1. A battery module, comprising: a plurality of battery cells aligned in one direction, each battery cell having a vent portion;a cover covering the vent portions of the battery cells, the cover including: a gas outlet at a first end of the cover, anda top surface having a slope extending from the first end of the cover to a second end of the cover opposite the first end; andat least one rib on the top surface of the cover, the rib having an increasing height from the first end of the cover toward the second end of the cover, a distance between a top surface of the rib and a bottom surface of the cover being constant. 2. The battery module as claimed in claim 1, wherein a bottom surface of the rib faces the top surface of the cover and is configured to compensate for the slope of the top surface of the cover, a top surface of the rib being parallel with a bottom surface of the cover. 3. The battery module as claimed in claim 1, further comprising at least one reinforcing member on the top surface of the cover and intersecting the at least one rib. 4. The battery module as claimed in claim 1, wherein the cover has a hexahedral shape with an opening in a bottom surface, the bottom surface of the cover being opposite the top surface and facing the vent portions. 5. The battery module as claimed in claim 4, wherein the cover defines a gas flow path in fluid communication with the gas outlet and vent portions of the battery cells, the gas flow path being enclosed between the cover and the battery cells. 6. The battery module as claimed in claim 1, further comprising an insulating member on the vent portions, the insulating member being between the cover and the battery cells. 7. The battery module as claimed in claim 6, wherein the insulating member is a single body overlapping the entire cover and vent portions. 8. The battery module as claimed in claim 6, wherein the insulating member has a plurality of openings at regions corresponding to the vent portions. 9. The battery module as claimed in claim 6, wherein the insulating member includes a heat-resistant material. 10. The battery module as claimed in claim 6, wherein the insulating member is a gasket. 11. The battery module as claimed in claim 1, further comprising a housing configured to accommodate the plurality of battery cells. 12. The battery module as claimed in claim 11, wherein the housing includes: a pair of end plates spaced apart from each other, the plurality of battery cells being positioned between the end plates; andat least one connecting member connecting the pair of the end plates to each other. 13. The battery module as claimed in claim 12, wherein the connecting member includes side brackets connecting side surfaces of the pair of the endplates, and a bottom bracket connecting bottom surfaces of the end plates. 14. The battery module as claimed in claim 1, wherein the cover has a gradually decreasing height from the first end toward the second end, the height being measured along a direction normal to a plane of the vent portions. 15. The battery module as claimed in claim 1, wherein the top surface of the cover faces away from the vent portions and overlaps all the vent portions. 16. The battery module as claimed in claim 15, further comprising an insulating member between the cover and the vent portions, the insulating member being directly attached to the cover, and the cover having a hollow interior in fluid communication with the vent portions through openings in the insulating member. 17. The battery module as claimed in claim 1, wherein the top surface of the cover is sloped at a constant angle. 18. The battery module as claimed in claim 17, further comprising a sloped rib on the top surface of the cover, the rib being sloped at the constant angle and positioned to complement the slope of the top surface of the cover.
