## Abstract

Provided is a battery module including: an electrode assembly including a plurality of cathode plates, a plurality of anode plates, and a plurality of separators each interposed between the plurality of cathode plates and the plurality of anode plates; a pouch receiving the electrode assembly therein; and an electrode retaining structure received together with the electrode assembly in the pouch and having a space capable of retaining an electrolyte.

## Claims

### Claim 1

A battery module comprising:
an electrode assembly including a plurality of cathode plates, a plurality of anode plates, and a plurality of separators each interposed between the plurality of cathode plates and the plurality of anode plates;
a pouch receiving the electrode assembly therein; and
an electrode retaining structure received together with the electrode assembly in the pouch and having a space capable of retaining an electrolyte.

### Claim 2 (depends on 1)

The battery module of claim 1, wherein the electrode retaining structure has the same thickness as that of the electrode assembly.

### Claim 3 (depends on 1)

The battery module of claim 1, wherein the electrode retaining structure is positioned at a lower portion of the electrode assembly.

### Claim 4 (depends on 1)

The battery module of claim 1, wherein the electrode retaining structure is positioned at a side of the electrode assembly.

### Claim 5 (depends on 1)

The battery module of claim 1, wherein the electrode retaining structure is positioned at an upper portion of the electrode assembly and is positioned at a position at which it does not interfere with an anode tap and a cathode tap of the electrode assembly.

### Claim 6 (depends on 1)

The battery module of claim 1, wherein the electrode retaining structure is manufactured in a lattice shape.

### Claim 7 (depends on 1)

The battery module of claim 1, wherein the electrode retaining structure is manufactured in a pipe shape in which it has a plurality of holes perforated therein.
