Abstract: A three-dimensional (“3D”) electrode structure includes a current collecting layer, a plurality of plates including an active material and disposed on the current collecting layer, and a plurality of inner support layers disposed between the plurality of plates. The plurality of plates includes first, second, and third plates. An inner support layer of the inner support layers is disposed between the first and second plates, and another inner support layer of the inner support layers is disposed between the second and third plates. The inner support layer between the first and second plates and the another inner support layer between the second and third plates are arranged at different positions in a lengthwise direction of the second plate.

Abstract: A secondary battery having a three-dimensional (“3D”) structure with a curvature and a method of manufacturing the same are provided. The secondary battery includes a 3D electrode structure, and a first collector layer and a second collector layer, which are disposed on the 3D electrode structure. The 3D electrode structure is curved in a thickness direction thereof to have a curvature, and the first collector layer and the second collector layer have a curvature corresponding to the curvature of the 3D electrode structure.
