Abstract
The present invention provides a lithium secondary battery which includes an electrode assembly to which an electrode tap is attached, an electrode tap receptor configured to house a portion of the electrode assembly such that a portion of the electrode tap protrudes to an outside, and a case configured to surround the electrode assembly and seal the electrode assembly together with the electrode tap receptor, wherein the electrode tap receptor includes a gas barrier layer.
Claims10
A lithium secondary battery comprising:
- an electrode assembly to which an electrode tap is attached;
- an electrode tap receptor configured to house a portion of the electrode assembly;
- wherein the electrode tap receptor comprises a hole through which a portion of the electrode tap protrudes to an outside;
- and
- a case formed from one sheet configured to surround the electrode assembly,
- wherein an end of the electrode tap receptor and an end of the case partially overlap each other such that the end of the case is disposed over the end of the electrode tap receptor to seal the electrode assembly,
- wherein the portion of the electrode tap extends through an end of the case as the portion of the electrode tap extends through the hole of the electrode tap receptor, and
- wherein the electrode tap receptor includes a gas barrier layer.
