      abstract     = {Polymer films based on poly(vinylidene
                      difluoride-co-hexafluoropropylene) (P(VdF-HFP)) with
                      different amounts of bis(trifluoromethane)sulfonimide
                      lithium salt (LiTfSI) were prepared from acetone solution in
                      a doctor blade casting machine under controlled and
                      reproducible drying conditions.The modification of the
                      copolymer-based layers show a significant enhancement of
                      conductivity over several orders of magnitude for increasing
                      LiTfSI content and a constantly low electronic conductivity.
                      The addition of salt results in a structural change of the
                      crystalline areas in the semi-crystalline copolymer matrix
                      from α- to γ-phase of P(VdF), which has been studied using
                      Raman spectroscopy and X-Ray diffraction. Lithium ions are
                      coordinated by oxygen atoms of TfSI− as verified by Raman
                      spectroscopy and molecular dynamics simulations. Based on
                      the experimental data and simulation results, we propose a
                      transport mechanism for the lithium ions through salt
                      channels in the amorphous regions of the non-coordinating
                      copolymer matrix via hopping between stabilized positions.},
