Solid-state nmr study of new copolymers as solid polymer electrolytes

Abstract

We report the analysis of comb-like polymers by solid-state NMR. The polymers were previously evaluated as solid-polymer-electrolytes (SPE) for lithium-polymer-metal batteries that have suitable ionic conductivity at 60◦C. We propose to develop a correlation between13C solid-state NMR measurements and phase segregation.13C solid-state NMR is a perfect tool for differentiating polymer phases with fast or slow motions.7Li was used to monitor the motion of lithium ions in the polymer, and activation energies were calculated.
