Abstract
This utility model relates to a kind of cover plate of power lithium, it includes cover plate matrix, is inserted in the pole in the middle part of described cover plate matrix, is set on described pole and is close to the felt pad on described cover plate matrix two surface and be set on described pole and be close to the electrode pressing plate of described felt pad, described pole end face offers its internal screw extended oriented, described cover plate matrix is embedded with at least one explosion-proof valve, and described explosion-proof valve is the nickel thin slice being welded on described cover plate matrix.By the explosion-proof valve being embedded in cover plate matrix being used the nickel thin slice being welded on cover plate matrix, so can not improve the explosion-proof capabilities of lithium battery cover plate, thus improving the security performance of lithium ion battery.
Description
Technical field
This utility model belongs to field of lithium, relates to a kind of cover plate, is specifically related to a kind of cover plate of power lithium.
Background technology
Lithium battery has the advantages such as voltage height, life-span length, energy density are high, light, and its application is also constantly expanding,
But its safety is poorer than other secondary cells, when dynamic lithium battery overcharges, the material such as its electrolyte inside can crack product
Angry body so that battery case blow-up ruptures, and allows oxygen enter with the lithium ion being deposited in negative terminal surface and reacts, and then occurs quick-fried
Fried.
Power lithium-ion battery is the power supply providing power resources, refers to as electric automobile, electric train, electrical salf-walking more
Car, golf cart provide the accumulator of power.Electrokinetic cell typically uses aluminum hull to encapsulate, and has that volume is little, lightweight, electricity
By force, the feature such as memoryless and environmental protection, be the most widely used.Owing to power lithium-ion battery is at battery cover board
For sealing structure after welding with aluminum hull, when battery is short-circuited, air pressure inside can increase rapidly, is susceptible to battery explosion
Dangerous.
Summary of the invention
This utility model purpose is to provide a kind of cover plate of power lithium to overcome the deficiencies in the prior art.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of cover plate of power lithium, and it includes lid
Board substrate, it is inserted in the pole in the middle part of described cover plate matrix, is set on described pole and is close to described cover plate matrix two surface
Felt pad and be set on described pole and be close to the electrode pressing plate of described felt pad, described pole end face offer oriented its
The internal screw extended, described cover plate matrix is embedded with at least one explosion-proof valve, and described explosion-proof valve is for being welded on described cover plate base
Nickel thin slice on body.
Optimally, the edge of described cover plate matrix has been wholely set clamping projection.
Optimally, described cover plate matrix includes being connected with described felt pad and perpendicular with described pole axial line
One horizontal part, be arranged on outside described first horizontal part and second horizontal part perpendicular with described pole axial line and with institute
State the first horizontal part and described second horizontal part one connection and the connecting portion paralleled with described pole axial line.
Further, described explosion-proof valve is embedded in described second horizontal part.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that this utility model
Cover plate of power lithium, by the explosion-proof valve being embedded in cover plate matrix being used the nickel thin slice being welded on cover plate matrix,
So can not improve the explosion-proof capabilities of lithium battery cover plate, thus improve the security performance of lithium ion battery.

Detailed description of the invention
This utility model is further described by the embodiment shown in below in conjunction with the accompanying drawings.
Cover plate of power lithium as shown in Figure 1, mainly includes cover plate matrix 1, pole 2, felt pad 3 and electrode pressing plate 4
Deng.
Wherein, pole 2 is plugged in the middle part of cover plate matrix 1, and its end face (end face of lithium battery body dorsad) offers
To its internal screw 21 extended.Felt pad 3 is set on pole 2 and is close to two surface up and down of cover plate matrix 1, electrode pressing plate
4 are set on pole 2, and it is close to the surface of felt pad 3.At least one explosion-proof valve 11, this explosion-proof valve it is embedded with in cover plate matrix 1
11 is the nickel thin slice being welded on cover plate matrix 1.
In the present embodiment, the edge of cover plate matrix 1 has been wholely set clamping projection 12, such that it is able to lithium battery originally
Body carries out location engaging；Stage portion can also be formed at the end face of pole 2 lithium battery body dorsad.Cover plate matrix 1 include with absolutely
Edge pad 3 is connected and first horizontal part 13 perpendicular with pole 2 axial line, is arranged on outside the first horizontal part 13 and and pole
The second horizontal part 14 that 2 axial lines are perpendicular and be connected with the first horizontal part 13 and the second horizontal part 14 one and with pole 2
The connecting portion 15 that axial line is parallel.Explosion-proof valve 11 is embedded in the second horizontal part 14.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All according to this utility model spirit made equivalence change or modify, all should contain protection domain of the present utility model it
In.
