N2 - In pursuing advanced clean energy storage technologies, all-solid-state Li metal batteries (ASSMBs) emerge as promising alternatives to conventional organic liquid electrolyte-based batteries due to their reduced flammability risks, increased energy densities, extended lifespan, and design flexibility. Here, we estimate lithium requirements per unit of energy, cathode loading, and the amount of electrolyte required at a single-layer cell level ASSMB utilizing garnet-type, NASICON-type, and sulfide solid electrolytes and LiNi0.8Mn0.1Co0.1O2 (NMC811), LiCoO2, and LiFePO4 cathodes for Li metal anode and in situ anode configurations. To enable advanced batteries suitable for long-range and fast-charging electric vehicles, the electrodes (anode and cathode) must achieve a practical areal capacity of at least 7 mAh cm-2 and support rapid charging rates of 4C (15 min). Furthermore, we also present the key requirements for mechanical properties and strategic design considerations in ASSMB architecture to effectively address the challenges posed by the volume expansion of the electrodes.
