Merrill, Laura C. published the artcilePolymer-Ceramic Composite Electrolytes for Lithium Batteries: A Comparison between the Single-Ion-Conducting Polymer Matrix and Its Counterpart, Application of 2,5,8,11,14-Pentaoxapentadecane, the main research area is polymer ceramic composite single ion conducting electrolyte lithium battery.

Single-ion-conducting polymer electrolytes are attractive to use in lithium batteries as the transference number of the lithium cation approaches unity. This helps prevent concentration gradients across the electrolyte, which can result in dendrite formation. The addition of ceramic particles to polymer electrolytes at high loadings can increase the mech. strength of the polymer, which can also help suppress dendrite formation. Here, a single-ion-conducting polymer electrolyte is blended with lithium-conducting oxide ceramic particles to make a composite electrolyte. This electrolyte is studied in comparison to a composite electrolyte containing freely dissolved lithium salt. It is found that the addition of ceramic particles to the single-ion-conducting polymer can result in increased cation dissociation and consequent increased ionic conductivity The electrolytes are cycled in lithium sym. cells, and it is found that the ceramic-containing electrolytes show increased interfacial stability with the lithium metal compared to the pristine polymer electrolytes. Our findings shed light on how to optimize the polymer host chem. to form composite electrolytes that can meet the challenging requirements to stabilize the lithium metal anode.

Semlali, Sanaa published the artcileEffect of solvent on silicon nanoparticle formation and size: a mechanistic study, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is silicon nanoparticle formation size solvent effect.

Silicon has emerged as the most desirable material for optical dielec. metamaterials, however chemists struggle to obtain the required silicon nanoparticle dimensions. Here the average diameter of silicon nanoparticles is varied between 3 and 15 nm by changing the reaction solvent. Electrochem. and NMR elucidate the role of solvent on the synthetic mechanism. Surprisingly the solvent does not stabilize the nanoparticles and there is no trend associated with chain length or open-chain vs. cyclical solvent mols. The solvent’s main role is to stabilize the byproducts, which prolongs the reaction lifetime.

Li, Ming-Shuang published the artcileCucurbit[n]urils (n = 7, 8) can strongly bind neutral hydrophilic molecules in water, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is cucurbituril crown ether dioxane inclusion reaction kinetics hydrogen bond.

It is challenging to recognize neutral hydrophilic mols. in water. Effective use of hydrogen bonds in water is generally accepted to be the key to success. In contrast, hydrophobic cavity is usually considered to play an insignificant role or only to provide a nonpolar microenvironment for hydrogen bonds. Herein, we report that hydrophobic cavity alone can also strongly bind neutral, highly hydrophilic mols. in water. We found that cucurbit[n]urils (n = 7, 8) bind 1,4-dioxane, crown ethers and monosaccharides in water with remarkable affinities. The best binding constant reaches 107 M-1 for cucurbit[8]uril, which is higher than its binding affinities to common organic cations. D. functional theory (DFT) calculations and control experiments reveal that the hydrophobic effect is the major contributor to the binding through releasing the cavity water and/or properly occupying the weakly hydrated cavity. However, hydrophobic cavity still prefers nonpolar guests over polar guests with similar size and shape.

Potangale, Mangesh published the artcileCorrelation of the empirical polarity parameters of solvate ionic liquids (SILs) with molecular structure, Related Products of ethers-buliding-blocks, the main research area is solvate ionic liquid mol structure empirical polarity parameter.

Empirical polarity parameters for 10 solvate ionic liquids (SILs) have been determined using Catalans probes. The solvation environment surrounding the probe mols. in the SILs is dependent on the mutual interactions between the cation, anion and chelating ligand, leading to characteristic values of the polarity parameters. The acidity of the SILs is comparable to the acidity of polar protic solvents, which is attributed to the ability of the Li cation to interact with the probe in a manner similar to H-bond donor. The choice of anion influenced the measured acidity of SILs by determining the extent of cation-probe interactions possible. The basicity showed a strong correlation with the nature of the anion but was also influenced by the extent of cation-anion interaction and choice of ligand. Temperature dependence of polarity parameters in SILs is relatively small, but shows some interesting trends.

Lee, Dawoon published the artcileHighly Flexible and Stable Solid-State Supercapacitors Based on a Homogeneous Thin Ion Gel Polymer Electrolyte Using a Poly(dimethylsiloxane) Stamp, Formula: C10H22O5, the main research area is flexible supercapacitor ion gel polymer electrolyte methylsiloxane stamp; ion gel polymer electrolyte (IGPE); metal−insulator−metal (MIM) capacitor; silicone-based elastomer; stamping method; supercapacitor.

To achieve both high structural integrity and excellent ion transport, designing ion gel polymer electrolytes (IGPEs) composed of an ionic conducting phase and a mech. supporting polymer matrix is one of the promising material strategies for the development of next-generation all-solid-state energy storage systems. Herein, an IGPE thin film is prepared, in which an ion-diffusing phase containing ionic liquids and lithium salts was bicontinuously intertwined with a cross-linked epoxy phase, using a silicon elastomer-based stamping method, thus producing a homogeneous IGPE-based thin film with low surface roughness = 0.5 nm. Following the optimization of the IGPE thin film in terms of the concentrations of ionic constituents, the film thickness, and various process parameters, the IGPE itself showed a high ionic conductivity of 0.23 mS/cm with a low activation energy for lithium-ion transport, as well as the high capacitance of approx. 10μF/cm2 based on the metal-insulator-metal configuration. Furthermore, an all-solid-state supercapacitor containing two IGPE coating-activated carbon electrodes produced using the poly(dimethylsiloxane) (PDMS) stamping method exhibited high energy and power densities (44 W h/kg at 875 W/kg and 28 kW/kg at 3 W h/kg). It was also found that this supercapacitor showed a dramatic reduction (> 50%) of the current-resistance (IR) drop, which is an indicator of low interface resistance, while maintaining the initial electrochem. performance even after severe mech. deformation such as bending or rolling. Therefore, all these results support the fact that our developed PDMS stamping method enables the rendering of a high-performance ion gel polymer thin-film-based electrolyte with acceptable stability and mech. flexibility for all-solid-state wearable energy storage devices.

Jabbari, Vahid published the artcileA Smart Lithium Battery with Shape Memory Function, Category: ethers-buliding-blocks, the main research area is lithium battery shape memory polymer ionic conductivity mech deformation; flexible electronics; mechanical deformation; shape memory polymer electrolytes; shape recovery; shape-adjustable batteries.

Rapidly growing flexible and wearable electronics highly demand the development of flexible energy storage devices. Yet, these devices are susceptible to extreme, repeated mech. deformations under working circumstances. Herein, the design and fabrication of a smart, flexible Li-ion battery with shape memory function, which has the ability to restore its shape against severe mech. deformations, bending, twisting, rolling or elongation, is reported. The shape memory function is induced by the integration of a shape-adjustable solid polymer electrolyte. This Li-ion battery delivers a specific discharge capacity of ≈140 mAh g-1 at 0.2 C charge/discharge rate with ≈92% capacity retention after 100 cycles and ≈99.85% Coulombic efficiency, at 20°C. Besides recovery from mech. deformations, it is visually demonstrated that the shape of this smart battery can be programmed to adjust itself in response to an internal/external heat stimulus for task-specific and advanced applications. Considering the vast range of available shape memory polymers with tunable chem., phys., and mech. characteristics, this study offers a promising approach for engineering smart batteries responsive to unfavorable internal or external stimulus, with potential to have a broad impact on other energy storage technologies in different sizes and shapes.

Zhao, Bowen published the artcileInsoluble Naphthoquinone-Derived Molecular Cathode for High-Performance Lithium Organic Battery, Computed Properties of 143-24-8, the main research area is insoluble naphthoquinone mol cathode lithium organic battery.

Organic electrode materials have attracted significant attention for rechargeable lithium organic batteries owing to the anticipated electrochem. property and environmentally friendly features. Benzoquinone and naphthoquinone as the simplest quinone substances have been considered as promising cathode materials because of their high theor. specific capacities and discharge voltages. However, they are soluble in most organic liquid electrolytes, which results in poor electrochem. performance. Herein, a novel mol. cathode material based on naphthoquinone, i.e., 2,2�(1,4-phenylenedithio) bis(1,4-naphthoquinone) (1,4-PNQ), is designed and synthesized. It shows greatly decreased solubility as a result of strong intermol. interactions. In a lithium half cell, it exhibits high carbonyl utilization of close to 100% with a high initial capacity of 231 mAh g-1. Meanwhile, 1,4-PNQ presents improved cyclability, retaining a high capacity of 185 mAh g-1 after 120 cycles. Remarkably, it retains 93.5% of the initial capacity after 500 cycles at 5 C rate. This work provides a novel mol. design strategy to develop naphthoquinone-derived cathode materials for high performance lithium organic batteries.

Zhao, Huimin published the artcileRu nanosheet catalyst supported by three-dimensional nickel foam as a binder-free cathode for Li-CO2 batteries, Synthetic Route of 143-24-8, the main research area is ruthenium catalyst nickel foam lithium carbon dioxide battery cathode.

Due to the capability of CO2 uptake and the high theor. energy d., Li-CO2 batteries have attracted a great deal of attention as a novel and promising energy storage system which is based on the reversible reaction between lithium and CO2. However, the insulating Li2CO3 formed upon the discharge process, which is difficult to be decomposed during recharge process due to the lack of effective cathode catalyst, leads to the poor cycling performance and huge overpotential of the Li-CO2 batteries. In this work, the Ru nanosheets were directly grown on one side of the three-dimensional nickel foam through a galvanic replacement reaction to form the Ru/Ni electrode, which was further used in the Li-CO2 batteries. The highly dispersed Ru nanosheets in the Ru/Ni cathode effectively promote the decomposition of discharge product Li2CO3 and thus reduce the charge overpotential. Moreover, the typical porous and binder-free Ru/Ni electrode not only has a sturdy construction to suppress the side reaction in the Li-CO2 batteries, but also enables the rapid permeation of CO2 and electrolyte/electron into the active sites of the Ru/Ni electrode. As a result, the Ru/Ni cathode-based Li-CO2 battery exhibits the superior discharge capacity (9502 mAh g-1), good coulombic efficiency (95.4%) and excellent rate performance (3177 mAh g-1 at 500 mA g-1) at the full discharge/charge condition. When operated at the limited capacity of 1000 mAh g-1, this cell can run for over 100 cycles with the charge potential below 4.1 V. The findings provide a snapshot towards improving the reversibility of Li-CO2 batteries by designing the binder-free stable cathodes.
