A rhodium(III)-catalyzed formal C-H [5 + 1] cyclization of 2-pyrrolyl/indolylanilines with vinylene carbonate was explored for synthesis of 4-methylpyrrolo[1,2-a]quinoxalines such as I [R1 = H, 8-OMe, 7-OTs, etc.; R = H, 1,3-di-Me] and 6-methylindolo[1,2-a]quinoxaline such as II [R1 = H, 2-F, 2-Cl; R = H, 9-OMe, 9-Br, etc.]. This established protocol was characterized by an exceedingly simple reaction system and excellent functional group toleration and yields. Most importantly, entirely distinct from documented [4 + 2] cyclization conversions, herein, the emerging vinylene carbonate firstly presented as a C1 synthon to realize [5 + 1] annulation and showed new chem. reactivity. Biol. studies indicated that few of these prepared I and II products were promising candidates in terms of their antibacterial activity. The results came from multiple reactions, including the reaction of Vinylene carbonate(cas: 872-36-6Recommanded Product: 872-36-6)

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.

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.

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.

《A Designed Durable Electrolyte for High-Voltage Lithium-Ion Batteries and Mechanism Analysis》 was written by Zou, Yeguo; Shen, Yabin; Wu, Yingqiang; Xue, Hongjin; Guo, Yingjun; Liu, Gang; Wang, Limin; Ming, Jun. Category: esters-buliding-blocks And the article was included in Chemistry – A European Journal in 2020. The article conveys some information:

Rechargeable lithium-ion batteries (LIBs) dominate the energy market, from electronic devices to elec. vehicles, but pursuing greater energy d. remains challenging owing to the limited electrode capacity. Although increasing the cut-off voltage of LIBs (>4.4 V vs. Li/Li+) can enhance the energy d., the aggravated electrolyte decomposition always leads to a severe capacity fading and/or expiry of the battery. Herein, a new durable electrolyte is reported for high-voltage LIBs. The designed electrolyte is composed of mixed linear alkyl carbonate solvent with certain cyclic carbonate additives, in which use of the ethylene carbonate (EC) co-solvent was successfully avoided to suppress the electrolyte decomposition As a result, an extremely high cycling stability, rate capability, and high-temperature storage performance were demonstrated in the case of a graphite|LiNi0.6Co0.2Mn0.2O2 (NCM622) battery at 4.45 V when this electrolyte was used. The good compatibility of the electrolyte with the graphite anode and the mitigated structural degradation of the NCM622 cathode are responsible for the high performance at high potentials above 4.4 V. This work presents a promising application of high-voltage electrolytes for pursuing high energy LIBs and provides a straightforward guide to study the electrodes/electrolyte interface for higher stability.

《Irreversible dilation of graphite composite anodes influenced by vinylene carbonate》 was published in Journal of Power Sources in 2020. These research results belong to Ivanov, Svetlozar; Sauerteig, Daniel; Dimitrova, Anna; Krischok, Stefan; Bund, Andreas. Recommanded Product: 872-36-6 The article mentions the following:

The volumetric expansion of graphite composite electrodes for Li ion battery is studied by electrochem. dilatometry in electrolytes with different concentration of vinylene carbonate (VC). While the reversible dilation of the anode coatings is not influenced by the VC concentration the irreversible part displays a strong dependence. With the increase of VC amount in the electrolyte the irreversible dilation decreases significantly, showing that the addition of VC has a pos. effect on the mech. performance of the battery. The observed behavior is associated with differences in the decomposition mechanism of the electrolyte components and their reaction kinetics, influenced by the presence of VC. In contrast to the VC containing electrolyte, the passivation layer formed on the anode in the absence of VC cannot effectively terminate the electroactivity of the graphite surface and the electron charge transfer. This leads to a continuous incorporation of decomposition products in the composite layer during the subsequent cycles and related to this addnl. irreversible volume expansion. The anal. performed by combined application of dilatometric, impedance and XPS techniques reveals the pos. role of VC for improving the electrochem.-mech. properties of the graphite porous anode.Vinylene carbonate(cas: 872-36-6Recommanded Product: 872-36-6) was used in this study.

When creating an estimation model, determining which variables are efficient is of considerable importance. To strictly select efficient variables, it is necessary to define appropriate criteria for the task and to perform an exhaustive search, which is the search method that evaluates and compares all variable combinations. In this study, we apply an exhaustive search with a Gaussian process (ES-GP) to estimate coordination energy, which is related to performance of a Li-ion battery, and show that the estimation accuracy of ES-GP is significantly better than that of other methods in previous studies, such as MLR, LASSO and ES-LiR.

Recommanded Product: Vinylene carbonate And the article was included in ACS Applied Materials & Interfaces in 2020. The article conveys some information:

Lithium-ion batteries (LIBs) with high-nickel (Ni) content LiNixMnyCozO2 (x + y + z = 1) (NMC with Ni ≥ 0.6) cathodes operated at high charge voltages have been considered as one of the most promising candidates for addressing the challenge of increasing energy d. demand. Conventional LiPF6-organocarbonate electrolytes exhibit incompatibility with such cell chemistries under certain testing conditions because of the instability of electrode/electrolyte interphases. In response to this challenge, ether-based electrolytes with finely tuned structure and composition of solvation sheaths were developed and evaluated in graphite (Gr)‖NMC811 cell chem. in 2.5-4.4 V, despite ethers being conventionally considered to be unfavorable electrolyte solvents for LIBs because of their anodic instability above 4.0 V and cointercalation into Gr electrodes. The functional ether-based electrolytes in this work enable both excellent cycle life and high rate capability of Gr‖NMC811 cells. Mechanistic studies reveal that the unique structure and composition of the solvation sheath of the functional ether electrolytes are the main reasons behind their excellent anodic stability and effective protection of the Gr electrode and, consequently, the extraordinary cell performances when operated at high charge cutoff voltages. This work also provides a feasible approach in developing highly stable functional electrolytes for high-energy d. LIBs.

The article was titled 《Reaction Mechanisms of the Degradation of Fluoroethylene Carbonate, an Additive of Lithium-Ion Batteries, Unraveled by Radiation Chemistry》, and you may find the article in Chemistry – A European Journal.Name: Vinylene carbonate The information in the text is summarized as follows:

Numerous additives are used in the electrolytes of lithium-ion batteries, especially for the formation of an efficient solid electrolyte interphase at the surface of the electrodes. Understanding the degradation processes of these compounds is thus important; they can be seen through radiolysis. In the case of fluoroethylene carbonate (FEC), picosecond pulse radiolysis experiments evidenced the formation of FEC.-. This radical is stabilized in neat FEC, whereas the ring opens to form more stable radical anions when FEC is a solute in other solvents, as confirmed by quantum chem. calculations In neat FEC, pre-solvated electrons primarily undergo attachment rather than solvation. On long timescales, the gases produced (H2, CO, and CO2) were quantified. A reaction scheme for both the oxidizing and reducing pathways at stake in irradiated FEC is proposed. This work shows that the nature of the primary species formed in FEC depends on the amount of FEC in the solutionVinylene carbonate(cas: 872-36-6Name: Vinylene carbonate) was used in this study.
