## Abstract

A flexible package is disclosed. A support module is disposed in the flexible body and comprises a first structural member, a second structural member and at least two cushioning members. At least one flexible cell is in the placing space formed by the structural members and the cushioning members when the support module is under the binding force of the flexible body. When the flexible body and the flexible cell bending, the stress acting on the flexible cell can be reduced by the first structural member, the second structural member and the cushioning members. Therefore, the electrode layers inside the flexible cell can be protected and improve the integrity, safety, cycle life and bendability of the flexible cell.

## Claims

### Claim 1

A flexible package for placing at least a flexible battery cell, comprising:
a flexible body having at least a fixed part, a first inner surface and a second inner surface, wherein the fixed part is disposed on the flexible body and provides a binding force to the flexible body; and
a support module disposed in the flexible body, comprising:
a first structural member disposed adjacent to the first inner surface;
a second structural member disposed adjacent to the second inner surface and corresponding to the first structural member; and
at least two cushioning member interposed between a peripheral edge of the first structural member and the second structural member to resist the binding force and to support the first structural member and the second structural member, wherein the flexible battery cell is disposed in a placing space formed by the first structural member, the second structural member and the cushioning members.

### Claim 2 (depends on 1)

The flexible package of claim 1, wherein the friction factor of at least one of the first structural member and the second structural member is smaller than the friction factor of the flexible body.

### Claim 3 (depends on 1)

The flexible package of claim 1, wherein the surface of the flexible cell is further dispose a sliding layer.

### Claim 4 (depends on 1)

The flexible package of claim 1, wherein these cushioning members are disposed at intervals.

### Claim 5 (depends on 1)

The flexible package of claim 1, wherein each of these cushioning members is connected to at least one of the first structural member and the second structural member.

### Claim 6 (depends on 1)

The flexible package of claim 1, wherein the structure of these cushioning members is a compressible body, an incompressible body or a combination thereof.

### Claim 7 (depends on 1)

The flexible package of claim 1, wherein the material of these cushioning members is selected from the group consisting of a metal material, a ceramic material, a fiber, a polymer material and a combination thereof.

### Claim 8 (depends on 1)

The flexible package of claim 1, wherein the material of these structural members is selected from the group consisting of a metal material, a ceramic material, a fiber, a glass, a polymer material and a combination thereof.

### Claim 9 (depends on 1)

The flexible package of claim 1, wherein the material of the flexible body is selected from the group consisting of cloth, fiber, leather, metal, polymer material and a combination thereof.

### Claim 10 (depends on 1)

The flexible package of claim 1 wherein the fixed part is selected from the group consisting of a linear object, a striped article, a fastener or a rivet, a colloid and a combination thereof.
