《Operando investigation of the solid electrolyte interphase mechanical and transport properties formed from vinylene carbonate and fluoroethylene carbonate》 was written by Kitz, Paul G.; Lacey, Matthew J.; Novak, Petr; Berg, Erik J.. Reference of Vinylene carbonate And the article was included in Journal of Power Sources in 2020. The article conveys some information:

The electrolyte additives vinylene carbonate (VC) and fluoroethylene carbonate (FEC) are well known for increasing the lifetime of a Li-ion battery cell by supporting the formation of an effective solid electrolyte interphase (SEI) at the anode. In this study combined simultaneous electrochem. impedance spectroscopy (EIS) and operando electrochem. quartz crystal microbalance with dissipation monitoring (EQCM-D) are employed together with in situ gas anal. (OEMS) to study the influence of VC and FEC on the passivation process and the interphase properties at carbon-based anodes. In small quantities both additives reduce the initial interphase mass loading by 30-50%, but only VC also effectively prevents continuous side reactions and improves anode passivation significantly. VC and FEC are both reduced at potentials above 1 V vs. Li+/Li in the first cycle and change the SEI composition which causes an increase of the SEI shear storage modulus by over one order of magnitude in both cases. As a consequence, the ion diffusion coefficient and conductivity in the interphase is also significantly affected. While small quantities of VC in the initial electrolyte increase the SEI conductivity, FEC decomposition products hinder charge transport through the SEI and thus increase overall anode impedance significantly.Vinylene carbonate(cas: 872-36-6Reference of Vinylene carbonate) was used in this study.

Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Reference of Vinylene carbonate

Electrolyte decomposition of lithium-ion battery as a consequence of thermal stress was investigated in Part 1 of this two-part study. The focus of Part 2 is on the influence of the battery cell operation conditions on the electrolyte during cell formation and long-term cycling. Especially, the reactivity of the neg. electrode surface and the varied properties of the formed solid electrolyte interphase via vinylene carbonate addition, changing the picture of decomposition products, were addressed. With the help of liquid chromatog. hyphenated to high-resolution mass spectrometry and fragmentation capabilities, structure elucidation was performed with optimal certainty. This Part 2 confirmed, summarized, and extended previous findings to 140 different carbonate, oligo phosphate, and mixed phosphate-carbonate species in the state-of-the-art electrolytes after moderate cycling conditions and contributes to a targeted investigation of LIB electrolyte aging processes. Furthermore, thermal and electrochem. aging phenomena were discussed and thermal stress-marker mols. that eased reversed-engineering were postulated.

《Solvent-free and montmorillonite K10-catalyzed domino reactions for the synthesis of pyrazoles with alkynylester as a dual synthon》 was written by Annes, Sesuraj Babiola; Saritha, Rajendhiran; Subramanian, Saravanan; Shankar, Bhaskaran; Ramesh, Subburethinam. Safety of Ethyl propiolateThis research focused ontrisubstituted pyrazole regioselective preparation; disubstituted pyrazole regioselective preparation; pyrazole alkynyl ester domino ring closing montmorillonite K10 catalyst. The article conveys some information:

A highly regioselective, solvent-free and montmorillonite K10 clay-catalyzed domino process with an unprecedented ring-closing C-C bond-formation reaction was described for the synthesis of a new class of 1,3,4-trisubstituted I [R = H, 4-Me, 3-Cl, etc.; R1 = R2 = CO2Me, CO2Et, CO2Bn, etc.] and 1,4-disubstituted pyrazole derivatives I [R2 = H]. The reaction proceeded via nucleophilic attack of enamine from an intermediate on the β-carbon of an amino acrylate. Exptl. outcomes clearly revealed that organic solvents had an adverse effect upon pyrazole formation and that an oxidative condition in the presence of the reusable clay favored formation of the 1,3,4-trisubstituted pyrazole. The clay in the presence of a N-bromosuccinamide catalyst gave the 1,4-disubstituted pyrazole after pyrolytic cleavage at elevated temperature The experimental process involved the reaction of Ethyl propiolate(cas: 623-47-2Safety of Ethyl propiolate)

HPLC of Formula: 872-36-6In 2019 ,《A New Electrolyte Formulation for Securing High Temperature Cycling and Storage Performances of Na-Ion Batteries》 was published in Advanced Energy Materials. The article was written by Yan, Guochun; Reeves, Kyle; Foix, Dominique; Li, Zhujie; Cometto, Claudio; Mariyappan, Sathiya; Salanne, Mathieu; Tarascon, Jean-Marie. The article contains the following contents:

The Na-ion battery is recognized as a possible alternative to the Li-ion battery for applications where power and cost override energy d. performance. However, the increasing instability of their electrolyte with temperature is still problematic. Thus, a central question remains how to design Na-based electrolytes. The discovery of a Na-based electrolyte formulation is reported which enlists four additives (vinylene carbonate, succinonitrile, 1,3-propane sultone, and sodium difluoro(oxalate)borate) in proper quantities that synergistically combine their pos. attributes to enable a stable solid electrolyte interphase at both neg. and pos. electrodes surface at 55°C. Moreover, the role of each additive that consists in producing specific NaF coatings, thin elastomers, sulfate-based deposits, and so on via combined impedance and XPS is rationalized. It is demonstrated that empirical electrolyte design rules previously established for Li-ion technol. together with theor. guidance is vital in the quest for better Na-based electrolytes that can be extended to other chemistries. Overall, this finding, which is implemented to 18 650 cells, widens the route to the rapid development of the Na-ion technol. based on Na3V2(PO4)2F3/C chem.

In this research, authors synthesized the Fe3O4/CuO/ZnO@MWCNT magnetic nanocomposites using water extract of Petasites hybridus rhizome, and the high performance of synthesized catalyst was confirmed by using in the solvent-free multicomponent reactions of isatoic anhydride, N-methylimidazole, alkyl bromides, activated acetylenic compounds and 2-aminoacetonitrile at ambient temperature for the production of new cyanopyrroloazepine derivatives in high yields. This catalyst could be used several times in these reactions and have main role in the yield of product. The synthesized cyanopyrroloazepines have NH groups in their structure and for this reason have good antioxidant activity. Also, employing Gram-pos. and Gram-neg. bacteria in the disk diffusion procedure confirmed some cyanopyrroloazepines antimicrobial effect.

《Additives Engineered Nonflammable Electrolyte for Safer Potassium Ion Batteries》 was written by Liu, Gang; Cao, Zhen; Zhou, Lin; Zhang, Jiao; Sun, Qujiang; Hwang, Jang-Yeon; Cavallo, Luigi; Wang, Limin; Sun, Yang-Kook; Ming, Jun. Formula: C3H2O3 And the article was included in Advanced Functional Materials in 2020. The article conveys some information:

Potassium ion batteries (KIBs) are attracting great attention as an alternative to lithium-ion batteries due to lower cost and better global sustainability of potassium. However, designing electrolytes compatible with the graphite anode and addressing the safety issue of highly active potassium remains challenging. Herein, a new concept of using additives to engineer non-flammable electrolytes for safer KIBs is introduced. It is discovered that the additives, such as the ethylene sulfate (i.e., DTD), can make the electrolyte of 1.0 M potassium bis(fluorosulfonyl) imide in tri-Me phosphate compatible with graphite anode for the first time, without the need of concentrated electrolyte strategies. A new coordination mechanism of additives in the electrolyte is presented. It is shown that the additive can change the K+ solvation structure and then determine the interfacial behaviors of K+-solvent on electrode interface, which are critical to affect the graphite performance (i.e., K+-solvent co-insertion, or K+ (de-)intercalation). Then, an extremely high potassium storage capability is obtained in graphite electrode for potassium (ion) batteries, particularly the presented high-performance graphite|K0.69CrO2 full battery fully demonstrates the practical application of this newly designed electrolyte. This additive-based strategy can offer more opportunities to tune the electrolyte properties and then serve for the more mobile ion battery system. In the experiment, the researchers used Vinylene carbonate(cas: 872-36-6Formula: C3H2O3)

Product Details of 872-36-6 And the article was included in Advanced Energy Materials in 2020. The article conveys some information:

LiNixMnyCo1-x-yO2 (NMC) cathode materials with Ni = 0.8 have attracted great interest for high energy-d. lithium-ion batteries (LIBs) but their practical applications under high charge voltages (e.g., 4.4 V and above) still face significant challenges due to severe capacity fading by the unstable cathode/electrolyte interface. Here, an advanced electrolyte is developed that has a high oxidation potential over 4.9 V and enables NMC811-based LIBs to achieve excellent cycling stability in 2.5-4.4 V at room temperature and 60°C, good rate capabilities under fast charging and discharging up to 3C rate (1C = 2.8 mA cm-2), and superior low-temperature discharge performance down to -30°C with a capacity retention of 85.6% at C/5 rate. It is also demonstrated that the electrode/electrolyte interfaces, not the electrolyte conductivity and viscosity, govern the LIB performance. This work sheds light on a very promising strategy to develop new electrolytes for fast-charging high-energy LIBs in a wide-temperature range. In the part of experimental materials, we found many familiar compounds, such as Vinylene carbonate(cas: 872-36-6Product Details of 872-36-6)
