Abstract
The utility model discloses an electrode tab for lithium ion batteries, which can improve safety performance of the lithium ion batteries and prolong service life of the lithium ion batteries. The electrode tab for lithium ion batteries comprises an electrode tab substrate (1) and electrode tab gum (2) which is heat-sealed on the electrode tab substrate (1). The upper end of the electrode tab substrate (1) is in cylinder shape, and the lower end of the electrode tab substrate is in flat shape, thereby being easy to be inserted into a disc-shaped lithium ion battery so as to be connected with a positive pole or a negative pole. The electrode tab gum (2) is heat-sealed on a cylinder-shaped portion of the electrode tab substrate (1). The electrode tab for lithium ion batteries can be widely applied to the field of manufacture of the lithium ion batteries.
Description
Technical field
The utility model relates to a kind of lithium ion battery lug.
Background technology
At present, the lug that flexible package lithium cell uses is the sheet metal of sheet, because Metal Flake lug is extremely thin, cross-sectional area is very little, cause lithium battery current density by lug in charge and discharge process very big, thereby heating causes internal temperature of battery to raise easily, breaks through heat-sealing place of aluminum plastic film easily, leaks, especially during multiplying power discharging, the thermal effect highly significant of lithium battery causes the security performance of lithium battery to descend, and this just exists certain weak point.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of and can improve the security performance of lithium battery, the lithium ion battery lug that prolongs the useful life of lithium battery.
The technical scheme that the utility model adopted is: the utility model comprises lug matrix and the lug glue of heat-sealing on described lug matrix, the upper end of described lug matrix is cylindric, the lower end is flat and is convenient to insert the video disc lithium battery interior, be connected described lug glue heat-sealing cylindrical position on described lug matrix with positive pole or negative pole.
The beneficial effects of the utility model are: because the utility model comprises lug matrix and the lug glue of heat-sealing on described lug matrix, the upper end of described lug matrix is cylindric, the lower end is flat and is convenient to insert the video disc lithium battery interior, be connected with positive pole or negative pole, described lug glue heat-sealing cylindrical position on described lug matrix, the upper end cross-sectional area of cylindrical described lug matrix is much larger than the sheet lug, can effectively reduce lithium battery current density by lug in charge and discharge process, significantly reduce the thermal effect in the battery charge and discharge process, avoid the generation revealed, so the utility model can improve the security performance of lithium battery, prolong the useful life of lithium battery.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises lug matrix 1 and the lug glue 2 of heat-sealing on described lug matrix 1, the upper end of described lug matrix 1 is cylindric, the lower end is flat and is convenient to insert the video disc lithium battery interior, be connected described lug glue 2 heat-sealing cylindrical positions on described lug matrix 1 with positive pole or negative pole.
With the anode ear is example: at first choose a cylindric aluminum strip, one end of cylindric aluminum strip is made flat, described lug glue 2 is heat sealed to makes anode ear on the aluminum strip, with this anode ear lithium battery of packing into, the battery that side seal is good carries out closedtop, aluminum-plastic composite membrane and anode ear are at 190 ℃, 0.2MPa pressure sealed for 2 seconds down, the peel strength that detects heat-sealing place is 70N/15mm, discharge and recharge test, after charging is finished, the surface temperature of battery rises 0.5 ℃, the lithium battery that is full of electricity is at room temperature carried out discharge test, select the 1C discharge, after discharge finishes, the surface temperature of battery rises 1.2 ℃, and the thermal effect of the utility model lithium battery is significantly less than the battery of sheet lug; This anode ear is resisted bent rich test, and the rich number of times of the song of the utility model anode ear is 23 times, is 8 times and adopt the rich number of times of song of same material anode ear in the form of sheets, has obviously improved the rich performance of anti-song of lithium battery pole ear, has prolonged the useful life of battery.The principle of negative electrode lug is identical with anode ear, just tells no longer one by one at this.
The utility model can be widely used in the manufacturing field of lithium battery.
Claims (1)
1. lithium ion battery lug, it comprises lug matrix (1) and the lug glue (2) of heat-sealing on described lug matrix (1), it is characterized in that: the upper end of described lug matrix (1) is cylindric, the lower end is flat and is convenient to insert the video disc lithium battery interior, be connected with positive pole or negative pole, described lug glue (2) heat-sealing is gone up cylindrical position at described lug matrix (1).
