Abstract

The invention relates to a buckle battery positive plate, which comprises a positive plate, wherein one or two end surfaces of positive plate are arranged with conductive protrusion; when contacting the positive frame, the positive plate and the positive frame will form point contact, to improve the contact property, and confirm better contact between them, with the consumption of material, to confirm the discharge property of battery.

Description

Lithium manganese button primary cell positive plate
Technical field
The invention belongs to button cell, be specifically related to the positive plate in the button cell.
Background technology
Two end faces of the positive plate of button cell all are flat at present.It contacts with anode cover by end face in battery, i.e. face contact.This contact structures directly influence the discharge performance of battery: in the battery use, along with the consumption of material, the contact of positive plate and anode cover is variation gradually, reduces the discharge performance of battery, makes that the discharge capability in the battery can not get fully playing.
Summary of the invention
The object of the present invention is to provide a kind of discharge performance that improves, have the button cell positive plate of a contact, overcoming above-mentioned defective.
Technical scheme of the present invention is: button cell positive plate, it comprises positive plate, is provided with the conductive stud starting point on one or two end face surface of positive plate.
On the end face surface of button cell positive plate, establish the conductive stud starting point, when contacting with anode cover, positive plate forms point with anode cover and contacts, the conductive stud starting point can be born certain pressure, it has not only improved the contact performance of positive plate and anode cover, guarantee simultaneously in the battery use, consumption along with material, keep excellent contact between positive plate and the anode cover, thereby guarantee the discharge performance of battery, promptly under the situation of other parts that do not change battery, can prolong the discharge time of battery greatly.

Embodiment
Button cell positive plate of the present invention is applicable to the positive plate of various button cells and contacting of anode cover; One or two end face surface of positive plate is provided with the conductive stud starting point, and single conductive stud starting point can be located at the center of positive plate and/or positive plate; A plurality of conductive stud starting points evenly are located on positive plate and/or the positive plate currect collecting net.The conductive stud starting point can be positive plate and currect collecting net overall convex starting point.Present embodiment is that example is illustrated with the li-Mn button cell:
As shown in Figure 1, the positive plate of li-Mn button cell is a manganese dioxide 1, and an end face of positive plate 1 adheres to currect collecting net 2, and conductive stud starting point 3 is located on the currect collecting net 2.Conductive stud starting point 3 can be two interconnective parts with currect collecting net 2, also can be a part, and promptly conductive stud starting point 3 is parts of currect collecting net 2, promptly directly processes raised points on currect collecting net 2.The quantity of conductive stud starting point 3 at least one.Having established four conductive stud starting points in the present embodiment evenly is located on the currect collecting net 2, as shown in Figure 2.The conductive stud starting point also can be the overall convex starting point of manganese dioxide 1 and currect collecting net 2.
Other parts at battery do not have under the condition of variation, through above-mentioned improved button cell with without detecting the discharge time of above-mentioned improved button cell:
The battery of nominal 3V carries out discharge examination such as following table at 1.5 kilo-ohms permanent resistance:
Figure C200610109079D00041
Above-mentioned detection is learnt: be the average discharge time of the battery after the improvement: 116.3 hours, be 92 hours the battery average discharge time before improving; Obviously very good through above-mentioned improved effect.
