Abstract: A secondary battery may include a plurality of cathode layers which have a porous structure including a plurality of pores, have a flat plate-shape, and are arranged to be spaced apart from each other in a direction. The secondary battery further includes an electrolyte layer including a first electrolyte film and a second electrolyte film, where the first electrolyte film surrounds external surfaces of the cathode layers, and the second electrolyte film is disposed in the pores of the cathode layers. The secondary battery further includes an anode layer surrounding the first electrolyte film.

Abstract: A three-dimensional (“3D”) electrode structure includes a current collecting layer, a plurality of plates protruding from the current collecting layer and including an active material, and a base layer provided between the current collecting layer and the plurality of plates. The base layer includes an active material-metal sintered composite. The plurality of plates includes an active material-metal sintered composite. A metal content of the active material-metal sintered composite of the plurality of plates is less than a metal content of the active material-metal sintered composite of the base layer. At least one partition wall supporting the plurality of plates is further provided on the base layer.
