Technical field
The present invention relates to a kind of polymer Li-ion battery, belong to technical field of lithium batteries.
Background technology
Polymer Li-ion battery have the advantages that it is higher than energy, recycle often, storage time it is long, not only just
Take such as mobile phone, DV and laptop computer on formula electronic equipment to be used widely, and be widely used in electricity
In terms of the big-and-middle-sized electrical equipment such as electrical automobile, electric bicycle and electric tool, therefore to the safety requirements of lithium ion battery
More and more higher.
Existing polymer lithium ion battery electric core is typically encapsulated in plastic-aluminum shell, because plastic-aluminum shell own material compares
It is soft, during the turnover and use of polymer Li-ion battery, the collision of battery body often occurs, falls problem, makes
It is damaged into the battery battery core in plastic-aluminum shell, influences the performance of polymer Li-ion battery, and larger potential safety hazard is present.
The content of the invention
To solve problems of the prior art, the invention provides one kind can efficiently protect battery battery core, safety
The good polymer Li-ion battery of performance.Concrete technical scheme is as follows：
A kind of polymer Li-ion battery, include the containment vessel of battery core body, packaging film and hollow structure, the packaging film bag
Wrap up in the battery core body to be placed in the containment vessel, some beams, institute are provided between the containment vessel and the packaging film
State beam and be provided with passage of the opening towards gap between the containment vessel and the packaging film, the containment vessel bottom is set
There is gas outlet, the containment vessel top is provided with seal protection layer, sealing layer is provided with above the seal protection layer.
As the improvement of above-mentioned technical proposal, the seal protection layer is quality of rubber materials.
As the improvement of above-mentioned technical proposal, the sealing layer is heat shrinkage film.
As the improvement of above-mentioned technical proposal, the battery core body upper end connection electrode lug, the electrode tabs are successively
Through the packaging film, seal protection layer and sealing layer.
As the improvement of above-mentioned technical proposal, the upper surface of the sealing layer flushes with the upper surface of containment vessel.
Beneficial effects of the present invention are：Packaging film is wrapped in battery core body and is placed on jointly in containment vessel, containment vessel and bag
Some beams are provided between dress film, can effectively prevent polymer Li-ion battery from vibrating or colliding in circular flow to cause
The damage of battery core body；Beam is provided with passage, and containment vessel bottom is provided with gas outlet, and any position of battery core body occurs swollen
, can be by the passage row pressure on beam when swollen, and the safe to use of battery finally ensure that by gas outlet pressure release.
Brief description of the drawings
Fig. 1 is a kind of structural representation of polymer Li-ion battery of the present invention.

The upper surface of the sealing layer 6 flushes with the upper surface of containment vessel 3, processing technology behaviour when facilitating the battery to process
Make.
When Inventive polymers lithium ion battery manufactures, containment vessel 3 is gone out by Mold Making first, and beam is pasted onto
It is stand-by in containment vessel 3, then using the parcel of packaging film 2 and packaging electric core body 1, after the completion of encapsulation, packaging film 2 will be enclosed with
Battery core body 1 is placed in the containment vessel 3 of shaping, and packaging film is close to beam during placement, then protects the sealing with through hole
Sheath 5 is placed on above packaging film, and hole size matches with electrode tabs 7, is advantageous to passing through for electrode tabs, finally places
Sealing layer 6 simultaneously fills colloid adhesive seal.
The polymer Li-ion battery of the present invention, packaging film are wrapped in battery core body and are placed on jointly in containment vessel, protect
Some beams are provided between shell and packaging film, can effectively prevent polymer Li-ion battery from vibrating or touching in circular flow
Hit the damage for causing battery core body；Beam is provided with passage, and containment vessel bottom is provided with gas outlet, any position of battery core body
, can be by the passage row pressure on beam when expanding, and the use peace of battery finally ensure that by gas outlet pressure release
Entirely.
Embodiments of the invention are described in detail above, but the content is only presently preferred embodiments of the present invention,
The practical range for limiting the present invention is not to be regarded as, all equivalent changes made according to the scope of the invention and improvement etc. all should
Still belong within covering scope of the present invention.
