A Linear Sweep Voltametry Study of High-Concentration Electrolytes

Dilute, industry-standard electrolytes perform well under ideal conditions and low voltage. However, with the demand for high power batteries for electric vehicles (EVs) and handheld devices, novel electrochemistry is needed to provide a liquid electrolyte that can shuttle ions safely at high voltage. Higher salt concentration is one potential answer. In this project we used Linear Sweep Voltametry (LSV) to study the effect of increasing the concentration of NaCl in solution in water as a model electrolyte system. Greater voltage stability, with less faradic current, was observed at higher concentrations.
