Abstract
A method and device for sealing an electrode assembly, which includes a plurality of electrodes stacked alternately with a separator therebetween, include a nest that supports the electrode assembly and a hot air blower that blows hot air toward a corner portion of the electrode assembly to seal the corner portion in a non-contact manner. The sealing may be performed in a non-contact method to minimize the impact on or damage to the electrode assembly other than the portions or regions to be sealed, which is typically caused by physical contact during the sealing process. Moreover, conditions for performing the sealing may be controlled to adaptively secure uniform and stable sealing quality.
Claims6
A method for sealing an electrode assembly having a plurality of electrodes stacked alternately with a separator therebetween, the method comprising:
- seating the electrode assembly on a nest;
- and
- sealing the electrode assembly by blowing hot air toward a corner portion of the electrode assembly,
- wherein the corner portion includes a portion of the separator, and
- wherein the step of sealing the electrode assembly includes melting the portion of the separator in the corner portion by the hot air.
