Title: High efficiency electrolytes for high voltage battery systems

Abstract

Disclosed herein are embodiments of an electrolyte that is stable and efficient at high voltages. The electrolyte can be used in combination with certain cathodes that exhibit poor activity at such high voltages with other types of electrolytes and can further be used in combination with a variety of anodes. In some embodiments, the electrolyte can be used in battery systems comprising a lithium cobalt oxide cathode and lithium metal anodes, silicon anodes, silicon/graphite composite anodes, graphite anodes, and the like.
