      abstract     = {Pure LiFePO4 (LFP) thin films with different thicknesses
                      are deposited at room temperature by a radio frequency (RF)
                      magnetron-sputtering process. Ti foils with and without
                      titanium nitride (TiN) coating as well as thermally oxidized
                      Si wafers coated with Ti or TiN are used as substrates. In a
                      subsequent annealing step, LiFePO4 thin films are
                      crystallized at 500 °C. The interaction between Ti and
                      LiFePO4 as well as between TiN and LiFePO4 is characterized
                      by means of X-ray diffraction (XRD), scanning electron
                      microscope (SEM), energy dispersive X-ray analysis (EDX),
                      secondary ion mass spectrometry (SIMS), cyclic voltammetry
                      (CV) and galvanostatic measurements. A severe diffusion of
                      Ti into LiFePO4 is found and leading to the formation of
                      impurity phases which resulting in disturbing
                      crystallization behaviour and rough surfaces. Moreover, 80
                      nm LiFePO4 thin films do not show the desired
                      electrochemical characteristics when they are deposited on
                      Ti foils directly. By using a TiN interlayer, the diffusion
                      of Ti into LiFePO4 can be blocked resulting in smooth
                      morphologies and improving crystallisation behaviour.
                      Impurity phases do not develop and all samples exhibit the
                      expected electrochemical characteristics. Therefore, TiN is
                      a promising candidate for the use as a current collector in
                      all-solid-state batteries with LiFePO4 electrodes.},
