Abstract

A cell cartridge having a first pouch cell having a first fixing portion extending from a sealing portion thereof, a second pouch cell having a second fixing portion extending from a sealing portion thereof, and a cartridge configured to accommodate a cell stack formed by stacking the first pouch cell and the second pouch cell is provided. The first fixing portion is bent toward the second pouch cell to restrict movement of the second pouch cell. The second fixing portion is bent toward the first pouch cell to restrict movement of the first pouch cell.

Claims (38)

1. A cell cartridge, comprising:

a first pouch cell having a plurality of first fixing portions extending from a sealing portion thereof;

a second pouch cell having a plurality of second fixing portions extending from a sealing portion thereof; and

a cartridge configured to accommodate a cell stack formed by stacking the first pouch cell and the second pouch cell,

wherein each first fixing portion is bent toward the second pouch cell to restrict movement of the second pouch cell, and

wherein each second fixing portion is bent toward the first pouch cell to restrict movement of the first pouch cell.

2. The cell cartridge according to claim 1 ,

wherein the first fixing portions are spaced apart along a periphery of the first pouch cell, and

wherein the second fixing portions are spaced apart along a periphery of the second pouch cell.

3. The cell cartridge according to claim 2 ,

wherein the first fixing portions are formed in a region except for an area where an electrode lead of the first pouch cell is drawn, and

wherein the second fixing portions are formed in a region except for an area where an electrode lead of the second pouch cell is drawn.

4. The cell cartridge according to claim 2 ,

wherein the first fixing portions and the second fixing portions are arranged alternately along a periphery of the cell stack.

5. The cell cartridge according to claim 1 ,

wherein each first fixing portion extends to an accommodation portion of the second pouch cell and is attached to the second pouch cell, and

wherein each second fixing portion extends to an accommodation portion of the first pouch cell and is attached to the first pouch cell.

6. The cell cartridge according to claim 1 ,

wherein each first fixing portion and each second fixing portion are integrally formed with the sealing portion of the first pouch cell and the sealing portion of the second pouch cell, respectively.

7. A battery module, comprising:

a cell cartridge stack formed by stacking a plurality of cell cartridges defined in claim 1 ; and

a pair of end plates configured to cover opposite surfaces of the cell cartridge stack.

8. The battery module of claim 7 , further comprising a fastening clip extending from a first end plate of the pair of end plates to a second end plate of the pair of end plates.

9. The cell cartridge of claim 1 , wherein the cartridge comprises:

a first cartridge; and

a second cartridge, and

wherein the first pouch and the second pouch are located between the first cartridge and the second cartridge.

10. The cell cartridge of claim 9 , wherein each of the first cartridge and the second cartridge includes a through hole to receive a bolt.

11. A cell cartridge, comprising:

a first pouch cell having a plurality of first fixing portions extending from a sealing portion thereof;

a second pouch cell having a plurality of second fixing portions extending from a sealing portion thereof; and

a cartridge configured to accommodate a cell stack formed by stacking the first pouch cell and the second pouch cell,

wherein each first fixing portion is bent toward the second pouch cell to restrict movement of the second pouch cell,

wherein each second fixing portion is bent toward the first pouch cell to restrict movement of the first pouch cell,

wherein the first fixing portions are spaced apart along a periphery of the first pouch cell,

wherein the second fixing portions are spaced apart along a periphery of the second pouch cell,

wherein at least one of the first fixing portions is opposite the area where the electrode lead of the first pouch cell is drawn, and

wherein at least one of the second fixing portions is opposite the area where the electrode lead of the second pouch cell is drawn.
