The article was titled 《Impact of 3-Cyanopropionic Acid Methyl Ester on the Electrochemical Performance of ZnMn2O4 as Negative Electrode for Li-Ion Batteries》, and you may find the article in Energy Technology (Weinheim, Germany).Category: esters-buliding-blocks The information in the text is summarized as follows:

Due to their high theor. capacity, transition metal oxide compounds are promising electrode materials for lithium-ion batteries. However, one drawback is associated with relevant capacity fluctuations during cycling, widely observed in the literature. Such strong capacity variation can result in practical problems when pos. and neg. electrode materials have to be matched in a full cell. Herein, the study of ZnMn2O4 (ZMO) in a nonconventional electrolyte based on 3-cyanopropionic acid Me ester (CPAME) solvent and LiPF6 salt is reported for the first time. Although ZMO in LiPF6/CPAME electrolyte displays a dramatic capacity decay during the first cycles, it shows promising cycling ability and a suppressed capacity fluctuation when vinylene carbonate (VC) is used as an additive to the CPAME-based electrolyte. To understand the nature of the solid electrolyte interphase (SEI), the electrochem. study is correlated to ex situ XPS. In the experiment, the researchers used Vinylene carbonate(cas: 872-36-6Category: esters-buliding-blocks)

Recommanded Product: 872-36-6In 2021 ,《High Energy Density and Stable Three-Dimensionally Structured Se-Loaded Bicontinuous Porous Carbon Battery Electrodes》 was published in Energy Technology (Weinheim, Germany). The article was written by Wang, Junjie; Qu, Subing; Zhang, Runyu; Yang, Ke; Zhang, Shiyan; Nuzzo, Ralph G.; Nanda, Jagjit; Braun, Paul V.. The article contains the following contents:

3D-structured Se-loaded bicontinuous porous carbon (BPC) electrodes are fabricated through colloidal templating of BPC followed by pulsed-voltage Se electrodeposition. The resultant electrodes are found to deliver a specific capacity of 665 mAh g-1 at a rate of 0.1 C, near the theor. value for Se. When a vinylene carbonate (VC) containing electrolyte is utilized, the capacity fade over 500 cycles at 1 C rate is as small as a few percent. Impedance measurements and phys. characterization of cycled electrodes indicate the exceptionally stable cycling performance is possibly due to VC resulting in the formation of a stable solid electrolyte interface (SEI) during cycling. Along with the cycling stability, the rate performance of the 3D Se/BPC electrodes is also good. Due to the bicontinuous structure of carbonaceous current collector at rates as high as 5 C, the deliverable capacity is about 300 mAh g-1.

《A study of vinylene carbonate and prop-1-ene-1,3 sultone electrolyte additives using polycrystalline Li[Ni0.6Mn0.2Co0.2]O2 in positive/positive symmetric cells》 was written by Liu, Yulong; Hamam, Ines; Dahn, J. R.. Recommanded Product: Vinylene carbonateThis research focused onvinylene carbonate lithium nickel manganese cobalt oxygen sym cell. The article conveys some information:

Vinylene carbonate (VC) and prop-1-ene-1,3 sultone (PES) have been reported to have beneficial effects on both neg. and pos. electrodes of Li-ion cells. To simplify evaluation of these two additives with Li[Ni0.6Mn0.2Co0.2]O2 (NMC622), pos./ pos. sym. cells were used to exclude the influence from any neg. electrode. The compatibility of electrolytes containing 2%VC or 2%PES with NMC622 in 1M LiPF6 EC:DEC (volume/volume 1:2) electrolyte was evaluated by multiple voltage hold periods at 55°C to accelerate the capacity fade. EIS spectra showed 2%PES is superior for impedance control compared to 2%VC. dV/dQ vs V fitting results showed that active mass loss is worse at high voltage than low voltage regardless of electrolyte used. Cross-sectional SEM images showed more microcracking of NMC622 particles at high voltage than at low voltage, which was more severe at the end of testing than at the beginning of testing. Sym. cell storage at 0 V (ca. 3.8 V vs Li/Li+) and 0°C showed a significant increase in cell impedance for cells stored after the end of testing and a moderate impedance increase for cells stored at the beginning of testing suggesting the accumulation of deleterious reaction products in the cells during testing.

《Exploring the Role of Vinylene Carbonate in the Passivation and Capacity Retention of Cu2Sb Thin Film Anodes》 was written by Kraynak, Leslie A.; Schneider, Jacob D.; Prieto, Amy L.. Reference of Vinylene carbonateThis research focused onvinylene carbonate copper antimonide anode passivation capacity retention; lithium ion battery electrode vinylene carbonate passivation capacity retention. The article conveys some information:

Electrolyte additives such as vinylene carbonate (VC) have been demonstrated to improve the capacity retention for many types of Li-ion battery electrodes, including intermetallic alloying anodes, but it is still unclear why VC extends the cycle lifetime of copper antimonide (Cu2Sb) anodes so dramatically. Here, we have studied how VC affects the solid electrolyte interface formed on Cu2Sb thin film anodes in fluorine-free electrolyte solutions in order to better understand which nonfluorinated species may play an important role in effective Cu2Sb passivation. Using differential capacity anal. and XPS, it was found that VC effectively passivates Cu2Sb and prevents Cu/Cu2Sb oxidation at high potentials. Carbonate species from the reduction of VC seem to play an important role in passivation, while inorganic species like LiClO4 from the F-free supporting electrolyte do not seem to be beneficial. In addition to this study using Vinylene carbonate, there are many other studies that have used Vinylene carbonate(cas: 872-36-6Reference of Vinylene carbonate) was used in this study.

And the article was published in Journal of the Electrochemical Society in 2019. Quality Control of Vinylene carbonate The author mentioned the following in the article:

Here, the electrochem. performance of directly grown Ge nanowire anodes in full-cell Li-ion configurations (LiCoO cathodes) are examined The impacts of voltage window, anode/cathode balancing and anode preconditioning are assessed. The cells had a usable upper cutoff of 3.9 V, with a higher voltage cutoff of 4.2 V shown by SEM anal. to lead to Li plating on the anode surface. The rate performance of Ge NW anodes was shown to be boosted within full-cells compared to half-cells, meaning that existing studies may underestimate the rate performance of alloying mode anode materials if they are only based on half-cell studies. The capacity retention of the full-cells is lower compared to equivalent half-cells due to progressive consumption of cycleable Li. This phenomenon is demonstrated using a parallel anode and cathode delithiation approach that could be extended to other full-cell systems. The findings stress the importance of testing promising anode materials within full-cell configurations, to identify specific capacity fade mechanisms that are not relevant to half-cells and aid the development of higher energy d. storage systems.

The author of 《Temperature dependent EIS studies separating charge transfer impedance from contact impedance in lithium-ion symmetric cells》 were Keefe, A. S.; Buteau, Samuel; Hill, I. G.; Dahn, J. R.. And the article was published in Journal of the Electrochemical Society in 2019. Electric Literature of C3H2O3 The author mentioned the following in the article:

Measuring electrochem. impedance spectra of lithium-ion sym. cells at low temperatures allows for unambiguous separation of charge transfer impedance contributions from other cell impedance features. Electrodes from dry Li[Ni0.5Mn0.3Co0.2]O2 (NMC 532)/artificial graphite (AG) pouch cells were used to make blocking electrode configuration sym. cells and blocking electrode full coin cells. NMC532/AG cells with 1.2M LiPF6 in EC:DMC 3:7 (w:w) electrolyte also underwent the formation process before the electrodes were used tomake non-blocking configuration sym. and full coin cells. Through the use of temperature dependent measurements on blocking and non-blocking cells, the impedance contribution due to faradaic, charge transfer interactions can be distinguished from non-faradaic, high frequency impedance contributions. Fitting the EIS spectra allowed both the charge transfer resistances and the related capacitances to be determined for the solid electrolyte interphase layers on the neg. and pos. electrodes. The charge transfer resistances were strongly temperature dependent while the capacitances were not. The temperature dependence of the charge transfer resistance was used to determine the activation energies for lithium transport through the solid electrolyte interphase layers on the neg. and pos. electrodes. Surprisingly, the activation energies were approx. 0.6 eV for both pos. and neg. electrodes extracted from cells after formation.

《Scanning micro X-ray fluorescence (μXRF) as an effective tool in quantifying Fe dissolution in LiFePO4 cells: towards a mechanistic understanding of Fe dissolution》 was written by Eldesoky, A.; Logan, E. R.; Johnson, M. B.; McFarlane, C. R. M.; Dahn, J. R.. Name: Vinylene carbonate And the article was included in Journal of the Electrochemical Society in 2020. The article conveys some information:

Lithium iron phosphate (LiFePO4, or LFP) is a widely used cathode material in Li-ion cells due to its improved safety and low cost relative to other materials such as LiNixMnyCozO2 (x + y + z = 1, NMC). To improve the calendar life of LFP cells, an investigation of their failure mechanisms is necessary. Herein, the scanning micro X-ray fluorescence (μXRF) is used to study Fe dissolution from LFP and deposition on the graphite electrode, which is thought to be a contributor to capacity fade. The impacts of the vinylene carbonate (VC) electrolyte additive, cycling conditions, and water content in the pos. electrode on Fe dissolution were studied. There was no significant correlation between Fe dissolution and capacity fade found. Furthermore, it is proposed that gas generation concomitant with Fe dissolution might be due to the reduction of the organic species coordinating Fe2+ when they reach the neg. electrode. Localized regions of increased Fe loading on the anode surface were found, which corresponded to regions with slight non-uniformities in stack pressure or c.d. This work demonstrates the effectiveness of μXRF in quantifying transition metal (TM) dissolution in Li-ion cells without any sample treatments that might mask valuable information such as element spatial distribution.Vinylene carbonate(cas: 872-36-6Name: Vinylene carbonate) was used in this study.

《Effect of duty cycle on the lifetime of single crystal LiNi0.5Mn0.3Co0.2O2/graphite lithium-ion cells》 was written by Cheng, J. H.; Harlow, J. E.; Johnson, M. B.; Gauthier, Roby; Dahn, J. R.. Related Products of 872-36-6 And the article was included in Journal of the Electrochemical Society in 2020. The article conveys some information:

The effects of different duty cycles, involving mixtures of charge-discharge cycling and open-circuit storage segments, on the lifetime of single crystal NMC532/graphite cells were studied. Charge-discharge cycling was performed at C/3 with open circuit storage times of 0, 12, 84, 180 h or 3 mo applied at upper cutoff voltages (UCV) of 4.1, 4.2 and 4.3 V. Testing was made at 40°C for a period of 2.5 years. Cells tested to the same UCV showed similar capacity loss and impedance growth with time, independent of the ratio between the time spent cycling or in storage. Differential voltage anal. showed that the vast majority of the capacity loss stemmed from lithium inventory loss at the neg. electrode with little or no loss of active materials. The thickness of the pouch cells after testing increased with the fraction of time spent cycling and the amount of gas generated in the cells increased with fraction of time spent in storage at the UCV. These results show that cycled and stored cells age differently, even though a similar capacity fade rate was observed in the first 2.5 years of cell life, which may cause different failure modes at the end of cell life. In the experiment, the researchers used many compounds, for example, Vinylene carbonate(cas: 872-36-6Related Products of 872-36-6)

《Exploring the impact of key assembling parameters on the electrochemical performance of lithium metal symmetry cell》 was written by Wen, Zhipeng; Lin, Yinxin; Peng, Yueying; Zeng, Jing; Zhao, Jinbao. Application of 872-36-6 And the article was included in Journal of the Electrochemical Society in 2020. The article conveys some information:

With the urgent demand for higher energy d. storage system, much attention has been focused on the Li metal based batteries. During the exploration of new strategy for the Li metal protection, numerous researches are based on Li/Li symmetry cell for galvanostatic cycling tests. Here, the relationship between some exptl. parameters (size of Li foil, thickness of separator and electrolyte amount) and Li/Li symmetry cell cycling performance are systematically explored. It was found that the cycling stability of Li/Li symmetry cell has been significantly improved when the size of Li foil decreases or the thickness of separator increases. In the designed experiments, it can be seen that the failure of most of cells is attributed to the decrease in ions transport ability due to continuous consumption of the electrolyte and continuous increase of dead Li. At last, the investigation of electrolyte amounts reveals that Li/Li symmetry cell exhibits lower Li deposition overpotential and longer cycling life as adding more electrolytes. Therefore, the work suggests that research on the protection of electrolyte is very important issue in promoting the commercialization of Li metal batteries. Standardizing exptl. parameters during the experiment can make more efficient comparison of different literature results achieved. The results came from multiple reactions, including the reaction of Vinylene carbonate(cas: 872-36-6Application of 872-36-6)

The title of the article was 《Interfacial Reactivity of Silicon Electrodes: Impact of Electrolyte Solvent and Presence of Conductive Carbon》.Reference of Vinylene carbonate The author mentioned the following in the article:

Silicon (Si) is a promising high-capacity material for lithium-ion batteries; however, its limited reversibility hinders com. adoption. Approaches such as particle and crystallite size reduction, introduction of conductive carbon, and use of different electrolyte solvents have been explored to overcome these electrochem. limitations. Herein, operando isothermal microcalorimetry (IMC) is used to probe the influence of silicon particle size, electrode composition, and electrolyte additives fluoroethylene carbonate and vinylene carbonate on the heat flow during silicon lithiation. The IMC data are complemented by X-ray photoelectron and Raman spectroscopies to elucidate differences in solid electrolyte interphase (SEI) composition Nanosized (~50 nm, n-Si) and micrometer-sized (~4μm, μ-Si) silicon electrodes are formulated with and without amorphous carbon and electrochem. lithiated in ethylene carbonate (EC), fluoroethylene carbonate (FEC), or vinylene carbonate (VC) based electrolytes. Notably, n-Si electrodes generate 53-61% more normalized heat relative to their μ-Si counterparts, consistent with increased surface area and electrode/electrolyte reactivity. Introduction of amorphous carbon significantly alters the heat flow profile where multiple exothermic peaks and increased normalized heat dissipation are observed for all electrolyte types. Notably, the VC-containing electrolyte demonstrates the greatest normalized heat dissipation of the electrode compositions tested showing as much as a 50% increase compared to the EC or FEC counterparts. The results are relevant to the understanding of silicon neg. electrode function in the presence of electrolyte additives and provide insight relative to silicon containing cell reactivity and safety.Vinylene carbonate(cas: 872-36-6Reference of Vinylene carbonate) was used in this study.
