Abstract

Described herein are materials for use in electrolytes that provide a number of desirable characteristics when implemented within batteries, such as high stability during battery cycling up to high temperatures, high voltages, high discharge capacity, high coulombic efficiency, and excellent retention of discharge capacity and coulombic efficiency over several cycles of charging and discharging. In some embodiments, a high voltage electrolyte includes a base electrolyte and a set of additive compounds, which impart these desirable performance characteristics.
