      abstract     = {The development of high-capacity, high-performance
                      all-solid-state batteries requires the specific design and
                      optimization of its components, especially on the positive
                      electrode side. For the first time, we were able to produce
                      a completely inorganic mixed positive electrode consisting
                      only of LiCoO2 and Ta-substituted Li7La3Zr2O12 (LLZ:Ta)
                      without the use of additional sintering aids or conducting
                      additives, which has a high theoretical capacity density of
                      1 mAh/cm2. A true all-solid-state cell composed of a Li
                      metal negative electrode, a LLZ:Ta garnet electrolyte, and a
                      25 μm thick LLZ:Ta + LiCoO2 mixed positive electrode was
                      manufactured and characterized. The cell shows $81\%$
                      utilization of theoretical capacity upon discharging at
                      elevated temperatures and rather high discharge rates of 0.1
                      mA (0.1 C). However, even though the room temperature
                      performance is also among the highest reported so far for
                      similar cells, it still falls far short of the theoretical
                      values. Therefore, a 3D reconstruction of the manufactured
                      mixed positive electrode was used for the first time as
                      input for microstructure-resolved continuum simulations. The
                      simulations are able to reproduce the electrochemical
                      behavior at elevated temperature favorably, however fail
                      completely to predict the performance loss at room
                      temperature. Extensive parameter studies were performed to
                      identify the limiting processes, and as a result, interface
                      phenomena occurring at the cathode active
                      material/solid–electrolyte interface were found to be the
                      most probable cause for the low performance at room
                      temperature. Furthermore, the simulations are used for a
                      sound estimation of the optimization potential that can be
                      realized with this type of cell, which provides important
                      guidelines for future oxide based all-solid-state battery
                      research and fabrication.},
