Abstract
Described herein are additives for use in electrolytes that provide a number of desirable characteristics when implemented within batteries, such as high capacity retention during battery cycling at high temperatures. In some embodiments, a high voltage electrolyte includes a base electrolyte and one or more vinylsilane or fluorosilane additives, which impart these desirable performance characteristics.
