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 polymer additives, which impart these desirable performance characteristics. The polymer additives can be homopolymers or copolymers.
