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)
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.Electric Literature of C3H2O3
