Abstract
The invention discloses explosion-proof equipment of lithium battery.Structure including lithium battery casing, positive electrode, negative electrode, sheet rubber, it is characterised in that：Lithium battery casing is provided with passage；Covered on passage and be fixed with sheet rubber, the thickness of sheet rubber is 0.5 5mm.Due to, as explosion-proof valve, injecting electrolyte and nitrogen into battery using sheet rubber without opening up liquid injection hole in addition, liquid injection hole and explosion-proof valve be integrated, simple in construction, cost is low, easy to process simple to operate；In use, only need to inwardly inject electrolyte and nitrogen through sheet rubber with needle tubing, after extracting syringe needle, using the enclosed elastic pin hole of sheet rubber, reach electrolyte and nitrogen does not leak, lithium battery normal work.Suitable for variously-shaped and different-thickness lithium battery.
Description
Technical field
Explosion-proof equipment of lithium battery of the present invention, it is related to the technical field of lithium battery, applied to the explosion-proof of lithium battery.
Background technology
Lithium battery is extensive due to having the advantages that in light weight, small volume, capacitance are larger, charging rate is very fast
Applied in various products, including on household electrical appliance and electric car.
But heating, burning or even the phenomenon exploded usually occurs in lithium battery in use, directly
The life security of people is compromised, the lighter influences main frame and used, and severe one can also burn main frame and cause fire.It is reported that day
Family fire accident caused by more cause lithium battery burns has occurred in this in recent years.
In order to avoid such dangerous generation, on the basis of air-filled pore, explosion-protection equipment is additionally arranged in addition, due to anti-
Quick-fried device it is complicated, difficulty of processing is big, accordingly adds production cost；Also have plenty of and used on blast resistance construction
The pit thinner than original housing is processed on housing, is directly used in explosion-proof, or through hole is machined to, using the side of welding
Formula is capped metal foil on through hole, as explosion-proof and sealing, the technical requirements welded together due to housing with metal foil
Height, so welding index is difficult control, explosion-proof effect is extremely unstable.
The content of the invention
It is an object of the invention to overcome drawbacks described above, explore and a kind of merge topping up, air-filled pore and explosion-protection equipment
Structure, designs that a kind of technique is simple, cost is low, easy to operate explosion-proof equipment of lithium battery.What its technology was realized in
：Structure including lithium battery casing, positive electrode, negative electrode, sheet rubber, it is characterised in that：Lithium battery casing
It is provided with passage；Covered on passage and be fixed with sheet rubber, the thickness of sheet rubber is 0.5-5mm.Implement the technology
Obvious advantage and effect be：Due to, as explosion-proof valve, being injected using sheet rubber without opening up liquid injection hole in addition into battery
Electrolyte and nitrogen, liquid injection hole and explosion-proof valve are integrated, simple in construction, and cost is low, easy to process simple to operate；
In use, only need to inwardly inject electrolyte and nitrogen through sheet rubber with needle tubing, after extracting syringe needle, the bullet of sheet rubber is utilized
Property encloses pin hole, and reaching electrolyte and nitrogen does not leak, lithium battery normal work；And when cell internal pressure it is excessive,
When overloading, gas will strut the aperture left during fluid injection and outwards discharge, and can be by changing the thickness of sheet rubber
It is thin with for injecting the syringe needle size of electrolyte to control the discharge capacity of lithium battery interior pressure, suitable for variously-shaped and not
The lithium battery of stack pile.
Brief description of the drawings
Fig. 1 is the main structure diagram of the embodiment of the present invention；
Wherein：1- positive electrodes, 2- sheet rubbers, 3- passages, 4- negative electrodes, 5- lithium battery casings.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described：
See accompanying drawing 1, lithium battery casing (5) top is provided with positive electrode (1), negative electrode (4).Positive electrode (1) and negative electricity
Passage (3) is provided between pole (4), sheet rubber (2) is fixed with passage (3).
See accompanying drawing 1, lithium battery casing (5) top is provided with positive electrode (1), negative electrode (4).Positive electrode (1) and
Passage (3) is provided between negative electrode (4), sheet rubber (2) is fixed with passage (3).
In use, being inoculated with the needle tubing of liquid, noted by syringe needle through sheet rubber (2) to lithium battery casing (5) is interior
Penetrate electrolyte and nitrogen, after extracting syringe needle, using the enclosed elastic pin hole of sheet rubber (2), reach electrolyte and nitrogen
Gas does not leak, lithium battery normal work.
When lithium battery interior pressure exceedes pressure-resistant setting, gas passes through passage (3), by sheet rubber (2)
Pin hole carry out pressure release, lithium battery interior pressure is no more than pressure-resistant setting.Lithium battery is effectively prevented to be pressed due to inside
Blast caused by power is excessive.
Claims (2)
1. explosion-proof equipment of lithium battery, the structure including lithium battery casing, positive electrode, negative electrode, sheet rubber, its feature exist
In：Lithium battery casing is provided with passage；Covered on passage and be fixed with sheet rubber.
2. according to the simple explosion-proof equipment of lithium battery described in claim 1, it is characterised in that：The thickness of described sheet rubber is
0.5-5mm。
