  "claims": [
    "9. The battery module of claim 7, wherein a length of each of the protrusions is 2 mm to 4 mm. 10. The battery module of claim 1, wherein: thicknesses of the first layer and the third layer are each 0.1 mm to 0.3 mm; and a thickness of the second layer is 0.5 mm to 2 mm. 11. A battery module comprising: a plurality of battery cells; busbars electrically connecting the plurality of battery cells; and a cover portion covering the bus bars, wherein the cover portion includes a first layer, a second layer positioned on the first layer, and a third layer positioned on the second layer, and the cover portion includes protrusions positioned protruding toward the plurality of battery cells and between the bus bars. 12. The battery module of claim 11, wherein a lower surface of each of the protrusions is positioned lower than upper surfaces of the bus bars. 13. The battery module of claim 11, wherein a length of each of the protrusions is 2 mm to 4 mm. 14. The battery module of claim 11, wherein the protrusions include at least one of flame retardant silicone, ethylene propylene diene monomer (EPDM), fluorosilicone, polytetrafluoroethylene (PTFE), para-aramid fiber, fluoroelastomer (FKM), polyvinyl chloride (PVC), or polyurethane. 15. The battery module of claim 11, wherein: thicknesses of the first layer and the third layer are each 0.1 mm to 0.3 mm; and a thickness of the second layer is 0.5 mm to 2 mm. 16. The battery module of claim 11, wherein the first layer and the third layer each include at least one of mica, ceramic fiber, glass fiber, or silica fiber. 17. The battery module of claim 11, wherein the second layer includes at least one of aerogel, polyurethane foam, or phenolic foam. 18. The battery module of claim 17, wherein at least one of the aerogel, the polyurethane foam, or the phenol foam is included in the second layer in an amount of 60% to 90% weight. 19. The battery module of claim 11, wherein a width of each of the protrusions is greater than a width of each of the bus bars. 20. The battery module of claim 1, wherein: an upper surface of each of the bus bars is spaced apart from a lower surface of the cover portion by a distance; and a distance between the upper surface of each of the bus bars and the lower surface of the cover portion is 0.1 mm to 5 mm."
