Abstract
Complementary NMR studies on PPOn(LiTFSI) polymer electrolytes are rep orted. An improved sequence for measuring the diffusion constants of p roton and lithium nuclei is presented, allowing the determination of t he transport number of these systems. Our descriptive model, involving the coexistence of entangled and non-entangled parts of the high weig ht polymer chains, is supported by the various results concerning the relaxation times and the H-1 diffusion constants.
