      abstract     = {In order to favor electronic conductivity in sodium iron
                      fluorophosphate electrodes for lithium- or sodium-ion
                      batteries, composites of Na2FePO4F with multi-walled carbon
                      nanotubes (CNTs) were prepared by pilot-scale spray drying.
                      Addition of multi-walled CNTs in the solution results in an
                      excellent dispersion of the CNTs within the volume of
                      Na2FePO4F and not only at the surface of the particles.
                      Following a heat treatment at 600 °C in argon in order to
                      reach crystallization, X-ray diffraction and ex situ
                      Mössbauer spectroscopy revealed the presence of significant
                      amounts of Fe(III) and maghemite (γ-Fe2O3) in the powder.
                      However, Na2FePO4F/CNTs composites exhibit good
                      electrochemical performance when cycling against lithium,
                      with a discharge capacity of 104 mA h g−1 at C/10 rate and
                      90 mA h g−1 at 1C rate. Therefore, operando57Fe
                      transmission Mössbauer spectroscopy analyses were carried
                      out in order to investigate the evolution of the iron
                      oxidation state during cycling. During the first discharge,
                      all the Fe(III) is reduced to Fe(II), explaining the good
                      electrochemical performance.},
