Application In Synthesis of Vinylene carbonateIn 2020 ,《Studies of the SEI layers in Li(Ni0.5Mn0.3Co0.2)O2/rtificial graphite cells after formation and after cycling》 was published in Journal of the Electrochemical Society. The article was written by Keefe, A. S.; Weber, Rochelle; Hill, I. G.; Dahn, J. R.. The article contains the following contents:

Li(Ni0.5Mn0.3Co0.2)O2/artificial graphite cells containing different electrolyte additives were studied using electrochem. impedance spectroscopy (EIS) and XPS after formation and after long-term charge-discharge cycling. Pos. and neg. electrodes were examined sep. in sym. cells to study the solid electrolyte interphase (SEI) at Each electrode. EIS measurements were taken vs. temperature, and activation energies (Ea) related to Li+ transport through the SEI were calculated After cycling, Ea differed depending on electrolyte additive, electrode type, and cycling voltage limits. Charge transfer resistance was also compared after formation and cycling and did not always correlate with Ea trends, suggesting that multiple factors influence SEI properties. XPS was used to study the chem. composition and thickness of the SEI. Electrolyte additives affected the quantity of inorganic materials in the SEI, and more inorganic material appeared to correlate with lower Ea values. Cells containing Li difluorophosphate electrolyte additive had the best lifetime of the cells studied. These cells also showed the lowest SEI activation energy values, lowest charge transfer resistance, and most inorganic SEI composition after cycling. The results came from multiple reactions, including the reaction of Vinylene carbonate(cas: 872-36-6Application In Synthesis of Vinylene carbonate)

《Fire-Preventing LiPF6 and Ethylene Carbonate-Based Organic Liquid Electrolyte System for Safer and Outperforming Lithium-Ion Batteries》 was written by Chung, Gyeong Jun; Han, Jisoo; Song, Seung-Wan. Reference of Vinylene carbonate And the article was included in ACS Applied Materials & Interfaces in 2020. The article conveys some information:

Battery safety is an ever-increasing significance to guarantee consumer’s safety. Reducing or preventing the risk of battery fire and explosion is a must for battery manufacturers. Major reason for the occurrence of fire in com. lithium-ion batteries is the flammability of conventional organic liquid electrolyte, which is typically composed of 1 M LiPF6 salt and ethylene carbonate (EC)-based organic solvents. Herein, we report the designed 1 M LiPF6 and EC-based nonflammable electrolyte including methyl(2,2,2-trifluoroethyl)carbonate, which breaks the conventional perception that EC-based liquid electrolyte is always flammable. The designed electrolyte also provides high anodic stability beyond the conventional charge cut-off voltage of 4.2 V. A graphite‖LiNi0.6Co0.2Mn0.2O2 lithium-ion full cell with our designed EC-based nonflammable electrolyte with a small fraction of vinylene carbonate additive under an aggressive condition of 4.5 V charge cut-off voltage, 0.5C rate, and 45°C exhibits increased capacity, reduced interfacial resistance, and improved performance and rate capability. A basic understanding of how a high-voltage cathode-electrolyte interface and anode-electrolyte interface are stabilized and how failure modes are mitigated by fire-preventing electrolyte is discussed. After reading the article, we found that the author used Vinylene carbonate(cas: 872-36-6Reference of Vinylene carbonate)

Omale, Joel O.; Van Velthem, Pascal; Antohe, Vlad-Andrei; Vlad, Alexandru; Piraux, Luc published an article in 2021. The article was titled 《Effects of Electrolyte Additives and Nanowire Diameter on the Electrochemical Performance of Lithium-Ion Battery Anodes based on Interconnected Nickel-Tin Nanowire Networks》, and you may find the article in Energy Technology (Weinheim, Germany).HPLC of Formula: 872-36-6 The information in the text is summarized as follows:

Tin-based nanowire electrodes present desirable properties as lithium-ion battery anodes, because they undergo volume changes without pulverization. However, they suffer from limited mass loading and propensity for surface parasitic reactions. Herein, the electrochem. performances of nickel-tin 3D-interconnected nanowire network (NiSn 3DNWN) electrodes are evaluated with the nanowire diameters of 40, 105, and 230 nm, resp., that attain mass loadings of up to 3 mg cm-2. To mitigate the surface parasitic reactions, the effects of fluoroethylene carbonate (FEC) and vinylene carbonate (VC) additives are investigated as a function of the nanowire diameter and additive concentration The results show that the FEC and VC of all compositions improve the capacity retentions and coulombic efficiencies (CEs) of the NiSn 3DNWN electrodes. In 10 vol% FEC, the electrodes demonstrate a similar capacity of ≈550 mAh g-1, but the capacity retentions after 100 cycles are 73.68%, 53.79%, and 51.70% for the 40, 105, and 230 nm NiSn 3DNWN, resp. However, the 105 nm-diameter nanowire electrode has the highest average CE of 96.55%. Electrochem. impedance spectroscopy and post-cycling investigations reveal that the FEC has the most profound effect on the interfacial resistances, which is reflected in the rate performances of the tested electrodes.

In 2019,Journal of the Electrochemical Society included an article by Hall, David S.; Li, Jing; Lin, Katherine; Stakheiko, Nikolai; Baltazar, Jazmin; Dahn, J. R.. Recommanded Product: Vinylene carbonate. The article was titled 《Two additives: effects of glutaric and citraconic anhydrides on Lithium-ion cell performance》. The information in the text is summarized as follows:

The use of electrolyte additives is an important method to improve lithium-ion cell lifetime and performance without significantly affecting costs. This work evaluates two organic anhydrides, glutaric anhydride (GA) and citraconic anhydride (CA), as additives in Li(Ni0.6Mn0.2Co0.2)O2 (NMC622)/graphite and Li(Ni0.5Mn0.3Co0.2)O2 (NMC532)/graphite pouch cells, using ultrahigh precision coulometry and high-temperature storage. The additives were tested singly and in binary blends. GA-based additive blends give high coulombic efficiencies (CEs) and good storage performance. However, GA leads to substantial impedance during formation. Most notably, GA is extremely effective at suppressing gas during cell formation and storage. Whereas CA-containing blends yield good CEs, they show rapid voltage drop during storage. Both additives may provide specific benefits for target applications. Long-term cycling data indicates that GA is a neg. electrode SEI-forming additive that is useful for capacity retention and limiting cell impedance growth when used as a binary blend with vinylene carbonate or lithium difluorophosphate. These results are also intended to facilitate comparison between chem. related additives in order to better understand the underlying chem. behind their function in lithium-ion cells. In the part of experimental materials, we found many familiar compounds, such as Vinylene carbonate(cas: 872-36-6Recommanded Product: Vinylene carbonate)

In 2019,Journal of the Electrochemical Society included an article by Gauthier, Roby; Hall, David S.; Taskovic, T.; Dahn, J. R.. Product Details of 872-36-6. The article was titled 《A joint DFT and experimental study of an imidazolidinone additive in lithium-ion cells》. The information in the text is summarized as follows:

Electrolyte additives are a practical route to improving the lifetime and performance of lithium-ion cells. It is not well understood what makes a good additive; thus, the discovery of new additives poses a significant challenge. Computational methods have the potential to streamline the search for new additives, but it is important to compare predicted additive behavior with exptl. measured results. A new electrolyte additive, 1,3-dimethyl-2-imidazolidinone (DMI), has been evaluated in LiNi1-x-yMnxCoyO2 (NMC)/graphite pouch cells as a single additive and with the co-additive vinylene carbonate (VC). This work compares the d. functional theory (DFT)-predicted behavior of DMI with exptl. results, including differential capacity anal. (dQ/dV), electrochem. impedance spectroscopy (EIS), high-temperature storage, gas chromatog.-mass spectrometry (GC-MS) and long-term cycling tests. The DFT-calculated reduction potential of DMI is -0.63 V vs Li/Li+, consistent with the exptl. observation that it reduces at a lower potential than ethylene carbonate (EC), ∼0.80 V vs Li/Li+. Although DMI turns out not to be a competitively useful additive, the good match between many aspects of the exptl. results and theor. predictions is a good indication that it is possible to understand aspects of the behavior of additives. This can guide future researchers. In addition to this study using Vinylene carbonate, there are many other studies that have used Vinylene carbonate(cas: 872-36-6Product Details of 872-36-6) was used in this study.

《Flexible Interface Design for Stress Regulation of a Silicon Anode toward Highly Stable Dual-Ion Batteries》 was written by Jiang, Chunlei; Xiang, Lei; Miao, Shijie; Shi, Lei; Xie, Donghao; Yan, Jiaxiao; Zheng, Zijian; Zhang, Xiaoming; Tang, Yongbing. HPLC of Formula: 872-36-6 And the article was included in Advanced Materials (Weinheim, Germany) in 2020. The article conveys some information:

Dual-ion batteries (DIBs) have attracted increasing attention due to their high working voltage, low cost, and environmental friendliness, yet their development is hindered by their limited energy d. Pairing silicon-a most promising anode due to its highest theor. capacity (4200 mAh g-1)-with a graphite cathode is a feasible strategy to address the challenge. Nevertheless, the cycling stability of silicon is unsatisfactory due to the loss of elec. contact resulting from the high interface stress when using rigid current collectors. In this work, a flexible interface design to regulate the stress distribution is proposed, via the construction of a silicon anode on a soft nylon fabric modified with a conductive Cu-Ni transition layer, which endows the silicon electrode with remarkable flexibility and stability over 50 000 bends. Assembly of the flexible silicon anode with an expanded graphite cathode yields a silicon-graphite DIB (SGDIB), which possesses record-breaking rate performance (up to 150 C) and cycling stability over 2000 cycles at 10 C with a capacity retention of 97%. Moreover, the SGDIB shows a high capacity retention of ≈84% after 1500 bends and a low self-discharging voltage loss of 0.0015% per bend after 10 000 bends, suggesting high potential for high-performance flexible energy-storage applications.

《New Interpretation of X-ray Photoelectron Spectroscopy of Imidazolium Ionic Liquid Electrolytes Based on Ionic Transport Analyses》 was written by Morales-Ugarte, J. E.; Santini, C. C.; Bouchet, R.; Benayad, A.. SDS of cas: 872-36-6This research focused onXPS imidazolium ionic liquid electrolytes transport analysis. The article conveys some information:

We reported a new perspective on the correlation between the electronic structure of an ionic liquid (IL)-based electrolyte probed by XPS and the transport properties analyzed by impedance spectroscopy. We highlighted the core level chem. shifts of 1-hexyl-3-methylimidazolium (bis(trifluoromethanesulfonyl)imide) (C1C6ImTFSI), 1-hexyl-3-methylimidazolium bis(fluorosulfonyl)imide (C1C6ImFSI), and 1-hexyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide (C1C1C6ImTFSI) laden with LiTFSI salt and vinylene carbonate (VC) or fluoroethylene carbonate (FEC) with regard to the transport properties of cations and anions. We pointed out based on detailed binding energy shift analyses a clear effect of the anion on the local organization of Li+ ions. The significant peak shift in the case of C1C6ImTFSI laden with LiTFSI corroborates the formation of [Li(TFSI)2]- complexes. On the contrary, the lower amplitude of the binding energy shift of C1C6ImFSI for both anion- and cation-related peaks indicates that the electronic distribution around the cation and the anion is not affected when the LiTFSI salt is added, which plays a strong role in the ion dynamics (lower viscosity) of the electrolyte. The XPS result supports the preponderant role of imidazolium ionic liquid based on FSI anion to form an electrolyte less prone to form ionic complexes. The methylation of the imidazolium cation contributes to the reduction of the interaction between the C1C1C6Im cation and TFSI anion, while additives VC and FEC contribute to the change of the alkyl configuration in C1C6Im cation, leading to the modification of the macroscopic properties of the ILs.

In 2019,Journal of the Electrochemical Society included an article by Schwenke, K. Uta; Solchenbach, Sophie; Demeaux, Julien; Lucht, Brett L.; Gasteiger, Hubert A.. Synthetic Route of C3H2O3. The article was titled 《The impact of CO2 evolved from VC and FEC during formation of graphite anodes in lithium-ion batteries》. The information in the text is summarized as follows:

Additives such as vinylene carbonate (VC) and fluoroethylene carbonate (FEC) are commonly added to Li-ion battery electrolytes in order to form a solid electrolyte interphase (SEI) on the anode, suppressing continuous solvent reduction Here, we directly compare VC and FEC by analyzing the SEI with FTIR and XPS, and the evolved gases with online electrochem. mass spectrometry (OEMS) in different model systems. Since both additives evolve mainly CO2 during formation, the effect of CO2 as an additive is compared to the addition of VC and FEC. While Li2CO3 is as expected the main SEI compound found due to the added CO2, surprisingly no CO was detected in the gas phase of such cells. Based on FTIR, NMR and OEMS analyses of cells filled with 13C labeled CO2, we suggest a mechanism explaining the beneficial effects of CO2 and hence also of CO2 evolving additives in lithium-ion battery cells. While the generation of polycarbonate from FEC or VC reduction is observed, the generation of Li2CO3 may be as important as the generation of polycarbonate. In addition to this study using Vinylene carbonate, there are many other studies that have used Vinylene carbonate(cas: 872-36-6Synthetic Route of C3H2O3) was used in this study.

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:

1-Ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (EMI-TFSA) is one of the promising ionic liquids as electrolyte solvent to enhance the electrochem. performance of Si electrode for Li-ion batteries (LIBs) because of its low viscosity and high conductivity However, it has low stability against reduction and its reductive decomposition product inhibits Li+ insertion to electrodes, leading to poor cycling stability. To exert a potential of EMI-TFSA, we employed vinylene carbonate (VC) as film-forming additive. Si electrode exhibited very high cycling stability and rate capability in 20 volume% VC-added EMI-TFSA-based electrolyte. In addition, by replacing TFSA anion with bis(fluorosulfonyl)amide (FSA) for Li salt and ionic liquid solvent, an excellent cycling performance and outstanding rate capability was achieved. VC cannot only fabricate a good surface film but also lower the interaction between Li+ and FSA-, providing smooth desolvation of FSA- to obtain better high-rate performance. Non-flammability of the VC-added electrolytes was confirmed by fire resistance test in closed-system: no ignition was observed even at 300°C. Consequently, we found that mixture electrolyte consisted of EMI-based ionic liquid and VC, especially 1 M LiFSA/EMI-FSA with 20 volume% VC, is a prospective candidate for simultaneously enhancing the electrochem. performance of Si electrode as well as safety of LIBs. In the experiment, the researchers used many compounds, for example, Vinylene carbonate(cas: 872-36-6Electric Literature of C3H2O3)

《Vinylene-bridged cyclic dipyrrin and BODIPY trimers》 was published in International Journal of Molecular Sciences in 2020. These research results belong to Xue, Songlin; Kuzuhara, Daiki; Aratani, Naoki; Yamada, Hiroko. SDS of cas: 872-36-6 The article mentions the following:

Vinylene-bridged cyclic boron-difluoride complex of dipyrrin (BODIPY) trimers were successfully prepared from expanded dimethyl-vinylene bridged hexaphyrin(2.1.2.1.2.1) Me-Hex that has the structure of alternate dipyrrins and vinylene bridges. The hexaphyrin(2.1.2.1.2.1) Me-Hex can coordinate with boron ions to afford five kinds of cyclic BODIPYs given by step-by-step boron complexations. Crystal structures of all cyclic BODIPYs except for 3BF2-Me-Hex(b) formed non-planar structures. The theor. calculation predicted that mono-/bis-boron cyclic BODIPYs show the intramol. charge transfer (ICT) characteristics, whereas tri-boron cyclic BODIPYs have no ICT characteristics. Reflecting these electronic properties, tri-boron cyclic BODIPYs exhibit weak fluorescence in the red region, but mono-/bis-boron cyclic BODIPYs exhibit no emission. Vinylene bridged cyclic dipyrrin trimer Me-Hex is the novel porphyrinoid ligand allowed to control the boron coordination under different reaction conditions to form various boron complexes. In the experiment, the researchers used many compounds, for example, Vinylene carbonate(cas: 872-36-6SDS of cas: 872-36-6)
