Abstract
The utility model provides a connecting structure of an electrode tab and a battery chip of a flexibly packaged lithium ion battery. The connecting structure of the electrode tab and the battery chip of the flexibly packaged lithium ion battery comprises the battery chip, the electrode tab and high-temperature gummed paper. The electrode tab forms a welding part and a folding part after being folded for 180 degrees, the folding part is longer than the welding part, the welding part is welded on the battery chip, and the high-temperature gummed paper is arranged between the battery chip and the welding part. The connecting structure of the electrode tab and the battery chip of the flexibly packaged lithium ion battery has the advantages of being capable of effectively reducing the area of the cover head of the battery, accordingly enabling the size of the whole battery to be reduced and improving the volume energy ratio of the battery.
Description
Technical field
The utility model relates to lithium ion battery, relates in particular to a kind of lug and battery chip syndeton of flexible packing lithium ion battery.
Background technology
Lithium ion battery within short decades, has obtained developing rapidly since last century, the nineties exploitation was come out.Therefore the advantages such as and that flexible packing lithium ion battery has energy density is high, and cycle life is good, shape is changeable enjoy favor.Existingly in the industry the relay-type welding is adopted in the welding of flexible packing lithium ion battery Multilayer pole ear, after adopting the relay-type welding, between lug and battery chip, the space is larger, can cause whole battery dead volume excessive.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of lug and battery chip syndeton of flexible packing lithium ion battery.
The utility model provides a kind of lug and battery chip syndeton of flexible packing lithium ion battery, comprise battery chip, lug, high tempreture tape, described lug forms weld part and folding part after 180 degree doublings, described folding part is than described welding minister, described weld part is welded on described battery chip, and described high tempreture tape is between described battery chip and described weld part.
As further improvement of the utility model, described high tempreture tape thickness is between 10mm to 20mm.
As further improvement of the utility model, described high tempreture tape thickness is 15mm.
The beneficial effects of the utility model are: the utility model can effectively reduce the area of battery closedtop, thereby the volume of whole battery is reduced, and improves the volume energy ratio of battery.
Description of drawings
Fig. 1 is the structural representation of lug of the present utility model when folding.
Fig. 2 is the structural representation of lug of the present utility model after folding.
Fig. 3 is the structural representation of tab welding of the present utility model on battery chip, and wherein lug is not folding.
Fig. 4 is the structural representation of tab welding of the present utility model on battery chip, and wherein lug is through folding.
Embodiment
As shown in Figures 1 to 4, the utility model discloses a kind of lug and battery chip syndeton of flexible packing lithium ion battery, comprise battery chip 1, lug 2, high tempreture tape, described lug 2 forms weld part 21 and folding part 22 after 180 degree doublings, described folding part 22 is longer than described weld part 21, described weld part 21 is welded on described battery chip 1, and described high tempreture tape is between described battery chip 1 and described weld part 21.
Between described battery chip 1 and described weld part 21, avoid lug 2 directly to be connected with battery chip 1 because of high tempreture tape, prevent short circuit.
As an embodiment of the present utility model, described high tempreture tape thickness is between 10mm to 20mm.
As further improvement of the utility model, described high tempreture tape thickness is 15mm.
The utility model can effectively reduce the area of battery closedtop, thereby the volume of whole battery is reduced, and improves the volume energy ratio of battery.
The computational methods of battery effective volume are: the width of battery takes advantage of the thickness of battery to take advantage of the height of battery again, and wherein the height of battery is to add the height of utmost point group with the height of the following closedtop of tab.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
