International ClassH01M 2/04AbstractA battery module includes a battery cell having a laminate overcoat, a pair of rubber sheets, a pair of pressure plates, and a pair of housing members from the internal to the external of the battery module. An intervention member including four poles is interposed between the pressure plate and the housing member at the central area of the battery cell to alleviate the stress concentration on the peripheral area of the battery cell. The intervention member may be formed separately from or integrated with the pressure plate. |
