition mechanism was known to be predominant in the G4-based systems. Addition of only 1 weight/weight% LiBOB to the G4 system resulted in an interesting change in the mechanism and an improvement in the capacity at high C rate. This improvement was associated with the increasing electrochem. stability of the electrolyte due to the interaction between BOB- and Cs+, reducing the possibilities of electrolyte degradation and loss of active material owing to a direct desorption-insertion mechanism.

Cao, Deqing published the artcileOxidative decomposition mechanisms of lithium carbonate on carbon substrates in lithium battery chemistries, SDS of cas: 143-24-8, the main research area is oxidative decomposition lithium carbonate carbon battery.

Lithium carbonate plays a critical role in both lithium-carbon dioxide and lithium-air batteries as the main discharge product and a product of side reactions, resp. Understanding the decomposition of lithium carbonate during electrochem. oxidation (during battery charging) is key for improving both chemistries, but the decomposition mechanisms and the role of the carbon substrate remain under debate. Here, we use an in-situ differential electrochem. mass spectrometry-gas chromatog. coupling system to quantify the gas evolution during the electrochem. oxidation of lithium carbonate on carbon substrates. Our results show that lithium carbonate decomposes to carbon dioxide and singlet oxygen mainly via an electrochem. process instead of via a chem. process in an electrolyte of lithium bis(trifluoromethanesulfonyl)imide in tetraglyme. Singlet oxygen attacks the carbon substrate and electrolyte to form both carbon dioxide and carbon monoxide-approx. 20% of the net gas evolved originates from these side reactions. Addnl., we show that cobalt(II,III) oxide, a typical oxygen evolution catalyst, stabilizes the precursor of singlet oxygen, thus inhibiting the formation of singlet oxygen and consequent side reactions.
