Description
Technical field
The utility model relates to technical field of lithium ion more particularly to a kind of lithium-ion battery shells.
Background technique
Lithium battery has become portable due to the advantages that its is light-weight, small in size, charging rate is fast and capacitance is big
The preferred battery of electronic product, lithium battery capacity density is high, price is competitive, it is contemplated that and the coming years will be the market mainstream,
But lithium battery but hides always the danger of explosion, overcharges in lithium battery, over-discharge or when internal short-circuit easily lead to operating current
Excessive, internal temperature of battery gradually rises, and generates the gas of high temperature and pressure and expands, the pressure and temperature inside battery case
When the range that can bear more than shell, shell is easily burst, and is caused internal flammable and explosive substance to leak, is further caused quick-fried
The serious accidents such as fried or fire, not can guarantee the safety used.
It would therefore be desirable to seek the new technology of one kind to solve above-mentioned technical proposal.
Utility model content
The purpose of utility model is: in view of the above deficiencies, providing a kind of lithium-ion battery shell.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
A kind of lithium-ion battery shell, including enclosure body, the enclosure body inner wall are equipped with heat-sink shell, the heat-sink shell
It is externally provided with heat dissipating layer, it is the reinforcement shell of enclosure body outside the heat dissipation cavity that the heat dissipating layer, which is externally provided with heat dissipation cavity, described
Explosion-proof upper cover is connected by sealing ring in enclosure body.
The explosion-proof upper cover includes welding piece, and explosion rupture disk is connected on the welding piece, is connected in the explosion rupture disk
Lid, forms explosion-proof cavity between the explosion rupture disk and upper cover.
The explosion rupture disk is equipped with bursting membrane layer.
The enclosure body bottom is equipped with pressure release film.
Compared with prior art, the utility model is achieved has the technical effect that enclosure body inner wall passes through heat-sink shell, dissipates
Thermosphere, heat dissipation cavity are constituted, and strengthen its heat sinking function；And enclosure body outer wall is to reinforce shell, improves enclosure body
Intensity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment one.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
Embodiment one:
As described in Figure 1, a kind of lithium-ion battery shell of the utility model, including enclosure body 1, the enclosure body 1
Inner wall is equipped with heat-sink shell 2, and the heat-sink shell 2 is externally provided with heat dissipating layer 3, and the heat dissipating layer 3 is externally provided with heat dissipation cavity 4, the heat dissipation
It is the reinforcement shell 5 of enclosure body 1 outside cavity 4, passes through sealing ring 6 in the enclosure body 1 and connect explosion-proof upper cover 7.
The explosion-proof upper cover 7 includes welding piece 8, is connected with explosion rupture disk 9 on the welding piece 8, connects in the explosion rupture disk 9
There is upper cover 10, forms explosion-proof cavity 11 between the explosion rupture disk 9 and upper cover 10.
The explosion rupture disk 9 is equipped with bursting membrane layer 12.
1 bottom of enclosure body is equipped with pressure release film 13.
Compared with prior art, the utility model it is achieved have the technical effect that 1 inner wall of enclosure body by heat-sink shell 2,
Heat dissipating layer 3, heat dissipation cavity 4 are constituted, and strengthen its heat sinking function；And 1 outer wall of enclosure body is to reinforce shell 5, improves shell
The intensity of ontology 1.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
