Silicon Electrolyte Interface Stabilization (SEISTa)

Coyle, Jaclyn; Zavadil, Kevin R.; Fenton, Kyle R.; McBrayer, Josefine D.; Apblett, Christopher A.

This quarter, we have focused on characterizing the electrochemical response, both through cyclic voltammetry and through constant current charge/discharge characterization of the silicon samples coated with silicates containing varying amounts of Li in the SiOx layer. These studies were performed using a standard Gen-2 electrolyte without FEC. We also performed electrochemical impedance spectroscopy on samples exposed to the Gen-2 electrolyte continually, and collected EIS spectra as a function of time and temperature.
