abstract = {The dynamics of lithium ions and polymer chains were
investigated at the molecular scale in the model polymer
electrolyte Poly (ethylene oxide) (PEO)/Lithium
bis(trifluoromethanesulfonyl)imide as a function of
temperature. This system is known to present an intermediate
range order from the arrangement of neighboring chain
segments as well as an extended range order of cylindrically
arranged chains. The collective dynamics of the systems at
lengthscales matching these structural features was measured
using Neutron Spin Echo spectroscopy, gaining insights into
their lifetime. Moreover, using isotope substitution
techniques the dynamics of the lithium ions with respect to
the other atoms was probed. The obtained results are
compared with the conductivity and the lithium
self-diffusion coefficient measured by NMR to gain
experimental insight on the molecular processes triggering
lithium transport.},
