      abstract     = {Solid-state batteries (SSBs) are a promising technology for
                      high travelling ranges and safety in future electromobility.
                      In SSBs, separator and liquid electrolyte materials are
                      combined in a solid-state electrolyte layer. Possible
                      materials for SSBs are ceramic oxides, for example LiCoO2
                      (LCO) as cathode material and Li7La3Zr2O12 (LLZO) as
                      electrolyte material. By means of screen printing, a mixed
                      cathode material (mixture of cathode and electrolyte
                      material to have higher ionic conductivity in the cathode)
                      is applied on a stainless steel current collector foil and
                      after thermal processing, the electrolyte material is
                      printed on top of the sintered mixed cathode to create a
                      half-cell. Both layers are thermally post treated (dried and
                      sintered) in consecutive steps to produce functional layers
                      for SSBs. Conventional heat treatment is done in an oven
                      process. A main disadvantage is the diffusion of materials
                      into adjacent layers due to long process times (range of
                      minutes) at high temperatures. Furthermore, the battery
                      half-cell cannot be treated at high temperatures due to
                      incompatibilities in decomposition temperatures of LLZO and
                      LCO. Preservation of the crystal structure and a suitable
                      temperature management during the sintering process are of
                      enormous importance. By means of laser processing, short
                      interaction times (range of seconds and below) are realized.
                      High heating rates show potential for reducing diffusion
                      processes and preserving the crystal structure of the
                      materials. In this work, the influence of different
                      interaction times on crystal structure and adhesion are
                      investigated for laser sintering of LLZO and LCO micro
                      particle layers.},
