Electrochem. quartz crystal microbalance (EQCM) with damping monitoring is applied for real-time anal. of solid-electrolyte interphase (SEI) formation in di-Ph octyl phosphate (DPOP) and vinylene carbonate (VC) modified electrolytes. Fast SEI formation is observed for the DPOP containing electrolyte, whereas slow growth is detected in VC-modified and reference electrolytes. QCM measurements in a dry state show considerable reduction of the mass quantity for DPOP and reference samples and minor mass decrease for the SEI layer formed in the presence of VC. VC enhances SEI stability, whereas the addition of DPOP or no additive results in incorporation of loosely attached species, leading to SEI instability. Resonance frequency damping, Δw, and dissipation factor, D, were used for analyzing mech. properties of the SEI layers. The apparent increase of Δw and D during SEI formation in presence of DPOP suggests a pronounced viscoelasticity of the layer. QCM results are compared with surface morphol. and chem. composition, revealing excellent agreement of the applied characterization approaches. In the experimental materials used by the author, we found 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
