Title: Hyperbranched Poly(ethylene oxide) Electrolytes for Lithium Ion Batteries
Published: May 17, 2011
Abstract: This work demonstrates the capability of hyper-branched PEO polymers to act as a polyelectrolyte for Li-ion batteries. Hyperbranching has been shown to lead to a 100 fold increase in the ion conductivity below the melting temperature of the PEO crystallites. However, with high levels of incorporation of the glycidol comonomer (50%), there is a substantial drop in conductivity over the entire temperature range studied. The origins of this decrease in conductivity can be attributed to a suppression of the segmental dynamics of the hbPEO.
