Abstract:
1. A middle- or large-sized battery module having a structure in which two or more plate-shaped secondary battery cells (‘battery cells’) are arranged in a lateral direction thereof, wherein the battery cells have electrode terminals arranged in the same direction, plate-shaped electrode terminal connecting members to electrically connect the battery cells to one another are electrically connected to oriented surfaces of the electrode terminals of the battery cells, each of the electrode terminal connecting members is provided at a top and/or bottom thereof with a coupling structure to interconnect electrode terminal connecting members, and at least one end of an insulating joint member coupled in the coupling structure is supported by a module case, wherein the coupling structure comprises a frame configured in a hollow structure (‘hollow frame’) formed in the lateral direction of the battery cells, and the insulating joint member, configured in a bar type structure, is fixedly inserted through the hollow frame in a state in which a plurality of electrode terminal connecting members are arranged in the lateral direction thereof.
