Abstract

The present invention provides an isostatic pressurization method for an electrode assembly comprising a positive electrode comprising a positive electrode current collector and a positive electrode active material layer, a negative electrode comprising a negative electrode current collector and a negative electrode active material layer, and a solid electrolyte layer, wherein the solid electrolyte layer is laminated to bond one side to the negative electrode active material layer, and a positive electrode is laminated to bond the other side of the solid electrolyte layer to the positive electrode active material layer, wherein the electrode assembly has a stacked form in which the negative electrode protrudes beyond the end of the positive electrode thereby forming a step,wherein the isostatic pressurization is performed with a protective member in the form of a band extending vertically from the outer circumferential surface of the negative electrode end protruding from the electrode assembly to the positive electrode, wherein a space formed by the step is located between the protective member and the positive electrode; and an all-solid-state battery comprising the electrode assembly and the protective member.
