    摘要: An anode-less all-solid-state battery includes a porous layer that is able to occlude and release lithium, rather than a typical composite anode including an anode active material, thereby greatly improving the energy density thereof. The all-solid-state battery includes an anode current collector layer, a porous layer provided on at least one surface of the anode current collector layer and configured to include a three-dimensionally interconnected framework so as to form pores therein, a solid electrolyte layer provided on the porous layer, and a composite cathode layer provided on the solid electrolyte layer, in which a seed material is provided at an interface between the anode current collector layer and the porous layer and at an interface between the porous layer and the solid electrolyte layer.
