Abstract
Disclosed herein are a battery cell including an electrode assembly configured to have a structure including cathodes, anodes, and separators respectively disposed between the cathodes and the anodes, the electrode assembly being provided with a through hole in a direction in which the electrodes are stacked, and a battery case provided at each side thereof with an opening communicating with the through hole and a battery pack including the same.
Claims23
A battery cell comprising:
- an electrode assembly configured to have a structure comprising cathodes, anodes, and separators respectively disposed between the cathodes and the anodes, the electrode assembly being provided with a through hole in a direction in which the electrodes are stacked;
- and
- a battery case provided at each side thereof with an opening communicating with the through hole,
- wherein a welded portion or a thermally bonded sealing portion is formed along an inside of the opening.
A battery cell comprising:
- an electrode assembly configured to have a structure comprising cathodes, anodes, and separators respectively disposed between the cathodes and the anodes, the electrode assembly being provided with a through hole in a direction in which the electrodes are stacked;
- and
- a battery case provided at each side thereof with an opening communicating with the through hole,
- wherein a cathode lead and an anode lead connected to the electrode assembly protrude inwardly of the opening of the battery case.
A battery cell comprising:
- an electrode assembly configured to have a structure comprising cathodes, anodes, and separators respectively disposed between the cathodes and the anodes, the electrode assembly being provided with a through hole in a direction in which the electrodes are stacked;
- and
- a battery case provided at each side thereof with an opening communicating with the through hole,
- wherein a damping member is mounted to an inside of the through hole of the electrode assembly.
A battery cell comprising:
- an electrode assembly configured to have a structure comprising cathodes, anodes, and separators respectively disposed between the cathodes and the anodes, the electrode assembly being provided with a through hole in a direction in which the electrodes are stacked;
- and
- a battery case provided at each side thereof with an opening communicating with the through hole,
- wherein an opening support member is mounted along an inside of the opening of the battery case.
A battery cell comprising:
- an electrode assembly configured to have a structure comprising cathodes, anodes, and separators respectively disposed between the cathodes and the anodes, the electrode assembly being provided with a through hole in a direction in which the electrodes are stacked;
- and
- a battery case provided at each side thereof with an opening communicating with the through hole,
- wherein the electrode assembly is configured to have a structure in which the separators are longer than the cathodes and the anodes toward a center of the through hole and ends of the separators adjacent to the through hole are bent to cover edges of the cathodes or the anodes.
