Abstract: A battery module includes battery cells arranged along a longitudinal direction of the battery module with respective long side surfaces of adjacent ones of the battery cells facing each other and heat-insulating partition walls interposed between the respective long side surfaces of the adjacent ones of the battery cells. A heat-insulating partition wall of the heat-insulating partition walls includes a heat-insulating sheet and a frame around an edge of the heat-insulating sheet. The heat-insulating sheet has a plate shape and comprises pores therein. The heat-insulating sheet is coupled between the respective long side surfaces of the adjacent ones of the battery cells.

Abstract: A battery module with a plurality of battery cells arranged in a first direction in a battery array, the battery module including a plurality of barriers in which a pair of adjoining ones of the barriers mount a battery cell therebetween, a frame having at least a pair of opposed frame members, the battery array and the barriers being between the opposed frame members and disposed internally thereof, the frame including a pair of end blocks at outermost sides of the battery array, side frames connecting the end blocks, and a degassing portion overlying vent portions of each of the plurality of battery cells and providing a passage for directing vented gas from the battery cells away from the battery module, the degassing portion rigidly supporting the battery cells and barriers of the battery array within the frame.

Abstract: A battery module includes a first battery cell, a first barrier, and a second barrier, the first battery cell being between the first barrier and the second barrier, wherein a first opening is in flow communication with a first space defined between a first side of the first battery cell and a first side portion formed by at least one of the first and second barriers, the first space being in flow communication with a second space defined between a second side of the first battery cell and a second side portion formed by at least one of the first and second barriers.
