Abstract
Disclosed herein is a separation-type connecting member, which electrically connects electrode terminals of unit cells. The connecting member comprises two or more separated connecting bodies, which are connected to the corresponding electrode terminals during the assembly of a secondary battery module, and which are electrically connected with each other by additional conductive members to complete the battery module. The present invention also provides a method of improving the performance of a battery module that is capable of connecting unit cells in parallel with each other to level the voltage of the unit cells while the battery module is manufactured using the connecting member, specifically, before the unit cells are connected in series with each other, or while the battery module is used, thereby minimizing the voltage difference between the unit cells.
