Description
Technical field
The utility model is related to field of lithium, more particularly to a kind of protective case for lithium-sulfur cell lug.
Background technology
With the development of modern society, the application of lithium battery is more and more extensive.Wherein, since lithium-sulfur cell is with higher
Energy density is a kind of very promising lithium battery.Lithium battery is generally divided into positive plate, negative plate, diaphragm, electrolyte four
Part.Wherein, positive plate include aluminium foil make plus plate current-collecting body and load positive active material positive plate constitute, cathode by
The negative plate of negative current collector and load negative electrode active material that copper foil makes is constituted.It is formed after positive and negative anodes collector is welded
Positive and negative lug.Positive and negative anodes lug, due to its lower intensity, is easy bending, damaged, Er Qiezheng in welded about subsequent process
Negative lug contact is easy to happen short circuit, influences cell safety.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of protective cases for lithium-sulfur cell lug, to protect pole
Ear is not bent, is damaged, and positive and negative anodes lug is avoided to contact.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of protective case for lithium-sulfur cell lug, the protective case is by the first film and second using hard material
Film is constituted, the accommodation space for being used for placing battery lug with one between the first film and second film, described
The length of the first film is not more than the length of the battery pole ear, and the length of second film is more than the length of the first film
Degree, second film have a first end and a second end in the longitudinal direction, and the first film is fixed on close to described first
The position at end, wherein the second end be more than the first film predetermined length, the first film in the direction of the width two
A side of side edge and the close first end with second film along connecting respectively, and the first film is close to described
A side edge of second end is opening.
Preferably, the first film and second film are insulating materials.
Preferably, the first film and second film are high-temperature polyester film.
Preferably, the first film is fixedly connected with second film by high temperature gummed tape.
Preferably, the length of the first film is equal to the length of the battery pole ear.
Preferably, the predetermined length is not less than the distance between the root of the battery pole ear and described battery body.
Compared with prior art, the beneficial effects of the utility model are：The hard material of protective case, can protect lug to exist
It is not bent, damages in next process.Moreover, the insulating property (properties) of protective case, avoids positive and negative anodes lug and be in contact and lead
Short circuit is caused, to improve the safety of battery.
Description of the drawings
Some specific realities of the utility model are described in detail by way of example rather than limitation with reference to the accompanying drawings hereinafter
Apply example.Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing：
Fig. 1 is a kind of schematic diagram of protective case for lithium-sulfur cell lug of the utility model；
Fig. 2 uses schematic diagram for a kind of protective case for lithium-sulfur cell lug of the utility model.
The meaning of each symbolic indication is as follows in figure：
1- the first films；The second films of 2-；21- first ends；22- second ends；3- battery pole ears.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As depicted in figs. 1 and 2, the utility model is used for the protective case of lithium-sulfur cell lug 3, mainly by using hard material
The first film 1 of material and the second film 2 are constituted.The first film 1 and second film 2 are insulating materials.In this implementation
In example, the first film 1 and second film 2 are high-temperature polyester film.The first film 1 and second film 2
Between with one be used for placing battery lug 3 accommodation space.
Second film 2 has first end 21 and second end 22 in the longitudinal direction.The first film 1, which is fixed on, to be leaned on
The position of the nearly first end 21.And the second end 22 of the second film 2 is more than 1 predetermined length of the first film.Described first
The two sides in the direction of the width of film 1 along and close to the first end 21 a side along respectively with second film 2
Connection, the first film 1 are opening close to a side edge of the second end 22.That is, lug can from be open into
Enter in accommodation space, and is protected by the accommodation space that three side sealing closes.The first film 1 and second film 2 pass through height
Warm adhesive tape is fixedly connected, i.e. the three of the first film 1 edge and 2 corresponding edge of the second film can mutually be sticked by high temperature gummed tape
Even.
In order to accommodate lower lug, the length of the first film 1 is not more than the length of the battery pole ear 3.In this implementation
In example, the length of the first film 1 is equal to the length of the battery pole ear 3.The length of second film 2 is more than described the
The length of one film 1.Since the root of lug is the most weak place of intensity, the second end 22 of the first film 1 is more than first
The predetermined length of film 1 is not less than the distance between the root of the battery pole ear 3 and described battery body, so that hard
Second film 2 made of material can protect lug not to be bent, be damaged.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
