All Solid State Battery Manufacturing Method

Abstract: Disclosed is an all-solid-state battery manufacturing method in which respective unit cells undergo warm isostatic pressing, and then are stacked so that shorting occurring at side parts during operation of a battery is inhibited. The all-solid-state battery manufacturing method comprises the steps of: a) sequentially stacking a solid electrolyte and a cathode on one surface or each of two surfaces of an anode, thereby manufacturing a mono-cell or a bi-cell; b) performing warm isostatic pressing on the manufactured mono-cell or bi-cell; and c) stacking two or more mono-cells or bi-cells having undergone warm isostatic pressing and interposing a cathode current collector between one cell and another cell, thereby causing each of two surfaces of the interposed cathode current collector to come in contact with the cathode.
