## Abstract

Provided is a case of pouch type cells, which is capable of stably protecting pouch type cells constituting a secondary battery used as a high power supply, and having excellent heat dissipation performance.

## Claims

### Claim 1

A case of pouch type cells for protecting pouch type cells 110 including a pouch 111 and an electrode tab 112 formed at one side of the pouch 111, the case comprising:
two sheets of aluminum covers 120 that support external surfaces of the pouch 111 of the two pouch type cells that are stacked; and
a partition 130 that is disposed between the pouch type cells 110 to prevent a short circuit.

### Claim 2 (depends on 1)

The case of claim 1, wherein the partition 130 includes a frame 131 that is hollow and a tap supporting portion 132 that is formed at one side of the frame and supports the electrode tab 112.

### Claim 3 (depends on 2)

The case of claim 2, wherein the partition 131 further includes a buffer pad 133 that is inserted into hollow space of the frame 131.

### Claim 4 (depends on 1)

The case of claim 1, wherein the aluminum cover 120 has a plurality of curved stack portions 122 formed by performing press processing such that an inner portion thereof is recessed and an outer portion thereof is protruded.

### Claim 5 (depends on 1)

The case of claim 1, wherein the aluminum cover 120 is applied with a curve gradient so as to be recessed in an inward direction in which the pouch type cells 110 are accommodated.
