      abstract     = {All-solid-state Li batteries (ASSLBs) are regarded as the
                      systems of choice for future electrochemical energy storage.
                      Particularly, the garnet Li7La3Zr2O12 (LLZO) is one of the
                      most promising solid electrolytes due to its stability
                      against Li metal. However, its integration into ASSLBs is
                      challenging due to high temperature and long dwell time
                      required for sintering. Advanced sintering techniques, such
                      as Ultrafast High-temperature Sintering, have shown to
                      significantly increase the sintering rate. Direct contact to
                      graphite heaters allows sintering of LLZO within 10 s due to
                      extremely high heating rates (up to 104 K min−1) and
                      temperatures up to 1500 °C to a density around 80 $\%.$ The
                      LLZO sintered in vacuum and Ar atmosphere has good
                      mechanical stability and high phase purity, but kinetic
                      de-mixing at the grain boundaries was observed.
                      Nevertheless, the Li-ion conductivity of 1 mS cm−1 at 80
                      °C was comparable to conventional sintering, but lower than
                      for Field-Assisted Sintering Technique/Spark Plasma
                      Sintering.},
