Battery cartridge for novel structure and open type battery module containing the same

The present invention is configured to include an inner frame member which is interposed between an external frame member and that member of the pair can hold the unit cells, the unit cells are mounted between the frame members, the inner frame member in these has a high density and mechanical strength as a structural bar, to provide a plurality, and of the battery cartridge in the through-hole is formed, open-cell module that is configured to contain it, communicating with the outside in the unit cells mounted state as it is possible to minimize the size of the battery system, to mechanical rigidity is stably mounted in a small unit cell, and can achieve an effective heat dissipation of the unit cell.
