《Lithium-ion attack on yttrium oxide in the presence of copper powder during Li plating in a super-concentrated electrolyte》 was written by Shiga, Tohru; Masuoka, Yumi; Nozaki, Hiroshi; Ohba, Nobuko. Computed Properties of C3H2O3This research focused onyttrium oxide copper powder lithium ion attack plating. The article conveys some information:

Li plating/stripping on Cu and Y2O3 (Cu + Y2O3) electrodes was examined in a super-concentrated electrolyte of lithium bis(fluorosulfonyl)amide and methylphenylamino-di(trifluoroethyl) phosphate. In principle, Li+ ions cannot intercalate into a Y2O3 crystal because its intercalation potential obtained from first-principles calculations is -1.02 V vs. Li+/Li. However, a drastic decrease in the electrode potential and a subsequent constant-potential region were observed during Li plating onto a Cu + Y2O3 electrode, suggesting that Li+ interacted with Y2O3. X-ray diffraction (XRD) patterns and X-ray absorption fine structure (XAFS) spectra of the Cu + Y2O3 electrodes after the Li plating were recorded to verify this phenomenon. The XRD and XAFS results indicated that the crystallinity of Y2O3 crystals was lowered because of attack by Li+ ions or that the Y2O3 crystal structure was broken while the +3 valence state of Y was maintained. After reading the article, we found that the author used Vinylene carbonate(cas: 872-36-6Computed Properties of C3H2O3)

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

Product Details of 872-36-6In 2019 ,《Polymer-inorganic solid-electrolyte interphase for stable lithium metal batteries under lean electrolyte conditions》 appeared in Nature Materials.

The article conveys some information:

The solid-electrolyte interphase (SEI) is pivotal in stabilizing Li metal anodes for rechargeable batteries. However, the SEI is constantly reforming and consuming electrolyte with cycling. The rational design of a stable SEI is plagued by the failure to control its structure and stability. Here the authors report a mol.-level SEI design using a reactive polymer composite, which effectively suppresses electrolyte consumption in the formation and maintenance of the SEI. The SEI layer consists of a polymeric Li salt, LiF nanoparticles and graphene oxide sheets, as evidenced by cryo-TEM, at. force microscopy and surface-sensitive spectroscopies. This structure is different from that of a conventional electrolyte-derived SEI and has excellent passivation properties, homogeneity and mech. strength. The use of the polymer-inorganic SEI enables high-efficiency Li deposition and stable cycling of 4 V Li|LiNi0.5Co0.2Mn0.3O2 cells under lean electrolyte, limited Li excess and high capacity conditions. The same approach was also applied to design stable SEI layers for Na and Zn anodes. In the experiment, the researchers used Vinylene carbonate(cas: 872-36-6Product Details of 872-36-6)

In 2022,Sathya, Swamickan; Angulakshmi, N.; Ahn, Jou-Hyeon; Kathiresan, M.; Stephan, A. Manuel published an article in Langmuir. The title of the article was 《Influence of additives on electrochemical and interfacial properties of SiOx-based anode materials for lithium-sulfur batteries》.Electric Literature of C3H2O3 The author mentioned the following in the article:

The influence of electrolyte additives on the electrochem. and interfacial properties of SiOx-based anodes for lithium-sulfur batteries (Li-S) was systematically investigated. Four different electrolyte additives, namely, lithium nitrate, vinylene carbonate (VC), vinyl ethylene carbonate, and fluoroethylene carbonate (FEC), were added to the bare electrolyte comprising 1 M LiTFSI in tetraethylene glycol di-Me ether/1,3 dioxolane in a ratio of 1:1 (volume/volume). The self-extinguishing time (SET) of the liquid electrolytes was measured. The 2032-type half-cells composed of Li/SiOx/Si/C were assembled, and their charge -discharge studies were analyzed at the 0.1 C-rate. Upon cycling, the electrode materials were subjected to surface morphol. and differential scanning calorimetry analyses. The interfacial properties of SiOx-based electrodes were investigated by electrochem. impedance spectroscopy, Fourier transform IR, and XPS studies. Among the electrolytes examined, FEC-added electrolytes offered the lowest SET and interfacial resistance values. The superior charge-discharge properties of FEC-added electrolytes were attributed to the formation of a stable solid electrolyte interface layer on the electrode surface. The surface chem. studies revealed the formation of Li2CO3 and ROCO2Li peaks on the electrode surface. In the experimental materials used by the author, we found Vinylene carbonate(cas: 872-36-6Electric Literature of C3H2O3)

In 2022,Wu, Li-Na; Wang, Zheng-Rong; Dai, Peng; Xie, Yu-Xiang; Hou, Cheng; Zheng, Wei-Chen; Han, Fa-Ming; Huang, Ling; Chen, Wei; Sun, Shi-Gang published an article in Chemical Science. The title of the article was 《A novel high-energy-density lithium-free anode dual-ion battery and in situ revealing the interface structure evolution》.Recommanded Product: 872-36-6 The author mentioned the following in the article:

Lithium-free anode dual-ion batteries have attracted extensive studies due to their simple configuration, reduced cost, high safety and enhanced energy d. For the first time, a novel Li-free DIB based on a carbon paper anode (Li-free CGDIB) is reported in this paper. Carbon paper anodes usually have limited application in DIBs due to their poor electrochem. performance. Herein, by using a lithium bis(fluorosulfonyl)imide (LiFSI)-containing electrolyte, the battery shows outstanding electrochem. performance with a capacity retention of 96% after 300 cycles at 2C with a stable 98% coulombic efficiency and 89% capacity retention after 500 cycles at 5C with a stable coulombic efficiency of 98.5%. Moreover, the electrochem. properties of the CGDIB were investigated with a variety of in situ characterization techniques, such as in situ EIS, XRD and online differential electrochem. mass spectrometry (OEMS). The multifunctional effect of the LiFSI additive on the electrochem. properties of the Li-free CGDIB was also systematically analyzed, including generating a LiF-rich interfacial film, prohibiting Li dendrite growth effectively and forming a defective structure of graphite layers. This design strategy and fundamental anal. show great potential and lay a theor. foundation for facilitating the further development of DIBs with high energy d.

《Porous Sb with three-dimensional Sb nanodendrites as electrode material for high-performance Li/Na-ion batteries》 was written by Meng, Weijia; Guo, Meiqing; Chen, Jiajun; Li, Diansen; Wang, Zhihua; Yang, Fuqian. Application In Synthesis of Vinylene carbonate And the article was included in Nanotechnology in 2020. The article conveys some information:

The increasing demand in energy consumption and the use of clean energy from sustainable energy sources have driven the research in the development of advanced materials for Li-ion and Na-ion batteries. In this work, we have developed a simple technique to synthesize a porous Sb structure through a galvanic replacement reaction between Sb3+ and Zn particles. The porous Sb structure consists of a three-dimensional-hierarchical structure with tree-like nanoscale Sb dendrites. The Sb in the nanodendrites is crystal of a rhombohedral structure. We construct Li-/Na-ion half cells and Li-/Na-ion full cells with the Sb nanodendrites as the active material in the working electrode and anode, resp., and introduce an additive of vinylene carbonate for the Li-ion half/full cells and an additive of fluoroethylene carbonate for the Na-ion half/full cells. All the Li-/Na-ion half cells and Li-/Na-ion full cells exhibit excellent electrochem. performance and cycling stability. Such excellent performance can be attributed to the synergistic interaction between the threedimensional- dendritic structure and electrolyte, which likely ensures fast transport of ions and electrons and the formation of a stable solid-state interphase. In the experiment, the researchers used many compounds, for example, Vinylene carbonate(cas: 872-36-6Application In Synthesis of Vinylene carbonate)

Transition-metal-catalyzed activation of inert C-H bonds and subsequent C-C bond formation have emerged as powerful synthetic tools for the synthesis of elaborate cyclic mols. In this report, an efficient synthetic method of 3,4-unsubstituted isocoumarins adopting an electron-deficient CpERh complex [CpE = 1,3-bis(ethoxycarbonyl)-2,4,5-trimethylcyclopentadienyl] as the catalyst is introduced. The use of vinylene carbonate as a vinylene transfer reagent enables the direct construction of isocoumarins I (R = H, 6-OMe, 8-OH, etc.) from readily available benzoic acids II, without any external oxidants as well as bases. The reaction mechanism is evaluated by computational anal. to find an unprecedented “”rhodium shift”” event within the catalytic cycle.

And the article was published in ACS Energy Letters in 2019. Synthetic Route of C3H2O3 The author mentioned the following in the article:

It is commonly believed that the formation of a solid-electrolyte interphase (SEI) is the main reason for improved electrode performance in rechargeable batteries. However, herein we present a new interfacial model that may change the thinking about the role of SEI, which has prevailed over the past 2 decades. We show that the varied desolvation behavior of mobile ions, which depends on the solvation structure determined by multiple factors (e.g., cations, solvent, anions, and additives) is a critical factor for electrode stability besides the SEI. This interfacial model can predict the intercalating species in graphite electrodes (i.e., Li+ (de)intercalation or Li+-solvent co-insertion) in different types of electrolytes (e.g., carbonate-, ether-based electrolyte). The generality of our model is further demonstrated by its ability to interpret the variable lithium plating/stripping in different electrolytes. Our model can predict electrode performance through the proposed cation-solvent interactions and desolvation behaviors and then help develop new types of electrolytes for mobile (ion) batteries. In the part of experimental materials, we found many familiar compounds, such as Vinylene carbonate(cas: 872-36-6Synthetic Route of C3H2O3)
