Abstract

An apparatus mounts a battery cell stack to a frame that includes a base cover and a pair of side covers respectively extending from both ends of the base cover. The apparatus includes a support member to support the battery cell stack, and two films, wherein one side of each of the two films is respectively attachable to one of the pair of side covers of the frame, and another side of each of the two films is respectively attachable to one of two side surfaces of the battery cell stack, wherein, when the support member and the frame move toward each other, the two films are movable into the frame, and the battery cell stack is movable along the two films to be mounted to the frame.

First claim

What is claimed is:

1. A battery module comprising:
a battery cell stack including a plurality of battery cells, each battery cell having an electrode assembly and an electrolyte disposed within a battery case;
a frame in which the battery cell stack is disposed; and
a film disposed between the battery cell stack and the frame, wherein the film has a first side attached to the frame, and a second side attached to the battery case of an outermost battery cell of the battery cell stack, wherein the second side of the film is attached to the battery cell stack with a double-sided tape.

2. The battery module of claim 1 ,
wherein the frame includes a base cover and a pair of side covers.

3. The battery module of claim 1 ,
wherein the first side of the film is attached to a side cover of the frame, and the second side of the film is attached to a side surface of the battery cell stack.

4. The battery module according to claim 1 ,
wherein the film is an insulation film.

5. The battery module according to claim 1 ,
wherein the first side of the film is attached to the frame with a double-sided tape.

6. The battery module according to claim 1 , further comprising:
a heat conduction member coupled to the battery cell stack.

7. The battery module according to claim 3 , further comprising:
a second film disposed between the battery cell stack and the frame, wherein the second film has a first side attached to the frame, and a second side attached to the battery cell stack.

8. The battery module of claim 7 ,
wherein the first side of the second film is attached to another side cover of the frame, and the second side of the second film is attached to another side surface of the battery cell stack.

9. A battery module comprising:
a battery cell stack including a plurality of battery cells, each battery cell having an electrode assembly and an electrolyte disposed within a battery case;
a frame in which the battery cell stack is disposed; and
a first portion of film and a second portion of film at least partially overlapped between the battery cell stack and the frame, wherein the first portion of film is attached to the frame with a double-sided tape, wherein the second portion of film is attached to the battery cell stack with a double-sided tape, and wherein there is no double-sided tape between the first portion of film and the second portion of film.

10. The battery module of claim 9 ,
wherein the frame includes a base cover and a pair of side covers.

11. The battery module of claim 9 ,
wherein the first portion of film is attached to the frame, and the second portion side of film is attached to the battery case of an outermost battery cell of the battery cell stack.

12. The battery module according to claim 9 ,
wherein at least one of the first portion of film and the second portion of film is an insulation film.

13. The battery module according to claim 9 , further comprising:
a heat conduction member coupled to the battery cell stack.

14. The battery module of claim 9 ,
wherein the first portion of film is attached to a side cover of the frame, and the second portion of film is attached to a side surface of the battery cell stack.

15. The battery module according to claim 14 , further comprising:
a third portion of film and a fourth portion of film disposed and at least partially overlapped between the battery cell stack and the frame.

16. The battery module of claim 15 ,
wherein the third portion of film is attached to another side cover of the frame, and the fourth portion of film is attached to another side surface of the battery cell stack.
