The dielec. constant is a crucial physicochem. property of liquids in tuning solute-solvent interactions and solvation microstructures. Herein the dielec. constant variation of liquid electrolytes regarding to temperatures and electrolyte compositions is probed by mol. dynamics simulations. Dielec. constants of solvents reduce as temperatures increase due to accelerated mobility of mols. For solvent mixtures with different mixing ratios, their dielec. constants either follow a linear superposition rule or satisfy a polynomial function, depending on weak or strong intermol. interactions. Dielec. constants of electrolytes exhibit a volcano trend with increasing salt concentrations, which can be attributed to dielec. contributions from salts and formation of solvation structures. This work affords an at. insight into the dielec. constant variation and its chem. origin, which can deepen the fundamental understanding of solution chem. The experimental part of the paper was very detailed, including the reaction process of Vinylene carbonate(cas: 872-36-6Recommanded Product: 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.Recommanded Product: 872-36-6
