Abstract

The lithium cation environments need to be characterized as accurately as possible, particularly in the microseparated phases of polyether polyurethane urea (PEUU) electrolytes, since it is the source that supplies the high ionic conductivity. The Li+ magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectra with high-power proton decoupling provides an extremely effective and unique method for probing different local environments of lithium cations in PEUU-based electrolytes. The method allows the properties of each of the different lithium cations to be observed directly and with high spectral resolution.
