Resumo:

The tetrel bond (TB) between 1,2-benzisothiazol-3-one-2-TF3-1,1-dioxide (T = C, Si) and the O atom of pyridine-1-oxide (PO) and its derivatives (PO-X, X = H, NO2, CN, F, CH3, OH, OCH3, NH2, and Li) is examined by quantum chemical means. The Si∙∙∙O TB is quite strong, with interaction energies approaching a maximum of nearly 70 kcal/mol, while the C∙∙∙O TB is an order of magnitude weaker, with interaction energies between 2.0 and 2.6 kcal/mol. An electron-withdrawing substituent on the Lewis base weakens this TB, while an electron-donating group has the opposite effect. The SiF3 group transfers roughly halfway between the N of the acid and the O of the base without the aid of cooperative effects from a third entity.

Resumo:

The behavior of individual Na channels in the apical membrane of the rat cortical collecting tubule (CCT) was studied at different concentrations of the permeant ions Na and Li. Tubules were opened to expose their luminal surfaces and bathed in K-gluconate medium to minimize tubule-to-tubule variation in cell membrane potential and intracellular Na concentration. The patch-clamp technique was used to resolve currents through individual channels. The patch-clamp pipette was filled with solutions containing variable concentrations of either NaCl or LiCl. In one series of experiments, the concentrations were changed without substitutions. In another series, the ionic strength and Cl concentration were maintained constant by partial substitution of Li with N-methyl-D-glucamine (NMDG). In cell-attached patches, both the single-channel conductance (g) and the single-channel current (i) saturated as functions of the Na or Li activity in the pipette. Without NMDG, the saturation of i was well described by Michaelis-Menten kinetics with an apparent Km of approximately 20 mM activity for Na and approximately 50 mM activity for Li. Km was independent of voltage for both ions. With substitution for Li by NMDG, the apparent Km value for Li transport through the channels increased. The values of the probability of a channel's being open (Po) varied from patch to patch, but no effect of pipette ion activity on Po could be demonstrated. A weak dependence of Po on membrane voltage was observed, with hyperpolarization increasing Po by an average of 2.3%/mV.

Resumo:

Silicon-carbon nanocomposite materials are widely adopted in the anode of lithium-ion batteries (LIB). However, the lithium ion (Li+) transportation is hampered due to the significant accumulation of silicon nanoparticles (Si) and the change in their volume, which leads to decreased battery performance. In an attempt to optimize the electrode structure, we report on a self-assembly synthesis of silicon nanoparticles@nitrogen-doped reduced graphene oxide/carbon nanofiber (Si@N-doped rGO/CNF) composites as potential high-performance anodes for LIB through electrostatic attraction. A large number of vacancies or defects on the graphite plane are generated by N atoms, thus providing transmission channels for Li+ and improving the conductivity of the electrode. CNF can maintain the stability of the electrode structure and prevent Si from falling off the electrode. The three-dimensional composite structure of Si, N-doped rGO, and CNF can effectively buffer the volume changes of Si, form a stable solid electrolyte interface (SEI), and shorten the transmission distance of Li+ and the electrons, while also providing high conductivity and mechanical stability to the electrode. The Si@N-doped rGO/CNF electrode outperforms the Si@N-doped rGO and Si/rGO/CNF electrodes in cycle performance and rate capability, with a reversible specific capacity reaching 1276.8 mAh/g after 100 cycles and a Coulomb efficiency of 99%.

Mixing graphite with Si particles in anodes of Li-ion batteries provides increased specific energy. In addition, higher Si contents lead to thinner anode coatings at constant areal capacity. In the present study, we systematically investigated the influence of the Si content on the susceptibility of Li plating on Si/graphite anodes. Si/graphite anodes with Si contents from 0 to 20.8 wt% combined with NMC622 cathodes were manufactured on pilot-scale. After initial characterization in coin half cells and by SEM, pouch full cells with fixed N/P ratios were built. Rate capability at different temperatures, and Post-Mortem analysis were carried out. Results from voltage relaxation, Li stripping, SEM measurements, glow discharge optical emission spectroscopy (GD-OES) depth profiling, and optical microscopy were validated against each other. A decreasing susceptibility to Li plating with increasing Si content in the anodes could be clearly observed. A critical C-rate was defined, at which Li plating was detected for the first time. It was also found that at 0 °C the critical C-rate increases with increasing Si contents. At 23 °C the SOC at which Li dendrites were first observed on the anode also increased with higher Si content.

The electronic structure of the epitaxial GaN/Si(111) layers and the Li/GaN/Si(111) interface with a monolayer Li coverages has been studied in situ under ultrahigh vacuum conditions. The experiments were carried out using photoelectron spectroscopy with synchrotron radiation in the photon energy range 75 eV – 850 eV. The photoemission spectra in the valence band and the core levels of Ga 3d, N 1s, and Li 1s are studied for the monolayer Li coating. It is found that Li adsorption causes a significant decrease in the intensity of the photoemission line of the intrinsic surface state and the appearance of an induced surface state due to charge transfer between the adsorbed Li layer and surface Ga atoms. It has been found that the GaN/Si(111) surface has predominantly Ga polarity. The Li/GaN/Si(111) interface has a semiconductor character.

Resumo:

Enabling silicon as an anode material for LIBs has been largely impeded by the severe volume changes it undergoes during cell operation, causing continuous Li inventory loss . Therefore, It is important to understand and quantify various sources of capacity fade in order to design effective mitigation strategies. In this work, we used a method based on Titration Gas Chromatography (TGC) to show a non-linear volume expansion in µSi anode during the electrochemical lithiation process. The severe volume expansion towards the end of lithiation leads to the accelerated SEI formation and thus leading to the conductive pathway loss, which results in a large amount of trapped Li-Si alloy accumulation. This TGC method was also applied to study μSi anodes with two different binders namely: Sodium Carboxymethyl Cellulose (CMC-Na) and Polyacrylic Acid (PAA). The main reason for capacity loss for the anode with CMC-Na binder was the trapped Li-Si alloy, which was reduced by using a more mechanically robust PAA binder. The concept of State of Charge (SoC) control was also investigated in µSi-LFP full cells with both the binders by tuning the N/P ratios from 1.5 to 3. The results showed that binder robustness is important for mitigating the trapped Li-Si alloy accumulation in µSi anode. Additionally, the effect of particle size of active material on trapped Li-Si accumulation was also investigated using the TGC method Figure: Cycle performance of µSi- CMC-Na-LFP full-cell with various N/P ratios (b) Cycle performance of µSi-PAA-LFP full-cell with various N/P ratios (c) TGC Data for Lithium inventory loss of full cell after 1st cycle for various N/P ratios (d) TGC Data for Lithium inventory loss of full cell after 10 cycles for various N/P ratios Figure 1

Resumo:

Commercially, Si nanoparticles (nano Si) are blended with graphite to construct high-capacity Si/C anodes. However, this strategy falls short because of the high cost of nano Si, serious pollution due to the use of organic solvent, and weak physical-electrical connection between graphite and Si. Herein, using low-cost micron-sized Si (μSi) and graphite as the raw materials, we proposed a facial ball-milling method to construct high-performance Si/C anode (μSi/C@CH) in which milled Si particles are protected both by graphite matrix and homogeneous chitosan-derived carbon layer. It is shown that the N and O atoms not only tend to coordinate with Li+, generating uniformly-distributed Li+ transport channels, but also improve the electrical conductivity of the anode materials. As a result, μSi/C@CH shows high cycling stability (376.7 mAh g-1 at 0.5 A g-1 after 500 cycles) and good rate capability of 120.2 mAh g-1 at 5 A g-1. This dual protection strategy facilitates the practical application of Si/C materials in high-energy density Li ion batteries (LIBs).

Resumo:

The formation of a halogen-bonded network using four NHX-(CH2)3-NX-(CH2)3-NHX molecules (X = Cl, Br, or I) is investigated using DFT. The self-assembly of the four basic motifs results in a tube-like structure with C4h symmetry, with one halogen-bonded network located at each end of the structure and one at its center. Each halogen-bonded network has four quasi-planar N-X···N interactions with binding energies that increase with the size of X. The structure is found to bind Li+ at each of the halogen-bonded networks, albeit more strongly at its center. The binding of Li+ is driven by halogen atom lone pairs that produce a rich electron density orthogonal to the halogen bond. The presence and strength of the interactions are further examined using AIM and NBO calculations. Lastly, IRC calculations are performed to examine the transitions between the Li+ complex minima and, thus, the potential for transporting the metal ion from one end of the tube to the other. Based on the tetrameric structure, a model intramolecular structure is built and considered as a potential host for Li+. In this case, the central intermolecular N-X···N network is replaced by an intramolecular Si-C≡C-Si network. Interestingly, both intermolecular and intramolecular structures exhibit similar Li+ binding abilities.

Resumo:

In this paper, we described a method of double-sided diffusion and drift of lithium-ions into monocrystalline silicon for the formation of the large-sized, p-i-n structured Si(Li) radiation detectors. The p-i-n structure is a p-n junction with a doped region, where the “i-region” is between the n and the p layers. A well-defined i-region is usually associated with p or n layers with high resistivities. The p-i-n structure is mostly used in diodes and in some types of semiconductor radiation detectors. The uniqueness of this method is that, in this method, the processes of diffusion and drift of lithium-ions, which are the main processes in the formation of Si(Li) p-i-n structures, are produced from both flat sides of cylindrical-shaped monocrystalline silicon, at optimal temperature (T = 420 °C) conditions of diffusion, and subsequently, with synchronous supply of temperature (from 55 to 100 °C) and reverse bias voltage (from 70 to 300 V) during drift of lithium-ions into silicon. Thus, shortening the manufacturing time of the detector and providing a more uniform distribution of lithium-ions in the crystal volume. Since, at present, the development of manufacturing of large-sized Si(Li) detectors is hindered due to difficulties in obtaining a uniformly compensated large area and time-consuming manufacturing process, the proposed method may open up new possibilities in detector manufacturing.

The results of experimental studies of the electronic and photoemission properties of an epitaxial GaN layer grown on a SiC/Si(111) substrate by plasma assisted molecular beam epitaxy are presented. The electronic structure of the GaN surface and ultrathin Li/GaN interface was first studied in situ under ultrahigh vacuum conditions under different Li coverages. The experiments were performed using photoelectron spectroscopy with synchrotron radiation in the photon energy range of 75–850 eV. The photoemission spectra in the region of the valence band and surface states and the photoemission spectra from the N 1s, Ga 3d, Li 2s core levels were studied for different submonolayer Li coverages. It is established that Li adsorption causes significant changes in the general form of the spectra induced by charge transfer between the Li layer and the lower N and Ga layers. It is established that the GaN surface has predominantly N-polarity. The semiconductor character of the Li / GaN interface is shown.

All-solid-state lithium-ion batteries (ASSLBs) have garnered considerable attention as the next-generation electrochemical energy storage systems due to their high chemical safety and wide electrochemical potential windows1. Among the available candidates for ASSLB negative electrodes, silicon is a promising material because of its extremely high theoretical capacity and low lithiation/delithiation potential2. However, Si is known to undergo severe structural changes during electrochemical lithiation/delithiation, as revealed by our previous operando studies using a laboratory-based X-ray photoelectron spectroscopy setup3,4. These dramatic structural changes may result in a significant volume expansion/contraction, leading to particle cracking, pulverization, and electrode failure. Hence, the understanding and control of such physicochemical phenomena are critical to prevent nanomechanical and electrochemical degradation of the electrode. In this talk, we will introduce our newly developed operando bimodal atomic force microscopy (AFM) system which enables real-time nanomechanical monitoring of an amorphous Si thin film electrode during electrochemical lithiation/delithiation, simultaneously with cross-sectional topography imaging5. An ASSLB cell composed of 3 µm-thick Si thin film/500 µm-thick Li6.6La3Zr1.6Ta0.4O12 (LLZT) solid electrolyte/50 µm-thick Li foil (Si/LLZT/Li) was fabricated, and its cross-section was smoothened by an Ar-ion beam prior to carrying out the nanomechanical mapping on the Si/LLZT interface. The nanomechanical mapping was performed during the first electrochemical lithiation and delithiation within a potential window of 0.01-1.20 V vs. Li+/Li under Ar atmosphere (H2O < 0.1 ppm, O2 < 0.1 ppm). Nanomechanical property maps of the Si electrode, in the form of Young’s modulus maps, were successfully acquired as a function of apparent Li content x in lithium silicide (Li x Si), together with real-time topography images. At the first lithiation, the average Young’s modulus drastically decreased due to the formation of Li x Si from pristine Si, followed by a moderate modulus reduction up to a capacity of 3300 mAh g-1 (x = 3.46 in Li x Si). Throughout the successive delithiation up to 1467 mAh g-1 (x = 1.54 in Li x Si), the average modulus was gradually recovered. The Li x Si moduli obtained from this study are consistent with the values from the first-principles calculations, showing the sensitivity and reliability of the technique6. The demonstrated technique can be implemented for a wide range of battery materials for both solid-state and liquid-electrolyte lithium battery systems. References: K. Takada. J.

Semiconductor p-i-n structure with long i-base region doped with shallow donors/acceptors can be successfully used and have significant advantages in millimeter wave range as cooling THz receivers. It is shown that such detectors working in double current injection mode can have high current photosensitivity and detectivity, linear dependencies of sensitivity versus wavelength and applied voltage. Simulation results can be successfully used for detectors fabricated on the basis of several semiconductors: Si : Li , Si : O , Ge : B , Ge : Al , Ge : Ti , Ge : Be , Ge : P , Ge : As , Ge : Sb , GaAs : Li , GaAs : Zn , GaAs : Cd , GaAs : X , GaP : N , which covered wavelengths 40–200 μm. The simulation results made in this paper have demonstrated the ability of double injection structures to perform as practical and sensitive power detectors for THz radiation.

Resumo:

The effects of excessive prelithiation on the full-cell performance of Li-ion batteries (LIBs) with a hard-carbon/nanosized-Si (HC/N-Si) composite anode were investigated; HC and N-Si simply mixed at mass ratios of 9:1 and 8:2 were analyzed. CR2032-type half- and full-cells were assembled to evaluate the electrochemical LIB anode behavior. The galvanostatic measurements of half-cell configurations revealed that the composite anode with an 8:2 HC/N-Si mass ratio exhibited a high capacity (531 mAh g−1) at 0.1 C and superior current-rate dependence (rate performance) at 0.1–10 C. To evaluate the practical LIB anode performance, the optimally performing composite anode was used in the full cell. Prior to full-cell assembly, the composite anodes were prelithiated via electrochemical Li doping at different cutoff anodic specific capacities (200–600 mAh g−1). The composite anode was paired with a LiNi0.5Co0.2Mn0.3O2 cathode to construct full-cells, the performance of which was evaluated by conducting sequential rate and cycling performance tests. Prelithiation affected only the cycling performance, without affecting the rate performance. Excellent capacity retention was observed in the full-cells with prelithiation conducted at cutoff anodic specific capacities greater than or equal to 500 mAh g−1.

Calendar aging of Li-ion batteries with Si/graphite electrodes was investigated within this study. A total of 121 single-layer pouch full cells with either graphite or Si/graphite (3.0 wt−%, 5.8 wt−% and 20.8 wt−% Si) anodes and NMC622 cathodes with the same N/P ratio were built on pilot-scale. Calendar aging was studied at SoC 30%, 60%, and 100%, as well as temperature (25 °C, 45 °C, 60 °C) and time dependence. The aging data was analyzed in terms of capacity fade and a square-root behavior was observed. Differential voltage analysis (DVA) has been performed as a function of aging time. The observed temperature and time dependence is best described by time dependent, 3D Arrhenius plots. Post-Mortem analysis (SEM, EDX, GD-OES) is applied to investigate the changes on electrode and material level. Conclusions are drawn on the main aging mechanisms for calendar aging of Li-ion cells with Si/graphite anodes and differences between Si/graphite and pure graphite anodes are discussed. The Si-containing cells show a combination of lithium inventory loss and a loss of accessible Si active material, both caused by SEI growth.

AbstractThe under reflux conditions in n-octane stable lithium hydridosilylamides Me2(H)Si-N(Li)R (1: R = CMe3, 2: SiMe3) were allowed to react with chlorotrimethylstannane and chloromethylsilanes Me4-nSiCln (n = 1 - 3) in different molar ratios. 1 reacts with Me3SnCl in n-pentane to give the cyclodisilazane [Me2Si-NCMe3]2 (3) and Me3SnH. The reaction of 2 with Me3SnCl under the same conditions leads to a mixture of Me2 (H)Si-N(SnMe3)SiMe3 (5), [Me2Si-NSiMe3]2 (4), and to Me3SnH. In the reactions of 1 and 2 with chlorotrimethylstannane in tetrahydrofuran the corresponding N-stannylation products Me2(H)Si-N(SnMe3)R 5, 6 and very small amounts of (Me3Sn)2 are formed. The results of the reactions of 1 and 2 with Me2SiCl2 and of 1 with MeSiCl3 in n-hexane show that hydrogen-chlorine-exchange proceeds between the reactants. With Me2SiCl2 the corresponding cyclodisilazanes [Me2Si-NR]2 3, 4, N-silylation products Me2(H)Si-N(SiMe2Cl)R 7b, 8b, and Me2(H)Si-N(SiMe2H)R 7c, 8c, and the silanes Me2SiHCl and Me2SiH2 are formed, the cyclodisilazanes being the main products. 1 and MeSiCl3 produce 3, Me2(H)Si-N(R′)CMe3 (7d: R′ = SiMeCl2, 7e: R' = SiMeCIH, 7f: R′ = SiM eH2) and MeSiH3. In comparison with the reaction of 1 with Me2SiCl2 the yield of cyclodisilazane is smaller and that of N-silylated compounds is higher. The reaction behaviour of 1 towards Me2SiCl2 and MeSiCl3 in THF is comparable to that in n-hexane. No silanimine intermediates are observed in the reactions of 1 or 2 with the chloromethylsilanes Me4-nSiCln (n = 1 - 3) in the molar ratios 1:5 and 1:10.
