Abstract
An anode-solid electrolyte sub-assembly including an anode and a solid electrolyte, wherein the anode includes an anode current collector, a first anode active material layer disposed adjacent to the solid electrolyte and including a first anode active material, and a carbon-based material-containing layer disposed between the first anode active material layer and the anode current collector and containing a porous carbon structure, a porosity of the carbon-based material-containing layer is greater than a porosity of the first anode active material layer, and an average pore size of the porous carbon structure in the carbon-based material-containing layer is greater than an average pore size of the first anode active material in the first anode active material layer or an average pore size of the carbon-containing layer is greater than an average pore size of the first anode active material layer.
