Disclosed herein are a secondary battery, which is formed in the shape of a plate and has an electrode assembly mounted in a battery case made of a laminated sheet including a metal layer and a resin layer, wherein the secondary battery is constructed in a structure in which independent coupling type frame members are mounted to the outside part of a sheathing member serving as the battery case, and a medium- or large-sized battery module including the same as a unit cell. Consequently, the secondary battery has a high mechanical strength and a large sealing force. Furthermore, the electrical connection is accomplished without bending the electrode leads. Also, the battery module, which is constructed with the secondary battery as a unit cell, can be manufactured with a compact structure and a relatively light weight. Furthermore, the assembly process of the battery module is greatly simplified. The structural stability of the battery module according to the present invention is very high, and therefore, the battery module can be preferably used as a power source for electric vehicles, hybrid electric vehicles, electric motor cycles, and electric bicycles.

Disclosed herein is an apparatus for manufacturing a secondary battery by performing insert injection molding with respect to a portion of a battery cell while the battery cell is located in a mold, wherein the apparatus comprises a pair of upper and lower molds, at which are formed shapes corresponding to the battery cell, the upper and lower molds are provided at the inside surfaces thereof with elastic members, and the elastic members are constructed in a structure in which the elastic members support a cell body of the battery cell and isolate a non-molding region from a molding region while the battery cell is mounted in the upper and lower molds. The secondary battery manufacturing apparatus according to the present invention has the effect of preventing a battery case from being damaged due to the contact between the battery case and the mold when the mold is brought into tight contact with the cell body of the battery cell during insert injection molding to form a molding member at a specific region of the secondary battery, and effectively preventing a material for insert injection molding, which is injected into the molding region, from being injected into the non-molding region.

Disclosed herein is a heat exchange system for battery packs, which controls the temperature of a medium- or large-sized battery pack including a plurality of unit cells such that the battery pack can be operated under the optimum operating conditions. The heat exchange system includes an air inlet port and an air outlet port formed at one side of a housing surrounding the outer surface of the battery pack so as to form a predetermined flow channel, through which air flows, a driving fan mounted in the flow channel for driving the air to flow through the flow channel, and a Peltier element mounted at the air inlet port for controlling the temperature of air introduced into the air inlet port. In the heat exchange system according to the present invention, the thermoelectric element is mounted inside the air inlet port, through which air for cooling the battery pack is introduced into the heat exchange system. Consequently, the present invention has the effect of easily controlling the optimum operating temperature of the battery pack, reducing influences caused by external conditions, and decreasing noise and vibration.

Disclosed herein is a secondary battery module constructed approximately in a rectangular parallelepiped structure. The battery module includes a pair of side members (right and left side members) having pluralities of grooves formed at the inside surfaces thereof such that the sides of unit cells are securely fitted in the grooves and at least one connection member integrally formed with the side members such that the side members are spaced apart from each other by the width of the unit cells while the grooves of the side members face each other. A medium- or large-sized battery system is manufactured using one or more secondary battery module. The secondary battery module allows a plurality of unit cells to be mounted in the battery module with high density. Consequently, the total size of the battery system can be considerably reduced, and the electrical connection between the electrodes is highly stable. Furthermore, a risk of an engineer or a user being exposed to the electrical short-circuits is minimized, and a risk of electrical short-circuits due to external forces is greatly reduced.
