Polymer electrolytes have potential for use in next generation lithium and sodium batteries.Replacing the liquid electrolyte currently used has several advantages: it allows use of high energy density solid lithium as the anode,removes toxic solvents,improves safety,and eliminates the need for heavy casings.Despite their advantages,the conductivity of solid polymer electrolytes is not sufficient for use in batteries.As a result,considerable effort towards improving conductivity and understanding mechanisms of lithium transport has taken place over the last 30 years.This talk considers the interplay of conductivity,crystallinity,local coordination and polymer dynamics in solid polymer electrolytes.Using a combination of experimental and computational technique,we propose the possibility of high charge mobility using ion aggregates and percolated nanofiller networks.
