SECONDARY BATTERY MODULE

摘要

PURPOSE: A secondary battery module is provided to simplify the structure of the module itself by simply arranging unit cells and by simplifying the structure of a connector electrically connecting the unit cells. CONSTITUTION: A secondary battery module comprises plural unit cells and a connector(20). The unit cells include an electrode group(11), a case connected with a positive electrode or a negative electrode inside the electrode group, and an electrode terminal(14) penetrating a cap plate covering the case. The connector is inserted into one electrode terminal of one unit cell and one end is fixed to the electrode terminal using a nut(141) screwed to the electrode terminal. The other end of the connector is connected to the case by welding.
