Abstract

An energy storage module includes: a plurality of battery cells arranged in a length direction; a plurality of insulation spacers; a cover member including an internal receiving space; a top plate coupled to a top of the cover member, the top plate including ducts respectively corresponding to vents of the battery cells and having opening holes respectively corresponding to the insulation spacers; a top cover coupled to a top of the top plate and having discharge holes respectively corresponding to the ducts; and an extinguisher sheet between the top cover and the top plate, the extinguisher sheet being configured to emit a fire extinguishing agent at a temperature exceeding a reference temperature, the top cover including protrusion parts on a bottom surface thereof, the protrusion parts covering an exhaust region and being coupled to an exterior of each of the ducts.

Claims (16)

1. An energy storage module comprising:

a plurality of battery cells arranged in a length direction such that long side surfaces of adjacent battery cells of the battery cells face one another;

a plurality of insulation spacers, at least one of the insulation spacers being between the long side surfaces of each adjacent pair of the battery cells;

a cover member comprising an internal receiving space configured to accommodate the battery cells and the insulation spacers;

a top plate coupled to a top of the cover member, the top plate comprising ducts respectively corresponding to vents of the battery cells and having opening holes respectively corresponding to the insulation spacers; and

a top cover coupled to a top of the top plate and having discharge holes respectively corresponding to the ducts;

wherein the top cover comprises protrusion parts on a bottom surface thereof, the protrusion parts covering an exhaust region and being coupled to an exterior of each of the ducts, wherein each of the insulation spacers comprises a first sheet including a heat-insulating material and second sheets adhered to opposite surfaces of the first sheet and sealing the heat-insulating material.

2. The energy storage module of claim 1 , wherein the first sheet comprises a partition wall having a honeycomb structure, and the heat insulating material accommodated in the partition wall.

3. The energy storage module of claim 2 , wherein the heat insulating material comprises at least one of an aerogel or an oxide having a high heat-insulating property.

4. The energy storage module of claim 2 , wherein the partition wall has opposite sides open, and the second sheets are coupled to the opposite surfaces of the first sheet to seal the partition wall.

5. The energy storage module of claim 1 , wherein the first sheet is covered and sealed by the second sheets.

6. The energy storage module of claim 5 , wherein each of the second sheets includes a first region on which the first sheet is seated, and a second region coupled to a side of the first region, and the second region is folded along a boundary with the first region to cover the first sheet.

7. The energy storage module of claim 6 , wherein each of the second sheets further includes a third region coupled to another side of the first region, and sequentially folded along a boundary with the first region to cover the first sheet.

8. The energy storage module of claim 7 , wherein the second region is bent to allow an end thereof to be coupled to one surface of the first sheet, and the third region is bent to allow an end thereof to pass through the end of the second region to then seal the first sheet.

9. The energy storage module of claim 7 , wherein an adhesive is formed on an inner surface of the third region, or an adhesive sheet is coupled in a direction perpendicular to an end of the third region to fix the end of the third region.

10. The energy storage module of claim 1 , wherein opposite sides of the first sheet are covered by the second sheets, and spray coating is performed on a remaining exposed side.
