Abstract
The present disclosure relates to an electrode assembly for an all-solid-state battery with improved safety, and more particularly, to an electrode assembly of a new structure designed to prevent the damage of a solid electrolyte layer caused by a step formed in a negative electrode layer due to changes in thickness of the negative electrode layer, such as an increase or decrease in thickness at part of the negative electrode layer, during charging/discharging. The electrode assembly is characterized by comprising a protective layer having an opening, interposed between the negative electrode and the solid electrolyte layer.
