MATERIALS FOR BATTERY ELECTROLYTES AND METHODS FOR USE

摘要

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. A high voltage electrolyte includes a base electrolyte and an additive compound. The additive compound includes a silicon-containing anion and a metal ion.
