      abstract     = {High-pressure field assisted sintering (FAST/SPS) of
                      half-cell for all-solid-state Li batteries was proposed and
                      tested. The half-cell included the layer of lithium
                      lanthanum zirconate (LLZO) electrolyte and the layer of
                      mixed cathode. The mixed cathode consisted of lithium cobalt
                      oxide (LCO) used as energy storage material and LLZO used as
                      ionic conductor. A tool made of TZM molybdenum alloy was
                      used to apply a high pressure of 440 MPa during FAST/SPS
                      at a temperature of 675 °C ensuring stability of
                      materials. An average relative density of sintered half-cell
                      was around of $95\%.$ The half-cell was assembled with a
                      lithium anode and electrochemically tested. The results were
                      compared with the performance of a half-cell sintered in an
                      established graphite tool at the same temperature but under
                      a lower pressure of 50 MPa and with a lower density
                      (around of $78\%).$ The battery with half-cell sintered at
                      high pressure showed two-fold larger surface storage
                      capacity. Further optimization of materials and processing
                      is in progress.},
