Ion Coordination in Polymer Electrolytes from REDOR NMR Studies Poly (ethylene oxide) (PEO) was first used as a potential solid polymer electrolyte material in 1975. Although this material has been extensively studied over the past 30 years, commercial batteries based on PEO electrolytes have not yet materialized. Hampering progress is a lack of understanding about molecular structure around the lithium ion. This structural information can be provided by solid state NMR and REDOR. We have been able to show that the lithium environment in a sample 20:1 PEO: LiTf complex is similar to the lithium in a 3:1 complex. Additional variable-temperature measurements of structure and dynamics demonstrate the wealth of information solid state NMR provides for polymer electrolytes. |
