Nonaqueous multivalent systems are competitive as future lithium-ion battery (LIB) replacements to address growing energy storage needs. High volumetric specific capacity, low cost, long lifetime, are some driving advantages of these systems. Their development has been slowed by a plethora of fundamental unknowns. Mechanisms of multivalent charge transfer are complicated and not well understood in detail. Strategic electrochemical investigation into fundamental redox mechanisms and kinetics of multi-charge transfer of Magnesium and Zinc nonaqueous electrolytes will be presented here. Influence of solvent system, concentration, anion identity, and solvent structure are investigated as each has an integral role.
