Preparation and Characterization of PEO Functionalized Silsequixanes as Nanofunctional Materials for Lithium Batteries

摘要

Polyethylene oxide (PEO) has been proposed as a material for use in solid state lithium batteries due to its ability to solvate lithium ions.However,the semicrystalline nature of high molecular weight PEO makes its room temperature ionic conductivity,a,low.In order to increase a,several approaches have been attempted,namely,by crosslinking reactions,co-polymerization,addition of nano-size fillers and by attachment of short chain PEO oligomers as side chains to form "comb-shaped" or "hairy-rod" like structures on other polymers or as "arms" from inorganic scaffolds.
