Reaction energies were determined for reductive ring-opening reactions of Li-coordinated ethylene carbonate (EC) and vinylene carbonate (VC) by a density functional method. We have also explored the ring-opening of Li-EC and Li-VC by reaction with a nucleophile (CHO.) thermodynamically. Our ther...
Li–O2 batteries have received considerable attention owing to their high theoretical gravimetric energy densities. However, the sluggish kinetic barrier between gaseous O2 and solid products leads to severe polarized overpotenial. Besides, the gas-open
45Some additives in the electrolyte can decompose and precipitate on the anode at a higher voltage. For example, vinylene carbonate (VC) has lower activation energy for reduction
In Situ Generation of Poly (Vinylene Carbonate) Based Solid Electrolyte with Interfacial Stability for LiCoO2 Lithium Batteries electrolyte that possesses both interfacial stability toward lithium/graphitic anodes and high voltage cathodes for high energy density solid state batteries. Ins... J Chai,Z Li...
added to a large-capacity battery composed of a high-Ni anodes and a Si-mixed anode, the initial capacity was maintained at 81.5% even after 400 charging and discharging cycles—10% to 30% better than the choice of VC (vinylene carbonate) or FEC (fluoroethylene carbonate), asadditivein ...
-forming additives, 5-methyl-4-((trifluoromethoxy)methyl)-1,3-dioxol-2-one and 5-methyl-4-((trimethylsilyloxy)methyl)-1,3-dioxol-2-one, provide spatial flexibility to the vinylene carbonate-derived solid electrolyte interphase via polymeric propagation with the vinyl group of vinylene carbonate....
