Abstract
The invention discloses an eccentric lithium battery cover comprising a circular substrate, a liquid injection hole arranged thereon and an electrode plate riveted on the circular substrate. The eccentric lithium battery cover is characterized in that the electrode plate and the circular substrate are arranged in an eccentric manner, thereby leading the electrode plate with the opposite electrode to be also welded on the circular substrate of the battery cover. The eccentric lithium battery cover can greatly lower the difficulty of welding processing, reduce the processing procedures and improve the finished product ratio and the production efficiency of the product.
Description
Technical field
The present invention relates to a kind of lithium battery cap, the eccentric lithium battery cap that is provided with of especially a kind of electrode slice.
Background technology
Fig. 1 is the structural representation that traditional lithium battery the two poles of the earth are provided with, as shown in Figure 1: lithium battery cap comprise circular substrate 1, liquid injection hole 2 provided thereon, and thereon electrode slice 3 of riveted joint ', wherein electrode slice 3 ' with described circular substrate 1 be concentric be provided with, and with circular substrate 1 on electrode slice 3 ' have opposite electrode electrode slice 4 ' be welded in lithium battery case 5 inner bottom part 5 '.Promptly because factors such as the restriction of position and safety, can only be welded on both positive and negative polarity on the circular substrate 1 of lithium battery cap respectively and the inner bottom part 5 of lithium battery case 5 ' on, this mode needs two procedures and two machines to weld at least, and the inner bottom part 5 of lithium battery case ' on electrode slice welding have certain degree of difficulty, qualification rate is not high.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of eccentric lithium battery cover that can simultaneously the positive and negative electrode sheet be welded on it.
The present invention is achieved through the following technical solutions:
A kind of eccentric lithium battery cover comprises circular substrate, liquid injection hole provided thereon and is riveted on electrode slice on the circular substrate, it is characterized in that described electrode slice and circular substrate are eccentric to be provided with.
Described electrode slice is positive electrical pole piece or negative electricity pole piece, and the electrode slice that has opposite electrode with it is welded on the circular substrate of battery cover equally, and two electrode slices are separated by a distance.
The invention has the beneficial effects as follows: be provided with because the substrate of electrode slice of the present invention and battery cover is eccentric, be that the positive and negative electrode sheet can be connected on the circular substrate of lithium battery cap simultaneously, therefore greatly reduced the difficulty of welding processing, reduce the operation of processing, improved the rate of finished products and the production efficiency of product.
Description of drawings
Fig. 1 is the structural representation that traditional lithium battery the two poles of the earth are provided with;
Fig. 2 is the structural representation of eccentric lithium battery cover of the present invention.
Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
Fig. 2 is the structural representation of eccentric lithium battery cover of the present invention.
As shown in Figure 2: eccentric lithium battery cover, comprise circular substrate 1, liquid injection hole 2 (being used to inject the electrolyte of lithium battery) provided thereon and be riveted on electrode slice 3 on the circular substrate, electrode slice 3 and circular substrate 1 eccentric the setting, above-mentioned electrode slice 3 is positive electrical pole piece or negative electricity pole piece.
In addition, because electrode slice 3 is provided with circular substrate 1 off-centre of lithium battery cap, then the electrode slice 4 that has an opposite electrode with described electrode slice 3 can be welded on the circular substrate 1 of battery cover equally, make that welding sequence is simplified, the welding processing difficulty reduces, improved the rate of finished products of operating efficiency and product.And electrode slice 3 is separated by a distance with electrode slice 4, each other not influence.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
