Abstract
A battery cell includes an electrode assembly in which a plurality of electrode plates are stacked and an uncoated portion protrudes to at least one side along a first direction; and a cap assembly disposed to face the electrode assembly in the direction of protrusion of the uncoated region and including a current collector electrically connected to the uncoated portion, wherein at least a portion of the current collector protrudes toward the electrode assembly in the first direction to face and contact the uncoated portion in a direction perpendicular to the first direction.
Claims20
A battery cell, comprising:
- an electrode assembly in which a plurality of electrode plates are stacked and a foil protrudes to at least one side along a first direction;
- and
- a cap assembly disposed to face the electrode assembly in the first direction, and comprising a current collector electrically connected to the foil,
- wherein at least a portion of the current collector protrudes toward the electrode assembly in the first direction to face and contact the foil in a direction perpendicular to the first direction.
A battery pack, comprising:
- a housing having one or more housing spaces;
- and
- a plurality of battery cells stacked within the housing,
- wherein each battery cell comprises:
- an electrode assembly in which a plurality of electrode plates are stacked and a foil protrudes to at least one side along a first direction;
- and
- a cap assembly disposed to face the electrode assembly in the first direction, and comprising a current collector electrically connected to the foil,
- at least a portion of the current collector protrudes toward the electrode assembly in the first direction to face and contact the foil in a direction perpendicular to the first direction, and
- the plurality of battery cells are stacked in the housing space along the direction in which the plurality of electrode plates are stacked.
A method of manufacturing a battery cell, comprising:
- disposing a cap assembly comprising a current collector electrically connected to a foil on both sides of an electrode assembly in which a plurality of electrode plates are stacked and the foil protrudes to both sides, and connecting the cap assembly to both sides of the electrode assembly;
- and
- covering an exposed surface of the electrode assembly exposed from the cap assembly with a case to house the electrode assembly.
