Abstract
The utility model relates to a button cell negative plate, which is provided with a lithium block punched by a lithium strip. The button cell negative plate has low cost and good contact property.
Description
Technical field
The utility model relates to the technical field of button cell, and especially a kind of cost is low, the button cell cathode sheet that contact is good.
Background technology
The Production and Packaging technology of the negative plate of traditional button cell is will connect the inner bottom surface that the site is welded in the negative pole metal shell earlier, then the lithium sheet is pressed together on and connects on the net, connect general being welded on the negative pole metal shell inner bottom surface of can extremely not fitting of net, also will cause and the lithium sheet that is connected the net pressing metal shell inner bottom surface of can extremely not fitting, and then cause the contact of entire cell bad; Simultaneously, a large amount of uses connects net, and cost is higher relatively, and connects the active ingredient that net has also occupied inside battery, allows effective release property of negative pole weaken.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem in the above-mentioned background technology, the utility model provides a kind of cost low, the button cell cathode sheet that contact is good.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of button cell cathode sheet has the lithium piece by the punching press of lithium band.
Further, the lithium band is square long band.
Further, the lithium piece is circular.
The beneficial effects of the utility model: cancelled the connection net in the button cell cathode sheet of the present utility model, make cost reduce widely, production process is simplified simultaneously, efficient is improved, enlarged the useful space of inside battery, effective release property of negative pole has improved 10%, and the contact of lithium piece and negative pole metal shell inner bottom surface is better.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of existing button cell cathode sheet;
Fig. 2 is the structural representation of the utility model omissive representation.
Among the figure 1, the lithium sheet, 2, connect net, 3, the lithium band, 4, the lithium piece.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of button cell cathode sheet as shown in Figure 2, have the lithium piece 4 by 3 punching presses of lithium band, wherein lithium band 3 is square long band, and lithium band 3 is formed by connecting by some square blocks, lithium piece 4 is obtained by stamping machine punching press square block, and the lithium piece is the circular configuration that is complementary with negative pole metal shell inner bottom surface.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (3)
