摘要:
Disclosed herein is a battery pack case in which a battery module (32) having a plurality of stacked unit cells (30) is mounted. The battery pack case is provided at an upper part and a lower part thereof with a coolant inlet port (10′) and a coolant outlet port (20′), respectively. The coolant inlet port (10′) and the coolant outlet port (20′) are directed in opposite directions. The battery pack case is further provided with a coolant introduction part (40′) and a coolant discharge part. An upper end inside part of the coolant introduction part (40′) is configured in a structure in which an incline plane starting from an end opposite to the coolant inlet port (10′) has an inclination increasing toward the coolant inlet port (10′) with respect to the top of the cell stack.

Disclosed herein is a battery cell constructed in a structure in which an electrode assembly of a cathode/separator/anode structure is mounted in a battery case formed of a laminate sheet including a resin layer and a metal layer while the electrode assembly is connected to electrode terminals extruding out of the battery case, wherein the battery case is provided at an outer circumferential end thereof with a sealing part formed by thermally welding upper and lower parts of the laminate sheet, and a sheet-type member (‘a thermally conductive sheet’) to accelerate the dissipation of heat from the battery cell extends to the sealing part while the thermally conductive sheet partially covers the battery cell.

Disclosed herein is a battery module including two or more plate-shaped battery cells sequentially stacked, wherein each of the plate-shaped battery cells is constructed in a structure in which an electrode assembly of a cathode/separator/anode structure is mounted in a battery case formed of a laminate sheet including a resin layer and a metal layer, and a heat exchange member, including a plurality of heat exchange plates and a frame to which the heat exchange plates are connected, is mounted at one side of a stack of the battery cells for removing heat generated from the battery cells during the charge and discharge of the battery cells.
摘要:
Disclosed herein is a high-power, large-capacity battery module including a plurality of battery cells or unit modules connected in series to each other such that the battery cells or the unit modules are stacked while being in tight contact with each other or being adjacent to each other, wherein the battery module is fixed such that the stacked state of the battery cells or the unit modules is maintained even when the volume of the battery cells or the unit modules changes at the time of charging and discharging the battery cells or the unit modules, and a portion of an electrode terminal connection region between the battery cells or between the unit modules is weak with respect to the volume expansion of the battery cells or the unit modules such that an expansion stress caused by the swelling of the battery cells is concentrated on the electrode terminal connection region, whereby the electrode terminal connection region is broken, and therefore, an electrical cut-off occurs at the electrode terminal connection region, when the swelling exceeds a predetermined value.
