Abstract
An electrode structure, a bipolar all-solid secondary battery including the same, and a method of manufacturing the electrode structure are provided. The electrode structure includes: a current collector having a first surface and a second surface, wherein the first surface includes a first portion, a second portion, and an intermediate portion between the first portion and the second portion, the first portion and the second portion are arranged toward the outside in opposite directions to each other around the intermediate portion, and the second surface has an inward-folded structure; a cathode active material layer formed on the first portion of the first surface; an anode active material layer formed on the second portion of the first surface; and a compression pad arranged inside the inward-folded structure of the current collector.
