A method for manufacturing a battery cell stack according to exemplary embodiments of the present invention includes an application step of spraying an adhesive resin composition on one surface of a battery cell in one direction by a plurality of nozzles, wherein the nozzles are disposed in a direction different from the one direction, and at least two nozzles of the plurality of nozzles apply the adhesive resin composition in amounts different from each other. Thereby, the adhesive resin composition is applied to one surface of a non-flat battery cell, and the application amount is controlled according to portions to be applied, so that the one surface may bring into contact with another surface of another battery cell adhered thereon over an entire area in which the adhesive resin composition is applied.
