Abstract
The utility model discloses a cylindrical lithium ion battery, which comprises a cylindrical shell, a cap connected above the shell and a battery jellyroll installed in the shell. An anode tab and a cathode tab are arranged on the battery jellyroll. The shell and the cap are made of aluminum. The anode tab is welded on the cap. A cathode output end is arranged on the cap. The cathode tab is welded on the cathode output end. The cap is welded on the shell. The utility model has the advantages that the manufacturing cost of the battery is reduced, the dead weight of the battery is reduced, the use is facilitated and the sealing performance of the battery is greatly improved.
Description
Technical field
The utility model relates to battery manufacturing technology field, is specifically related to a kind of column lithium ion battery.
Background technology
Lithium ion battery is owing to have advantages such as in light weight, that volume is little, capacitance is big, charging rate is fast, is widely used on the vehicles such as all kinds of numbers, communication product and electric bicycle, electric automobile such as notebook computer.
Traditional column lithium ion battery shell is generally stainless steel casing, and whole housing is as negative pole, and the block terminal is as positive pole, and stainless steel casing can effectively prevent the corrosion of electrolyte because of having corrosion resistance.Yet the price of stainless steel material is higher and density is bigger, and when being applied to the battery pack of big capacity large volume, not only cost of manufacture is higher, makes that also the weight of battery pack itself is bigger, is unfavorable for using.And with battery cap and housing seal, sealing property is low, occurs the problem of battery leakage easily by slot rolling, mechanical sealing process for traditional lithium ion battery.
The utility model content
Technical problem to be solved in the utility model provides a kind of column lithium ion battery, has not only reduced the battery cost of manufacture, has alleviated the battery own wt, is beneficial to use more, and has improved the sealing property of battery greatly.
For solving the problems of the technologies described above, the technical solution of the utility model is: column lithium ion battery, comprise cylindrical housings, be connected in the block of described housing top and be installed on the interior battery roll core of described housing, described battery roll core is provided with positive pole ear and negative lug, described housing and described block are aluminum hull, described positive pole ear is welded on the described block, and described block is provided with cathode output end, and described negative lug is welded on the described cathode output end.
As a kind of optimized technical scheme, described block is welded on the described housing.
After having adopted technique scheme, the beneficial effects of the utility model are: because the utility model housing and block adopt aluminum hull, not only greatly reduce the cost of manufacture of battery, and because the proportion of aluminium is than little many of stainless proportion, therefore column lithium ion battery of the present utility model is lighter than traditional cylindrical lithium ion battery weight, can use more easily.Because the positive pole ear material on the battery roll core is an aluminium, realizes that for the ease of welding procedure the utility model is connected the positive pole ear of battery roll core with aluminum cap, and negative lug is welded on the cathode output end on the battery cap.So, whole housing of the present utility model is anodal, and the terminal on the block becomes battery cathode.And, make the sealing of battery improve greatly because block of the present utility model is welded on the housing, overcome the drawback of the easy leakage of battery when machinery seals.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1. cylindrical housings, 2. block, 3. cathode output end, 4. negative lug, 5. positive pole ear, 6. battery roll core.
Embodiment
As shown in drawings, a kind of column lithium ion battery.This column lithium ion battery comprises cylindrical housings 1, be connected in the block 2 of housing 1 top and be installed on battery roll core 6 in the housing 1, and battery roll core 6 is provided with positive pole ear 5 and negative lug 4.Wherein, block 2 adopts and is laser-welded on the housing 1, makes the sealing of battery improve greatly, has overcome the drawback of the easy leakage of battery when machinery seals.
In addition, housing 1 of the present utility model and block 2 adopt aluminum hull to be made, not only greatly reduce the cost of manufacture of battery, and because the proportion of aluminium is than little many of stainless proportion, therefore column lithium ion battery of the present utility model is lighter than traditional cylindrical lithium ion battery weight, can use more easily.Because positive pole ear 5 materials on the battery roll core 6 are aluminium, realize that for the ease of welding procedure the utility model is connected the positive pole ear 5 of battery roll core 6 with aluminum cap 2, and negative lug 4 is welded on the cathode output end 3 on the battery cap 2.Therefore, whole housing 1 of the present utility model is anodal, and the cathode output end 3 on the block 2 becomes battery cathode.
Claims (2)
1. column lithium ion battery, comprise cylindrical housings, be connected in the block of described housing top and be installed on the interior battery roll core of described housing, described battery roll core is provided with positive pole ear and negative lug, it is characterized in that: described housing and described block are aluminum hull, described positive pole ear is welded on the described block, described block is provided with cathode output end, and described negative lug is welded on the described cathode output end.
2. column lithium ion battery as claimed in claim 1 is characterized in that: described block is welded on the described housing.
