ABSTRACT

Magnesium-ion systems are a promising alternative to their lithium-ion battery counterparts, providing an opportunity for low-cost, larger-scale capabilities in manufacturing, as well as a sustainable and safer alternative for energy storage. The characterization of the electrochemical nature of Magnesium bis (trifluoromethanesulfonimide) (Mg (TFSI)2) electrolyte system is investigated through the usage of electrochemical techniques to identify its morphological influence on electrode surfaces, reversibility, and kinetics. This electrochemical methodology (CE, CV, EIS, SEM) demonstrates electrolyte potential the magnesium ions. Incorporating preliminary data gathered from beaker cells establishes a base for a transition to coin cell data and analysis. Beaker cells detail a “three-electrode” system, isolating the behavior of the electrolyte for an understanding of the inherent properties of Mg (TFSI)2. However, coin cells provide an applied and symmetric “two-electrode” system that enacts electrolyte performance and battery conditions that more accurately represent real-world conditions working under limited volume and pressure.
