      abstract     = {To address the manifold challenges solid electrolytes (SE)
                      do face in NMC‖Lithium metal batteries, we demonstrate
                      that these can be overcome by converting a commercial
                      Celgard 2500 separator into a jack of all trades hybrid
                      solid electrolyte (HSE). This approach follows a multi-layer
                      electrolyte strategy, to better cope with the very different
                      chemistries of the cathode, the bulk electrolyte material,
                      and the Li metal anode. A cathode-facing electrolyte layer
                      based on lithium aluminum titanium phosphate (LATP) provides
                      a high voltage stability of ≥4.5 V. High mechanical
                      strength of the overall thin film electrolyte (≤50 μm)
                      is achieved with a middle layer based on Celgard 2500. The
                      layer on the anode side, based on polyethylene oxide (PEO),
                      allows stable cycling of the lithium metal. High Coulombic
                      efficiencies in NMC622‖Li metal cells $(99.9 \%)$ and
                      LFP‖Li metal cells $(99.9 \%)$ enable long term cycling
                      with high-capacity retention of $46 \%$ and $52 \%$
                      after 1,000 cycles, respectively.},
