Description
Technical field
The utility model relates to battery technology fields, and in particular to a kind of soft package lithium battery airbag.
Background technique
After soft package lithium battery drying now, it is related to fluid injection, chemical conversion, pumping envelope, partial volume eventually.It is reserved to dry battery core
Airbag, battery core produces gas after chemical conversion, and airbag is melted into as storage to be produced the space of gas and exist.
Currently, positive and negative electrode material gram volume constantly upgrades, the additive types of required electrolyte are various, the production gas of chemical conversion
Amount is also more and more, so required airbag is also increasing.Simultaneously as chemical conversion yield generally occurs in 3.5V or so, and change
At final voltage be much higher than 3.5V, thus Battery formation be likely to require two steps chemical conversion.The increase of airbag and two steps are melted into nothing
It is doubtful to greatly increase manufacturing cost and slow down production efficiency.
Utility model content
The utility model to solve the above-mentioned problems, to provide a kind of soft package lithium battery airbag.
In order to achieve the above objectives, the technical solution of the utility model is as follows:
A kind of soft package lithium battery airbag, the soft package lithium battery airbag include:
Airbag ontology is respectively equipped with sequentially connected first heat-sealing on the inside of described airbag ontology or so side and bottom side
The inside of layer, the top side side of the airbag ontology is equipped with the second hot sealing layer, and second hot sealing layer is connect with the first hot sealing layer, and
The length of second hot sealing layer is less than the length on airbag ontology top side side, not set second hot sealing layer on the side of airbag ontology top side
Position be equipped with liquid injection port；
Conduit, the conduit are connected to airbag ontology, and are connect with the second hot sealing layer；
Sealing element, the sealing element are removably disposed on conduit.
In a preferred embodiment of the utility model, the conduit is metal catheter or polymeric catheter.
In a preferred embodiment of the utility model, the diameter of conduit is 1-5mm.
The beneficial effects of the utility model are:
The utility model can realize that a step is melted into soft package lithium battery, greatly improve production efficiency and saved manufacturing cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1, soft package lithium battery airbag provided by the utility model comprising airbag ontology 100, conduit 200 and close
Sealing 300.
Airbag ontology 100 be rectangle, to the left the inside on side 110, right edge 120 and bottom side 130 be respectively equipped with according to
First hot sealing layer 400 of secondary connection is equipped with the second hot sealing layer 500, and the second hot sealing layer 500 in the inside on its top side side 140
It can be connect with the first hot sealing layer 400 on left side 110 or right edge 120.
Wherein, the whole covering of the first hot sealing layer 400 in left side 110, right edge 120 and bottom side 130, and top side side
The not whole covering of the second hot sealing layer 500 on 140, length is less than the length on top side side, not set second on top side side 140
The position of hot sealing layer 500 is equipped with liquid injection port 150, consequently facilitating fluid injection.
By liquid injection port 150 can to formed in airbag ontology 100 with the battery core 600 of 100 integrally connected of airbag ontology into
Then row fluid injection seals seal liquid injection port 150, can be with the first hot sealing layer in left side 110, right edge 120 and bottom side 130
400, which form airbag ontology with the second hot sealing layer 500 on top side side 140, completely seals seal.
Conduit 200 is specially metal catheter or polymeric catheter, and diameter 1-5mm is connected to airbag ontology 100,
And connect with the second hot sealing layer 500, be for connecting external vaccum-pumping equipment, external vaccum-pumping equipment by conduit 200 and
When exclude in airbag ontology 100 generated gas, 600 internal vacuum of Balance route battery core in battery core 600.
Sealing element 300 is removably disposed at the nozzle of conduit 200, be for conduit 200 to be sealed,
When conduit 200 is not connect with external vaccum-pumping equipment, may be provided at the nozzle of conduit 200.
The concretely vacuum stopper of sealing element 300.
In addition, length a is the plastic-aluminum film length that battery core 600 is arrived on top side side 140 in figure, traditional definition is airbag length, with
Top side side 140 forms traditional airbag, for accommodating generated gas in battery core 600, and the reality that the application passes through above structure
It applies, plastic-aluminum film length a, a value range that the application is substantially shorter top side side 140 to battery core 600 is 0-3cm, so significantly
Reduce manufacturing cost.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
