Abstract
The utility model discloses an eccentric lithium battery cover which comprises a round substrate, a liquid-injecting hole arranged on the round substrate and an electrode sheet riveted on the round substrate. The eccentric lithium battery cover is characterized in that the electrode sheet and the round substrate are arranged eccentrically to each other, so that an electrode sheet with the opposite pole to the electrode sheet can also be welded on the round substrate of the battery cover. The eccentric lithium battery cover greatly reduces the difficulty in welding and processing, reduces the processing procedure and increases the finished product rate and the production efficiency.
Description
Technical field
The utility model 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.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of eccentric lithium battery cover that can simultaneously the positive and negative electrode sheet be welded on it.
The utility model 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 beneficial effects of the utility model are: be provided with because the substrate of electrode slice described in the utility model 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 described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail:
Fig. 2 is the structural representation of eccentric lithium battery cover described in the utility model.
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 utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection range of the present utility model.
