Abstract
The utility model discloses a lithium ion battery which comprises a negative electrode and a positive electrode which are arranged in the lithium ion battery, a diaphragm arranged between the negative electrode and the positive electrod, a first electrode tab connected with the positive electrode, and a second electrode tab connected with the positive electrode, wherein the thickness of the first electrode tab is 50 to 100 mu m; and the thickness of the second electrode tab is 50 to 100 mu m. The lithium ion battery has the beneficial effects that the two electrode tabs are relatively high in flexibility and occupy a relatively small space due to proper thicknesses of the two electrode tabs; and therefore, the space occupied by the whole lithium ion battery is effectively reduced.
Description
[technical field]
The utility model relates to a kind of lithium ion battery.
[background technology]
Existing lithium ion battery, the thickness of its lug or thicker takies larger space, makes the volume of whole lithium ion battery larger; The thickness of lug is less, although reduced the volume of lithium ion battery, the pliability of lug is relatively poor.
[utility model content]
In order to overcome the deficiencies in the prior art, the utility model provides a kind of lithium ion battery, with in the flexible while that guarantees the electrode ear, can effectively reduce whole lithium ion battery shared space.
A kind of lithium ion battery, comprise the positive electrode, negative electrode and the barrier film between positive electrode and negative electrode that are arranged in lithium ion battery, also comprise the first electrode ear that is connected with negative electrode and the second electrode ear that is connected with positive electrode, the thickness of the first electrode ear is between 50um to 100um, and the thickness of the second electrode ear is between 50um to 100um.
Preferably, the thickness of described the first electrode ear is between 70um to 80um, and the thickness of described the second electrode ear is between 70um to 80um.
Preferably, the thickness of described the first electrode ear is 70um, and the thickness of described the second electrode ear is 70um.
The beneficial effects of the utility model are: the thickness of the setting of two electrode ears makes two electrode ears possess the flexible while preferably, and the shared space of two electrode ears is less, thereby effectively reduces the size that whole lithium ion battery takes up space.
[description of drawings]
Fig. 1 is the generalized section of the lithium ion battery of a kind of embodiment of the utility model.
[embodiment]
Below with reference to accompanying drawing, specific embodiment of the utility model is described in further detail.
A kind of lithium ion battery 6, comprise the positive electrode 1, negative electrode 3 and the barrier film 2 between positive electrode 1 and negative electrode 3 that are arranged in battery 6, also comprise the first electrode ear 4 that is connected with negative electrode 3 and the second electrode ear 5 that is connected with positive electrode 1, the thickness of the first electrode ear 4 is between 50um to 100um, and the thickness of the second electrode ear 5 is between 50um to 100um.
Preferably, the thickness of described the first electrode ear 4 is between 70 to 80um, and the thickness of described the second electrode ear 5 is between 70 to 80um.
Preferably, the thickness of described the first electrode ear 4 is 70um, and the thickness of described the second electrode ear 5 is 70um, like this, in the flexible while that guarantees two electrode ears, the shared space of two electrode ears is less, thereby effectively reduces the size that whole lithium ion battery 6 takes up space.
