Abstract
Disclosed herein is a process for preparation of a secondary battery module. The process includes forming coupling through-holes having specific shapes at plate-shaped electrode terminals of a plurality of unit cells, stacking the unit cells one on another, and inserting coupling members through the coupling through-holes to couple the unit cells with each other. Consequently, the secure coupling and the electrical connection between the unit cells is accomplished without using additional members, such as cartridges, and therefore, a compact battery module having high coupling force is prepared.
