Battery cell having frame and method for manufacturing the same

1. A battery cell assembly comprising:

a battery cell; and

a frame having a vertical frame portion and a horizontal frame portion with upper sides,

wherein the battery cell includes a case and a battery part inserted into the case, the case having a sealing surface formed at a circumferential portion of an outer side thereof, into which the battery part is inserted,

wherein the frame is joined to the sealing surface of the battery cell,

wherein the frame has an inserted groove formed in a lower surface thereof, and

wherein the sealing surface of the battery cell is bent such that an end of the sealing surface faces upward, and is insertion-coupled with the inserted groove;

wherein a gap exists between the frame and the battery cell; and

a sealing member provided within the gap to seal the gap and also cover the upper sides of the frame.

2. A method for manufacturing a battery cell assembly having a frame having a vertical frame portion and a horizontal frame portion with upper sides, the method comprising:

injection-molding the frame;

bending an end of a sealing surface of a battery cell upward and then insertion-coupling the end of the sealing surface of the battery cell with an inserted groove of the frame;

joining the frame and the battery cell to each other defining a gap between the frame and the battery cell; and

coating a sealing member at a join portion of the frame and the battery cell to fill the gap and also to cover the upper sides of the frame.

3. The method of claim 2 , wherein the sealing member is a resin, and

wherein the coating of the sealing member includes:

coating and then hardening the sealing member; and

compressing the sealing member.

4. The method of claim 2 , wherein the sealing member is a solid finishing material, and

wherein the coating of the sealing member includes:

coating the solid finishing material and then melting the solid finishing material using a heat source.
