1. A method of manufacturing a battery cell assembly in which a plurality of battery cells are stacked, the method comprising:
a step of coupling battery cells adjacent to each other among the plurality of battery cells using a one-component liquid material,
wherein the one-component liquid material is coated onto at least one battery cell of the battery cells adjacent to each other by a spray-coating method, and
wherein the step of coupling the battery cells adjacent to each other using the one-component liquid material includes using a spray valve to spray the one-component liquid material from a lower part of one of the battery cells adjacent to each other toward the respective battery cell, thereby coating the one-component liquid material onto a lower surface of the respective battery cell.
