Electrode For All Solid State Battery

Abstract: An electrode for an all-solid-state battery is provided comprising granules each including a core portion and a coating layer, wherein the core portion contains an active material, a first conductive material, and a binder, and the coating layer is disposed in contact with the outside of the core portion and contains a solid electrolyte and a second conductive material. According to an embodiment of the present invention, the first conductive material and the second conductive material are different from each other in terms of size or shape. The first conductive material has an aspect ratio of 4000 to 6000 and a BET specific surface area of 100 ?/g to 300 ?/g. The second conductive material has an aspect ratio of 100 to 300 and a BET specific surface area of 10 ?/g to 30 ?/g. The granules have an excellent electrical network formed to the inside thereof even under all-solid conditions, contributing to the improvement in battery performance when an electrode containing the granules is applied to all-solid-state batteries.
