Abstract
Official abstract text for this publication.
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 temperature electrolyte includes a base electrolyte and one or more polymer additives, which impart these desirable performance characteristics.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid electrolyte formulation, comprising: a lithium salt, a non-aqueous solvent, and a polymer additive present at less than 10% by weight of the total weight of the liquid electrolyte formulation and represented by Formula (b): where n is an integer greater than 1 and R 1 is an alkyl group or a substituted alkyl group and wherein the polymer additive is a homopolymer. 2. The liquid electrolyte formulation of claim 1 , wherein the polymer additive is represented by Formula (a): 3. The liquid electrolyte formulation of claim 1 , wherein the weight average molecular weight of the polymer additive is less than or equal to 500,000 g/mol. 4. The liquid electrolyte formulation of claim 1 , wherein the polymer additive is present at a concentration of at least 0.1 weight percent of the total weight of the liquid electrolyte formulation. 5. The liquid electrolyte formulation of claim 1 , wherein the polymer additive is present at a concentration of at least 0.5 weight percent of the total weight of the liquid electrolyte formulation.
