Anode-free all-solid-state lithium-ion batteries (ASSBs) are among the most promising energy storage devices owing to their high density and safety. Protective layers, such as Ag-C composite layer, essential for suppressing unwanted reactions between electrodeposited Li metal solid-state electrolyte, thereby ensuring highly cyclable ASSBs. Although recent research efforts have focused on composition microstructure of carbon-based protective there a few reports relationship layers cycling performance ASSBs, particularly when pore size carbon is within criterion Coble creep. Herein, we demonstrate that stability anode-free ASSBs with metal-free layer can be affected by electrical conductivity powders especially surface morphologies volume. Among exhibited relatively capacity retention, smallest volume highest retention (78.8% initial capacity) after 300 cycles, probably because large fraction lithiated particles, which could act Li-ion conducting media enable uniform plating. These results reveal significance microstructural engineering long-term
