Abstract
A lithium battery anode cover group relates to the field of lithium batteries and comprises an anode cover and an anode pole, wherein a carving slot is arranged on the upper surface of the anode cover, and the anode pole is hermetically connected with the center of the anode cover through a glass insulator; and the lithium battery anode cover group is characterized in that a plurality of discharge holes are arranged on the anode cover and are filled with pieces of sealed glass. In the lithium battery anode cover group, a discharge system is formed by the glass-sealed discharge holes and the glass insulator, thus being capable of effectively protecting the safety of the lithium batteries under extreme conditions of short circuit and high temperature, and the like. When heat control loss causes increasing of internal pressure, the pressure is acted on the axial anode cover group of the lithium battery, the sealed glass in the discharge holes breaks and deforms under the stress action, and the pressure is discharged firstly from the discharge holes, thus achieving an anti-explosion effect.
Description
Technical field
The utility model relates to lithium battery, refers to a kind of lithium battery anode lid group particularly.
Background technology
As the lithium in the primary cell system-thionyl chloride primary cell system, specific energy is the highest in all at present known chemical power sources, and have voltage height, big, the advantages such as the serviceability temperature scope is wide, discharge performance is steady, storage life is long, Maintenance free of power, therefore obtained extensive use.But this disposable lithium-battery is when representing its superiority, and its shortcoming also progressively displays, i.e. fail safe is relatively poor, and especially under the situation that battery is abused, burning, blast happen occasionally, and have caused a large amount of personal injurys and property loss.
The utility model content
Technical problem to be solved in the utility model just provides a kind of lithium battery anode lid group, can improve the security performance of lithium battery by release pressure.
For solving the problems of the technologies described above, a kind of lithium battery anode lid group that the utility model provides, comprise positive cover and positive terminal, the upper surface of described positive cover is provided with to carve hinders groove, described positive terminal is connected with the positive cover central seal by glass insulator, its special feature is: described positive cover is provided with some escape orifices, is filled with seal glass in the escape orifice.
In the technique scheme, described escape orifice is arranged to carve hinders in the groove, and evenly distributes along circumference.
In the technique scheme, described escape orifice is three to six.
The beneficial effects of the utility model are: form bleed-off system with the escape orifice of glass capsulation with the glass insulator at positive terminal place, can effectively guarantee the safety of lithium battery under extreme conditions such as short circuit, high temperature.When voltage rise was high in thermal runaway causes, pressure acted on the axial positive cover group of lithium battery, the seal glass failure by rupture of escape orifice under stress, and pressure at first leaks from escape orifice, has reached explosion-proof effect.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1-positive cover, 2-carve and hinder groove, 3-positive terminal, 4-glass insulator, 5-escape orifice.
Embodiment
Below in conjunction with accompanying drawing a specific embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of lithium battery anode lid group of the present utility model comprises positive cover 1 and positive terminal 3, the upper surface of positive cover 1 is provided with to carve hinders groove 2, hindering in the groove 2 machinings quarter has 5, four escape orifices of four escape orifices 5 evenly to distribute along circumference, uses glass capsulation in it.3 of positive terminals pass through glass insulator 4 and are connected with positive cover 1 central seal.Like this, four escape orifices 5 constitute bleed-off system with glass insulator 4, can be under extreme conditions such as lithium battery short circuit, high temperature release pressure, guarantee the person and property safety.
Core of the present utility model is by the harm of escape orifice 5 to avoid disposable lithium-battery to cause because of improper use is set on the positive cover 1 of disposable lithium-battery, so its protection range is not limited to the foregoing description.Obviously, those skilled in the art can carry out various changes and distortion to the utility model and not break away from scope and spirit of the present utility model, and for example: the position of escape orifice and number can be provided with according to the specification of disposable lithium-battery.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and is out of shape interior.
