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.
L~invention concerne un processus pour la préparation d~un module de batterie secondaire. Le processus comprend la formation d~orifices de passage de couplage ayant des formes spécifiques au niveau de bornes d~électrode en forme de plaque d~une pluralité de cellules unitaires, l~empilement des cellules unitaires les unes sur les autres, et l~insertion d~éléments de couplage à travers les orifices de passage de couplage pour coupler les cellules unitaires les unes avec les autres. En conséquence, le couplage solide et la connexion électrique entre les cellules unitaires sont réalisés sans utiliser d~éléments additionnels, tels que des cartouches, et donc, un module de batterie compact ayant une force de couplage importante est préparé.
