Omale, Joel O.; Van Velthem, Pascal; Antohe, Vlad-Andrei; Vlad, Alexandru; Piraux, Luc published an article in 2021. The article was titled 《Effects of Electrolyte Additives and Nanowire Diameter on the Electrochemical Performance of Lithium-Ion Battery Anodes based on Interconnected Nickel-Tin Nanowire Networks》, and you may find the article in Energy Technology (Weinheim, Germany).HPLC of Formula: 872-36-6 The information in the text is summarized as follows:
Tin-based nanowire electrodes present desirable properties as lithium-ion battery anodes, because they undergo volume changes without pulverization. However, they suffer from limited mass loading and propensity for surface parasitic reactions. Herein, the electrochem. performances of nickel-tin 3D-interconnected nanowire network (NiSn 3DNWN) electrodes are evaluated with the nanowire diameters of 40, 105, and 230 nm, resp., that attain mass loadings of up to 3 mg cm-2. To mitigate the surface parasitic reactions, the effects of fluoroethylene carbonate (FEC) and vinylene carbonate (VC) additives are investigated as a function of the nanowire diameter and additive concentration The results show that the FEC and VC of all compositions improve the capacity retentions and coulombic efficiencies (CEs) of the NiSn 3DNWN electrodes. In 10 vol% FEC, the electrodes demonstrate a similar capacity of ≈550 mAh g-1, but the capacity retentions after 100 cycles are 73.68%, 53.79%, and 51.70% for the 40, 105, and 230 nm NiSn 3DNWN, resp. However, the 105 nm-diameter nanowire electrode has the highest average CE of 96.55%. Electrochem. impedance spectroscopy and post-cycling investigations reveal that the FEC has the most profound effect on the interfacial resistances, which is reflected in the rate performances of the tested electrodes. The experimental part of the paper was very detailed, including the reaction process of Vinylene carbonate(cas: 872-36-6HPLC of Formula: 872-36-6)
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.HPLC of Formula: 872-36-6
