ELECTROLYTE CHEMICAL FORMULATIONS FOR ENERGY STORAGE DEVICES

The present invention discloses ionically conducting electrolytes that include a liquefied gas solvent displaying low global warming potential (GWP) and low flammability while also generating favorable solid-electrolyte interphases in an electrochemical device to maintain high performance and cycle life. Ionically conducting electrolytes include a multi-component solvent mixture with a low-GWP solvent and non-low GWP solvent. The overall GWP of the multi-component solvent mixture is at least 50% less than the GWP of the non-low GWP solvent alone.
