A secondary battery module comprises at least two battery cells laminated to a designated depth, in which an air guide block is interposed between leveled surfaces of the neighboring battery cells and a fixing block is interposed between protruded surfaces of the neighboring battery cells, the air guide blocks and the fixing blocks are fixed to each other using fasteners, and corresponding electrode terminals of the neighboring battery cells are interconnected in series by conductive and insulating connection members serving as bolts and nuts, thereby being conveniently installed in various industrial facilities and electric vehicles.

Secondary battery module

Disclosed is a secondary lithium battery module. The secondary lithium battery module comprising a plurality of secondary lithium unit-batteries including anode and cathode terminals having a hole, which terminals are protruded in one direction in parallel to each other and alternately aligned; a receiving module having a plurality of non-metallic receiving unit-modules, each unit-module having recesses for receiving the anode and cathode terminals of the secondary lithium unit-batteries therein, each recess having a fixing hole; a metal block having a fixing hole and a contact plate and aligned in the recesses of the receiving unit-modules such that the metal block makes contact with at least one of the anode and cathode terminals of the secondary lithium unit-batteries accommodated in the recesses of the receiving unit-modules; a circuit board having a shape corresponding to a shape of the receiving module and aligned on an upper surface of the receiving module, the circuit board having recesses corresponding to the recesses of the receiving module and copper wirings formed at lateral portions of the recesses in order to make contact with the contact plate of the metal block; and a coupling member inserted into the recesses of the receiving module, the anode and cathode terminals of the secondary lithium unit-batteries accommodated in the recesses, and the fixing hole of the metal block making contact with at least one of the anode and cathode terminals so as to fixedly assemble the receiving module, secondary lithium unit-batteries and the metal block with each other.
