      abstract     = {All‐solid‐state batteries using garnet‐type solid
                      electrolyte are considered as a promising solution for the
                      next generation energy storage systems but to date they
                      still suffer from low ionic conductivity compared to organic
                      liquid electrolytes and poor interfacial contact between the
                      electroactive materials and the electrolyte. Here we propose
                      several proof‐of‐concept level strategies to enhance the
                      interfacial contact between the electroactive material Sn
                      and the solid electrolyte Ta‐LLZO doped (hereafter called
                      LLZTa) to enable proper electrochemical cycling. First, we
                      demonstrate that the conventional slurry‐based technique
                      is not appropriate to ensure cycling of a Sn based electrode
                      in all‐solid‐state batteries due to poor interfacial
                      contact. Then, we demonstrate (proof‐of‐concept) that
                      thin films deposition is a more suitable approach to ensure
                      electrochemical activity but the large volume changes of Sn
                      during alloying process is leading to a rapid cell failure.
                      This last challenge was overcome by the use of a chemically
                      pre‐lithiated Sn thin film which then delivers, after an
                      activation process, specific charge close to the theoretical
                      one (900 mAh/g) at C/30 rate and T =80 °C.},
