Abstract: Disclosed is an anode-free all-solid-state battery having improved charge/discharge cycle stability. Specifically, the anode-free all-solid-state battery includes a cathode layer containing a cathode active material, an anode current collector layer, and a solid electrolyte layer interposed between the cathode layer and the anode current collector layer, wherein the anode current collector layer has a surface roughness (Rq) of 100 nm to 1,000 nm.
