Abstract
The utility model discloses an anti-deformation cathode cover plate. The diameter of the cathode cover plate is greater than 40 mm; a liquid injection hole is formed in the cathode cover plate; the liquid injection hole is 5 to 10 mm away from the cathode cover plate. According to the anti-deformation cathode cover plate, the deformation of the cathode cover plate caused by the colliding and the pressing when liquid is injected for sealing can be avoided effectively; the processing of a primary lithium battery is facilitated; the usability of the primary lithium battery is guaranteed.
Description
Technical field
The utility model belongs to disposable lithium-battery technical field, is specifically related to a kind of negative pole cover plate that prevents deformation.
Background technology
As the lithium-thionyl chloride primary cell system in primary cell system, in at present known all chemical power sources, specific energy is the highest, have advantages of that voltage is high, power large, serviceability temperature scope is wide, discharge performance is steady, storage life is long, Maintenance free, in the market battery requirements is not content with to conventional size, but occur that volume is large, the battery that capacity is high, must cause the individuality of battery associated materials to increase like this.The general design of the liquid injection hole of disposable lithium-battery negative pole cover plate is at present in the center of whole circular cover, but, because negative pole cover plate is along with battery size does larger and larger, size also increases thereupon, and liquid injection hole is arranged on cover plate center, after fluid injection bruising, because surface area is excessive, easily make the generation deformation of caving in of negative pole cover plate.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of negative pole cover plate that prevents deformation, and the deformation that bruising anticathode cover plate when it can effectively avoid fluid injection sealing causes is conducive to disposable lithium-battery processing, has ensured the usability of disposable lithium-battery.
The utility model solves the technical scheme that its technical problem adopts: prevent the negative pole cover plate of deformation, the diameter of described negative pole cover plate is greater than 40mm, and described negative pole cover plate is provided with liquid injection hole, and described liquid injection hole is apart from the edge 5～10mm of negative pole cover plate.
By technique scheme, described liquid injection hole is apart from the edge 8mm of negative pole cover plate.
The utility model, there is following beneficial effect: the liquid injection hole of cancelling negative pole cover plate center, but at the edge of negative pole cover plate processing liquid injection hole, carry out in the process of fluid injection sealing at negative pole cover plate end like this, can effectively prevent that bruising when the excessive negative pole cover plate center of surface area seals because of fluid injection from making negative pole coverplate stress generation deformation, be conducive to disposable lithium-battery processing, ensured the usability of disposable lithium-battery.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment.
Wherein, 1-negative pole cover plate, 2-liquid injection hole.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In preferred embodiment of the present utility model, as shown in Figure 1, prevent the negative pole cover plate of deformation, the diameter of this negative pole cover plate 1 is greater than 40mm, is provided with liquid injection hole 2 on negative pole cover plate 1, and liquid injection hole 2 is apart from the edge 5～10mm of negative pole cover plate 1, in general, liquid injection hole is apart from the edge 8mm of negative pole cover plate.The utility model only need be cancelled the existing liquid injection hole that is positioned at negative pole cover plate center in the time of machining, and at the edge of battery cathode cover plate processing liquid injection hole.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection range of the utility model claims.
Claims (2)
