Abstract

An electrode stacking device includes a battery frame configured to stack at least one electrode and a separator, the battery frame including: a base part configured to support the at least one electrode and the separator; and a guide part provided on one side of the base part, the guide part including: a first guide part having at least one first accommodation part configured to accommodate an electrode terminal part of the at least one electrode; and a second guide part having at least one second accommodation part configured to accommodate an auxiliary guide part. The first guide part and the second guide part are located at opposite ends of the base part.

First claim

What is claimed is:

1 . An electrode stacking device, comprising:
a battery frame configured to stack at least one electrode and a separator, the battery frame including: a base part configured to be seated the at least one electrode and the separator; and a guide part located at one side of the base part, the guide part including:
a first guide part having at least one first accommodation part configured to accommodate an electrode terminal part of the at least one electrode; and
a second guide part having at least one second accommodation part configured to accommodate at least one auxiliary guide part,
wherein the first guide part and the second guide part are located at opposite ends of the base part.

2 . The electrode stacking device of claim 1 , wherein the first guide part and the second guide part are disposed to face each other, form a spaced apart space, and are spaced apart from each other.

3 . The electrode stacking device of claim 2 , wherein the electrode and the separator are disposed in the spaced apart space.

4 . The electrode stacking device of claim 1 , wherein the second guide part has a pair of side walls facing each other.

5 . The electrode stacking device of claim 4 , wherein each side wall of the second guide part includes the at least one second accommodation part configured to accommodate at least one auxiliary guide part.

6 . The electrode stacking device of claim 1 , wherein the base part includes a detachment groove configured to enable detachment of the at least one electrode and the separator.

7 . The electrode stacking device of claim 1 , wherein the base part and the guide part are formed integrally.

8 . The electrode stacking device of claim 1 , wherein the battery frame further includes the at least one auxiliary guide part that is detachable from the second guide part.

9 . The electrode stacking device of claim 8 , wherein the at least one electrode includes a cathode and an anode, and
wherein the at least one auxiliary guide part includes:
a first auxiliary guide part having a third accommodation part configured to accommodate the cathode; and
a second auxiliary guide part having a fourth accommodation part configured to accommodate the anode.

10 . The electrode stacking device of claim 8 , wherein the at least one auxiliary guide part includes a fastening protrusion and a fastening groove configured to be coupled to the second guide part.
