Multivalent batteries, such as rechargeable Mg-ion batteries, may be able to overcome the safety and cost limitations of Li-ion batteries. They are promising candidates for applications in large-scale stationary energy storage as well as in transportation. Finding high-voltage electrolytes which are compatible with the Mg-ion battery chemistry continues to be a research focus. In this work, we present electrochemical analysis of a a fluorinated dialkoxide-based magnesium-ion electrolyte. The electrolyte is stable at high voltages (>2V) and shows good performance in full battery cells using Chevrel phase Mo6S8. Its performance in other sulfide-based cathodes is also reported.
