《Exploring the Role of Vinylene Carbonate in the Passivation and Capacity Retention of Cu2Sb Thin Film Anodes》 was written by Kraynak, Leslie A.; Schneider, Jacob D.; Prieto, Amy L.. Reference of Vinylene carbonateThis research focused onvinylene carbonate copper antimonide anode passivation capacity retention; lithium ion battery electrode vinylene carbonate passivation capacity retention. The article conveys some information:
Electrolyte additives such as vinylene carbonate (VC) have been demonstrated to improve the capacity retention for many types of Li-ion battery electrodes, including intermetallic alloying anodes, but it is still unclear why VC extends the cycle lifetime of copper antimonide (Cu2Sb) anodes so dramatically. Here, we have studied how VC affects the solid electrolyte interface formed on Cu2Sb thin film anodes in fluorine-free electrolyte solutions in order to better understand which nonfluorinated species may play an important role in effective Cu2Sb passivation. Using differential capacity anal. and XPS, it was found that VC effectively passivates Cu2Sb and prevents Cu/Cu2Sb oxidation at high potentials. Carbonate species from the reduction of VC seem to play an important role in passivation, while inorganic species like LiClO4 from the F-free supporting electrolyte do not seem to be beneficial. In addition to this study using Vinylene carbonate, there are many other studies that have used Vinylene carbonate(cas: 872-36-6Reference of Vinylene carbonate) was used in this study.
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
