AI Technical Summary
Existing polymer electrolyte membranes in lithium batteries suffer from insufficient ionic conductivity and poor interfacial contact, which limits battery performance. Furthermore, zero-dimensional nanofillers tend to agglomerate in the polymer matrix, hindering ion transport.
A composite electrolyte membrane with a fast ion transport channel was prepared by using an inclusion complex of sulfobutyl-β-cyclodextrin and hydrophobic lithium-ion battery electrolyte solution as a filler and forming an ordered arrangement in the polymer precursor solution by applying an alternating electric field.
It improves the ionic conductivity of lithium-ion batteries, forms continuous and rapid ion transport channels, suppresses lithium dendrite growth, and enhances battery safety and performance.
