Abstract

Disclosed are a method for manufacturing a battery in which an A/S label is disposed in a plastic member of the battery and a battery made by the method. In the battery made by the method according to the present invention, the A/S label is prevented from being separated and disappeared and from being exchanged or modified arbitrarily by a battery user.

Claims (20)

1. A method for manufacturing a battery comprising a battery cell accommodating an electrolyte and an electrode assembly, a plastic molded body, and an after service label, the method comprising the step of:

providing a battery cell accommodating an electrolyte and an electrode assembly; then

disposing an after service label on an outer side of the battery cell; and then

forming a plastic molded body on an outer side of the battery cell by molding so that the after service label is fixed on the outer side of the battery cell by the plastic molded body,

wherein a portion of the after service label is exposed, and a circumferential portion of the after service label is buried in the plastic molded body.

2. The method according to claim 1 , wherein

the step of disposing the after service label in the plastic molded body comprises the step of attaching the after service label to the outer side of the battery cell; and

the step of forming the plastic molded body comprises the steps of:

locating the battery cell to which the after service label is attached in a molding space of a mold; and

forming the plastic molded body by injecting a fused resin into the mold onto the outer side of the battery cell and onto the circumferential portion of the after service label so that a portion of the after service label is exposed to outside.

3. The method according to claim 2 , wherein the after service label is a submersion label.

4. The method according to claim 2 , wherein the plastic molded body is an outer case of the battery.

5. The method according to claim 2 , wherein a binding protrusion portion is formed at a portion of the plastic molded body in the step of forming the plastic molded body.

6. The method according to claim 2 , wherein the fused resin for forming the plastic molded body is a thermal fused resin or a volatile fused resin.

7. A method for manufacturing a battery comprising a battery cell accommodating an electrolyte and an electrode assembly, a plastic molded body, a protection circuit portion, and an after service label, the method comprising the step of:

providing the battery cell accommodating an electrolyte and an electrode assembly;

providing the protection circuit portion;

pre-assembling the battery cell and the protection circuit portion by fixing an electrode terminal of the battery cell and a corresponding electrode terminal of the protection circuit portion;

attaching the after service label to the outer side of one of the battery cell and the protection circuit portion; and

locating the battery cell assembly comprising the battery cell, the protection circuit portion, and the after service label in a molding space of a mold and forming the plastic molded body by injecting a fused resin into the mold onto the outer side of the battery cell and onto a circumferential portion of the after service label so that a portion of the after service label is exposed to the outside.
