Definitions
- the internal resistance of the battery cell can be reduced by forming each electrode tab on the top and bottom of the electrode assembly to increase the area of the electrode tab.
- the ratio of the total height of the jelly roll to the total height of the battery can be increased, thereby increasing the energy density of the cylindrical battery cell.
- FIG. 11 is a view showing a vehicle according to an embodiment of the present invention.
- the second electrode includes a second electrode current collector and a second electrode active material coated on one or both surfaces of the second electrode current collector.
- An uncoated portion to which the second electrode active material is not coated exists at the other end of the second electrode current collector in the width direction (direction parallel to the Z-axis).
- the uncoated portion functions as the second electrode tab 12 .
- the second electrode tab 12 is provided below the jelly roll 10 accommodated in the battery can 20 in the vertical direction (direction parallel to the Z-axis).
- the first current collecting plate 30 is coupled to the first electrode tab 11 on top of the jelly roll 10 .
- a lead L made of a conductive metal material may be connected to the first current collecting plate 30 .
- the lead L extends upward of the jelly roll 10 and may be directly coupled to the top cap 60 or coupled to the connection plate 80 coupled to the lower surface of the top cap 60.
- a cylindrical battery cell 1 includes an insulating shrink tube 50 .
- the insulating shrink tube 50 may include a shrinkable material. Therefore, when the insulating shrink tube 50 is shrunk after wrapping the jelly roll 10 and the first current collector plate 30 with the insulating shrink tube 50, the insulating shrink tube 50 wraps the jelly roll 10 and the first collector plate 30. 1 may be tightly fixed to the current collecting plate 30 . In this way, insulation can be ensured reliably.
- the insulating shrinkable tube 50 may include a material having heat shrinkability that shrinks when heat is applied.
- the insulating shrink tube 50 may include polyethylene terephthalate (PET) having heat shrinkability.
- PET polyethylene terephthalate
- the material of the insulating shrink tube 50 is not limited thereto, and any material that can be shrunk without losing insulation by heat can be employed for the insulating shrink tube 50 of the present invention.
- the insulating shrink tube 50 may be shrunk by heat within a predetermined temperature range.
- the predetermined temperature range may be a temperature range including a temperature range generally formed by heat generated inside the secondary battery during charging and discharging of the secondary battery.
- the ease of injection of the electrolyte and the impregnability can be improved.
- the diameter of the first current collecting plate 30 is smaller than the diameter of the jelly roll 10
- the battery can 20 and the battery can 20 are indented due to the formation of the beading portion 21.
- Concern about contact between the first current collecting plates 30 may be eliminated. Therefore, in this case, the total height of the jelly roll 10 can be increased in the battery can 20, and thus the energy density can be improved.
- a difference between the radius R10 of the jelly roll 10 and the radius R30 of the first current collecting plate 30 may be equal to or greater than, for example, the pressing depth of the beading portion 21. .
- the first length T1 may be longer than the second length T2. At least a portion of the second area A2 may be located below the beading portion 21 formed in the battery can 20 .
- the first current collecting plate 30 may cover the first area A1 of the jelly roll 10 . That is, the diameter of the first current collecting plate 30 may be substantially equal to the length of the first area A1 in the radial direction.
- the radius of the first collector plate 30 is the distance from the center C of the jelly roll 10 to the boundary between the first area A1 and the second area A2. It may also be configured smaller.
- the first electrode tab 11 located in the second area A2 of FIG. 8 may be deleted. This is shown in detail in FIG. 9 .
- the jelly roll 10 does not include the first electrode tab 11 in the second area A2.
- the total height of the jelly roll 10 can be further increased compared to the embodiment shown in FIG. 8 .
- the dead space inside the battery can 20 may be further reduced compared to FIG. 8 . Therefore, the energy density of the battery can be maximized.
- the top cap 60 may include a protruding portion 61 protruding upward from the center thereof. That is, the protruding portion 61 may protrude upward to facilitate contact with an electrical connection component such as a bus bar.
- the cylindrical battery cell 1 may further include a connection plate 80 .
- FIG. 11 is a diagram for explaining a vehicle including the battery pack of FIG. 10 .
