Langdon, Jayse; Cui, Zehao; Manthiram, Arumugam published an article in 2021. The article was titled 《Role of Electrolyte in Overcoming the Challenges of LiNiO2 Cathode in Lithium Batteries》, and you may find the article in ACS Energy Letters.Product Details of 872-36-6 The information in the text is summarized as follows:

LiNiO2 (LNO) is a high-capacity and model cathode first discovered in the 1980s that fell out of favor due to its intrinsic instabilities. However, research activities toward LNO are once again on the rise as the push for higher-energy-d. cells marches on. We demonstrate here that with appropriate modern electrolytes, major performance improvements can be achieved with LNO with no addnl. modifications. Cells with a localized high concentration electrolyte (LHCE) deliver 92% capacity retention after 200 cycles compared with 56% capacity retention in a baseline carbonate electrolyte, maintain 94% capacity after high-voltage storage compared with 77% capacity, and display a higher onset temperature of thermal runaway of 244°C compared with 188°C. These improvements are attributed to the LHCE’s high oxidative stability and its formation of fluorine-rich interphases. Although further characterization of this new class of electrolyte is necessary, this work demonstrates that modern electrolytes can be drop-in enablers of high-capacity, long-cycle-life cells.

And the article was published in Scientific Reports in 2019. SDS of cas: 872-36-6 The author mentioned the following in the article:

Data-driven material discovery has recently become popular in the field of next-generation secondary batteries. However, it is important to obtain large, high quality data sets to apply data-driven methods such as evolutionary algorithms or Bayesian optimization. Combinatorial high-throughput techniques are an effective approach to obtaining large data sets together with reliable quality. In the present study, we developed a combinatorial high-throughput system (HTS) with a throughput of 400 samples/day. The aim was to identify suitable combinations of additives to improve the performance of lithium metal electrodes for use in lithium batteries. Based on the high-throughput screening of 2002 samples, a specific combination of five additives was selected that drastically improved the coulombic efficiency (CE) of a lithium metal electrode. Importantly, the CE was remarkably decreased merely by removing one of these components, highlighting the synergistic basis of this mixture The results of this study show that the HTS presented herein is a viable means of accelerating the discovery of ideal yet complex electrolytes with multiple components that are very difficult to identify via conventional bottom-up approach. In the part of experimental materials, we found many familiar compounds, such as Vinylene carbonate(cas: 872-36-6SDS of cas: 872-36-6)

And the article was published in Journal of Power Sources in 2019. Reference of Vinylene carbonate The author mentioned the following in the article:

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.

The title of the article was 《Hollow-core optical fibre sensors for operando Raman spectroscopy investigation of Li-ion battery liquid electrolytes》.Computed Properties of C3H2O3 The author mentioned the following in the article:

Improved anal. tools are urgently required to identify degradation and failure mechanisms in Li-ion batteries. However, understanding and ultimately avoiding these detrimental mechanisms requires continuous tracking of complex electrochem. processes in different battery components. Here, we report an operando spectroscopy method that enables monitoring the chem. of a carbonate-based liquid electrolyte during electrochem. cycling in Li-ion batteries with a graphite anode and a LiNi0.8Mn0.1Co0.1O2 cathode. By embedding a hollow-core optical fiber probe inside a lab-scale pouch cell, we demonstrate the effective evolution of the liquid electrolyte species by background-free Raman spectroscopy. The anal. of the spectroscopy measurements reveals changes in the ratio of carbonate solvents and electrolyte additives as a function of the cell voltage and show the potential to track the lithium-ion solvation dynamics. The proposed operando methodol. contributes to understanding better the current Li-ion battery limitations and paves the way for studies of the degradation mechanisms in different electrochem. energy storage systems.

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.

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.

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)

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.

《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.
