| Zusammenfassung: | © 2021 Wiley-VCH GmbH. The energy density presents the core competitiveness of lithium (Li)-ion batteries. In conventional Li-ion batteries, the utilization of the gravimetric/volumetric energy density at the electrode level is unsatisfactory (<84 wt% and <62 vol%, respectively) due to the existence of non-electrochemical active parts among the 3D porous electrodes, including electrolytes, binders, and carbon additives. These are regarded as indispensable and irreducible components of the electronic and ionic transport network. Here, a dense "all-electrochem-active" (AEA) electrode for all-solid-state Li batteries is proposed, which is entirely constructed from a family of superior mixed electronic-ionic-conducting cathodes, to minimize the energy density gap between the accessible and theoretical energy density at the electrode level. Furthermore, with the ionic-electronic-conductive network self-supported from the AEA cathode, the dense hybrid sulfur (S)-based AEA electrode exhibits a high compacted filling rate of 91.8%, which indicates a high energy density of 777 W h kg-1 and 1945 W h L-1 at the electrode level based on the total cathodes and anodes when at 70 °C |
