LiNi0.6Mn0.2Co0.2O2 attracts increasing attention in industry due to its high energy d. Vinylene carbonate and 1,3-propane sultone are engaged to enhance the high-temperature performance of LiNi0.6Mn0.2Co0.2O2/artificial graphite pouch cells in this work. With the addition of the additives, the capacity retention of the full cell reaches 98% after 200 cycles at 45 °C and 500 mA. Meanwhile, the underneath mechanism is investigated by employing XPS, gas chromatograph-mass spectrometer and liquid chromatog.-quadruple time of flight mass spectrometry measurements. The results show that the additives can not only protect the anode, but also shelter the cathode. It is of great interest that vinylene carbonate can suppress the decomposition of electrolyte, leading to less organic species in electrolyte, more stable interfaces. The addition of 1,3-propane sultone takes part in the generation of sulfonates after formation, which can be reduced to sulfides upon cycling. The combination of these two additives can optimize the interfacial reactions, as well as can suppress the decomposition of electrolytes and the dissolution of manganese, which leads to much better high-temperature storage performance and cycling performance of the full cells. In the part of experimental materials, we found many familiar compounds, such as Vinylene carbonate(cas: 872-36-6Reference of Vinylene carbonate)

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

The author of 《Understanding the Role of Fluorination on the Interaction of Electrolytic Carbonates with Li+ through an Electronic Structure Approach》 were Kushwaha, Anoop Kumar; Sahoo, Mihir Ranjan; Nayak, Saroj Kumar. And the article was published in ChemistrySelect in 2019. Name: Vinylene carbonate The author mentioned the following in the article:

The donor-acceptor orbital interaction between the unoccupied orbital of Li+ and the lone pair of oxygen atoms in the carbonyl group of Li+-carbonate complexes shows significant decrease on fluorination. This has been investigated through MO formalism based d. functional theory. The fluorination process lowers the binding energy (reduced up to 13.8 kcal/mol), and widens the HOMO-LUMO gap (enhanced up to 0.7 eV), which is essential for achieving electrolytes with high potential window in Li-ion battery. Furthermore, the impact of fluorination on few critical factors has been observed, i. e. dipole moment (drastic enhancement), IR spectra (most affected C=O vibrational mode shows blue shift in the spectra) and Raman active mode (carbonyl group stretching mode doublet (νCO) shifted to higher frequency) which have been probed by vibrational frequency anal. In the experiment, the researchers used many compounds, for example, Vinylene carbonate(cas: 872-36-6Name: Vinylene carbonate)

Vinylene carbonate(cas: 872-36-6) belongs to esters.

HPLC of Formula: 872-36-6In 2019 ,《Silica from diatom frustules as anode material for Li-ion batteries》 was published in RSC Advances. The article was written by Norberg, Andreas Nicolai; Wagner, Nils Peter; Kaland, Henning; Vullum-Bruer, Fride; Svensson, Ann Mari. The article contains the following contents:

In spite of its insulating nature, SiO2 may be utilized as active anode material for Li-ion batteries. Synthetic SiO2 will typically require sophisticated synthesis and/or activation procedures in order to obtain a satisfactory performance. Here, we report on diatom frustules as active anode material without the need for extensive activation procedures. These are composed primarily of silica, exhibiting sophisticated porous structures. Various means of optimizing the performance were investigated. These included carbon coating, the addition of fluoroethylene carbonate (FEC) and vinylene carbonate (VC) to the carbonate-based electrolyte, as well as activation by an initial potentiostatic hold step. The highest capacity (723 mA h g-1) was obtained with composite electrodes with pristine diatom frustules and conventional carbon black as additive, with the capacity still increasing after 50 cycles. The capacity was around 624 mA h g-1 after subtraction of the contributions from the carbon black. Carbon coated diatom frustules showed a slightly lower but stable capacity after 50 cycles (600 mA h g-1 after subtraction of contributions from the carbon coating and the carbon black). By the use of electrochem. characterization methods, as well as post-mortem studies, differences in reaction mechanisms could be identified and attributed to the operating and processing parameters. In the experiment, the researchers used many compounds, for example, Vinylene carbonate(cas: 872-36-6HPLC of Formula: 872-36-6)

Leissing, Marco; Peschel, Christoph; Horsthemke, Fabian; Wiemers-Meyer, Simon; Winter, Martin; Nowak, Sascha published an article in 2021. The article was titled 《The Origin of Gaseous Decomposition Products Formed During SEI Formation Analyzed by Isotope Labeling in Lithium-Ion Battery Electrolytes》, and you may find the article in Batteries & Supercaps.Quality Control of Vinylene carbonate The information in the text is summarized as follows:

Interphase formation during the first charge and discharge cycle(s) of a battery cell is among the least understood processes in lithium-ion batteries (LIBs). The formation of interphases is a result of electrolyte decomposition and accompanied by gassing. The direct anal. of these interphases is challenging and indirect methods are required to obtain information about this process. For example, indirect, ex situ analyses of gaseous decomposition products can help to draw conclusions about occurring reactions in the cell. In this work, the origin of several permanent gases and hydrocarbons (CO, CH4, C2H4 and C2H6) emerging during the formation of LiNi0.6Mn0.2Co0.2O2 (NMC622)||graphite pouch type LIBs equipped with a gas sampling port was investigated. Isotope labeled electrolytes (13C3-EC, D4-EC) were used to assign formation gas products to the individual constituents of the electrolyte mixture The effect of common linear carbonates in combination with ethylene carbonate (EC) as well as the effect of vinylene carbonate (VC) as film forming additive was investigated. The obtained mass spectra from gas chromatog. mass spectrometry (GC-MS) and the mass shift caused by the labeled electrolyte components, enabled an assignment of individual electrolyte components to the resulting gas products. The aim of this work is to gain more information about interphase reactions and thus to improve understanding of the mechanisms behind formation.Vinylene carbonate(cas: 872-36-6Quality Control of Vinylene carbonate) was used in this study.

《Activated Isobutylene-Isoprene Rubber-Synthesis, Peroxide Cure, and Mechanical Properties》 was written by Sun, Yu; Fan, Chengkai; Wei, Benqian; Wesdemiotis, Chrys; Jia, Li. Name: Ethyl propiolate And the article was included in ACS Applied Polymer Materials in 2020. The article conveys some information:

EIIR, a derivative of isobutylene-isoprene rubber (IIR) with geminal vinylidene-acrylate motifs, has been synthesized by grafting Et propiolate to IIR via EtAlCl2-catalyzed Alder-ene reaction. Methods to cure EIIR using dicumyl peroxide (DCP) with m-phenylene-N,N’-bismaleimide (BMI) as the coagent have been successfully developed. The strength, extensibility, and overall toughness of the peroxide-cured EIIR significantly exceed those of previously reported peroxide-cured IIR derivatives The role of the germinal vinylidene-acrylate moiety in curing has been investigated via model reactions using small-mol. surrogates of the functionalities present in EIIR. Evidence from mass spectrometry suggests that the germinal vinylidene-acrylate moiety undergoes both radical addition and hydrogen abstraction. Its importance for the curing process is further demonstrated by the ability of its small-mol. surrogate, Et 4,5-dimethyl-(E-2),5-hexdienoate (EDHEX), to reduce chain scission when used as a coagent in conjunction with BMI. The excellent mech. properties and the simplicity of the curing package make the peroxide-cured EIIR a strong candidate for pharmaceutical closure applications.Ethyl propiolate(cas: 623-47-2Name: Ethyl propiolate) was used in this study.

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.
