Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Embodiment one
Fig. 1 is the structural representation of this utility model battery inner insulating layer embodiment；Fig. 2 is another structural representation of this utility model battery inner insulating layer embodiment；As depicted in figs. 1 and 2, the battery inner insulating layer of the present embodiment may include that hole 12, insulating barrier main body 11, pole location, rotating sheet insulation net 13 and screen cloth 14.
Wherein, insulating barrier main body 11 is strip slab structure, its shape is similar to coping plate 2 shape in battery, for the coping plate 2 in battery and battery core (not shown) are insulated, the size of insulating barrier main body 11 is not done concrete regulation by the present embodiment, is as the criterion with production application.The electric energy that battery core in battery produces is exported the outside of battery; by using pole 6 to realize; for making pole 6 can pass from insulating barrier main body 11; pole 6 can be carried out insulation protection again; battery inner insulating layer 1 is provided with hole 12, two pole location; and it being separately positioned on the two ends of insulating barrier main body 11, one of them is the hole 12, pole location of Positive Poles, and another be that the pole of negative pole pole positions hole 12.
In order to avoid rotating sheet 5 contacts with lug (not shown), (rotating sheet 5 is likely to contact with lug, positive and negative terminals is made to be electrically connected to form external short circuit), it is equipped with rotating sheet insulation net 13 in insulating barrier main body, and rotating sheet insulation net 13 is arranged on the position of the corresponding rotating sheet 5 of insulating barrier main body 11, for isolating rotating sheet 5, make in the assembling process of battery, lug in battery and rotating sheet 5 are isolated, avoid being susceptible to because battery is short-circuited explosion danger, improve the effect of safety.
Preferably, rotating sheet insulation net 13 is constituted network structure by some dowels, adopts some dowels to constitute cancellated form, it is possible to play the effect saving material.Due to the dowel adopting network structure to use, every dowel is all relatively thin, in assembling process or in battery use procedure, is easier phenomenon fracture occur.Therefore, it can at least one in some dowels is reinforcement so that reinforcement can strengthen other dowel, thus playing the effect of the intensity of reinforced insulation layer 1, it is achieved that the effect that can also guarantee safety while economizing on resources.
Additionally, due to the built-in a large amount of chemical substances of battery, such as electrolyte, charge and discharge process can produce mixing gas and liquid etc. in a large number, incident also have the pressure constantly gathered, therefore blast for preventing the easy pressure of cell contents excessive, generally on battery internal head cover sheet 2, be provided with explosion-proof valve 3.Charge and discharge process can produce mix in gas and liquid in a large number, also occur some Mars, for stopping Mars ejection, correlation technique adopt welding metal rack below coping plate 2 realize stopping.Due to, metal rack gravity is relatively big, and needs in welding process to expend the regular hour, therefore in the present embodiment, the metal rack in correlation technique replaces with screen cloth 14, and screen cloth 14 is arranged on the position of insulating barrier main body explosion-proof valve 3, is used for stopping Mars.Achieve reduce battery cap overall weight at the same time it can also be simplify assembling complexity, shorten installation time, solve cost.
Preferably, the upper surface at screen cloth 14 place is provided with groove, the bottom area of groove is identical with the area of screen cloth 14, the groove arranged is while stopping Mars, the volume by screen cloth 14 of the gas in battery can also be increased, make gas after by screen cloth 14, before reaching the explosion-proof valve 3 of coping plate 2, it is possible to have certain volume to converge.Achieve and increase the gas effect by screen cloth 14 volume.
Wherein, screen cloth 14 can be made up of the hole of the various shapes such as waist-shaped hole, tri-angle-holed, circular port, square opening, namely, there is multiple passage, multiple passages can arrange according to certain rule, forms gas passage, it is preferred to use multiple waist-shaped holes form, such as, adopt multiple long 1mm, mode that the waist-shaped hole of wide 0.5mm is evenly distributed forms screen cloth 14.Preferably, in screen cloth 14, the aperture area summation in each hole accounts for the 30%～80% of explosion-proof valve 3 area.At the same time it can also be arrange breach in the side corresponding with screen cloth 14 position of insulating barrier 1 main body, it is also possible to form gas passage.The effect arranging screen cloth 14 is in that when battery generation thermal runaway, both can guarantee that ventilation effect, it is possible to prevent again high temperature immobilized particles by screen cloth 14, thus preventing flammable other to be ejected into outside explosion-proof valve 3 together with high-temperature solid granule and air mixing ignition, thus significantly improving battery safety.
Insulation net in battery in the present embodiment, after installing battery, namely after the assembling of battery entirety, at the liquid injection hole 4 of battery cap sheet 2 to fluid injection in battery.Therefore, insulating barrier 1 is provided with liquid through-hole 15, and liquid through-hole 15 is arranged on the position of insulating barrier 1 main body correspondence liquid injection hole 4.Make the liquid by liquid injection hole 4, it is possible to enter in battery by liquid through-hole 15 smoothly, it is achieved that accelerate the effect of production procedure.
It should be noted that the battery inner insulating layer 1 in the present embodiment, owing to there will be the situation that temperature is too high in battery use procedure, therefore, insulating barrier 1 is made for high-temperature insulation material.Such as, phenolic resin and composite, polyimides and composite thereof are used, politef and composite thereof, polyformaldehyde and composite thereof, polyether-ether-ketone and composite thereof, Muscovitum and composite etc. thereof, specifically used material, it is possible to be adjusted according to battery use occasion.
Preferably, described screen cloth 13 is made for metal material, described battery inner insulating layer other parts except screen cloth 13 are that high-temperature insulation material is made, screen cloth 13 and battery inner insulating layer other parts except screen cloth adopt the one-time formed mode of injection moulding to make so that the screen cloth 13 of metal material becomes as a whole with other parts.
The battery inner insulating layer 1 of the present embodiment, by being arranged below insulating barrier 1 at battery internal head cover sheet 2, wherein the insulating barrier main body 11 in insulating barrier 1 is strip plate profile structure, the two ends of insulating barrier main body 11 arrange hole 12, two pole location, the position corresponding with the rotating sheet 5 on coping plate 2, it is provided with the rotating sheet insulation net 13 for isolating rotating sheet 5, insulating barrier 1 is additionally provided with the screen cloth 14 corresponding with explosion-proof valve 3 position, solve and electrokinetic cell adopts the mode individually assembling each insulating part, the assembling process caused is complicated, the problem of installation time length, achieve in electrokinetic cell, each insulating part needing individually assembling is integrated into insulating barrier 1, while simplifying assembly technology, installation time can also be shortened, reduce production cost.
