      abstract     = {High interfacial resistance between solid electrolyte and
                      electrode of ceramic all-solid-state batteries is a major
                      reason for the reduced performance of these batteries. A
                      solid-state battery using a monolithic all-phosphate concept
                      based on screen printed thick LiTi2(PO4)3 anode and
                      Li3V2(PO4)3 cathode composite layers on a densely sintered
                      Li1.3Al0.3Ti1.7(PO4)3 solid electrolyte has been realized
                      with competitive cycling performance. The choice of
                      materials was primarily based on the (electro-)chemical and
                      mechanical matching of the components instead of solely
                      focusing on high-performance of individual components. Thus,
                      the battery utilized a phosphate backbone in combination
                      with tailored morphology of the electrode materials to
                      ensure good interfacial matching for a durable mechanical
                      stability. Moreover, the operating voltage range of the
                      active materials matches with the intrinsic electrochemical
                      window of the electrolyte which resulted in high
                      electrochemical stability. A highly competitive discharge
                      capacity of 63.5 mAh g–1 at 0.39 C after 500 cycles,
                      corresponding to $84\%$ of the initial discharge capacity,
                      was achieved. The analysis of interfacial charge transfer
                      kinetics confirmed the structural and electrical properties
                      of the electrodes and their interfaces with the electrolyte,
                      as evidenced by the excellent cycling performance of the
                      all-phosphate solid-state battery. These interfaces have
                      been studied via impedance analysis with subsequent
                      distribution of relaxation times analysis. Moreover, the
                      prepared solid-state battery could be processed and operated
                      in air atmosphere owing to the low oxygen sensitivity of the
                      phosphate materials. The analysis of electrolyte/electrode
                      interfaces after cycling demonstrates that the interfaces
                      remained stable during cycling.},
