Description
Technical field
This utility model is related to cell art, specially a kind of button cell.
Background technology
Button cell（button cell ）Also referred to as button cell, refers to overall dimensions as the battery of a little button, one
As for be relatively large in diameter, thinner thickness（Relative to batteries such as No. 5 AA on prismatic battery such as market）, button cell is from profile
On come to battery dividing, equal corresponding cell classification has prismatic battery, rectangular cell, Special-shaped battery.Existing button cell,
Surface easily scratches, and hardness is not high enough, and the size of current of the Resistance Influence electric discharge of inside.It is when button cell is processed, right
The damage of machine also can be very big impact.
Utility model content
The purpose of this utility model is to provide a kind of button cell, to solve the problems, such as to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme：
A kind of button cell, including negative electrode casing and positive cover, block in being provided with mounting groove, and mounting groove inside the negative electrode casing
Negative electrode casing is connected to, the negative electrode casing is connected by mould-injection closing with the edge clamping position of positive cover, the negative electrode casing inner chamber
Upper surface connect lithium piece lower surface, and lithium piece upper surface connect barrier film lower surface, the barrier film upper surface connection
The lower surface of positive plate, and the upper surface of positive plate is connected with the lower surface of positive pole cover cavity.
Preferably, the lithium piece, barrier film and positive plate are column structure.
Preferably, the periphery sides of the barrier film pass through the medial wall closing of mould-injection and negative electrode casing.
Compared with prior art, the beneficial effects of the utility model are：This button cell simple structure, by adopting ferroelectricity
Positive and negative pole material of the nickel plating as lithium manganese button cell, can effectively reduce scratching for battery surface, and the hardness of nickel is than stainless iron
Hardness is high, and nickel has good wearability, is difficult to scratch, conducts electricity very well, and can reduce the resistance of battery, and electric discharge property is more preferably, stainless
Added with carbon in ferrum, carbon is non-conductive, and ferrum during shell is rushed, than the more preferable punching press of stainless steel and iron, can reduce the wear intensity of board, reduce
Board maintenance frequency, reduces production cost.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1-2 is referred to, this utility model provides a kind of technical scheme：
A kind of button cell, including negative electrode casing 1 and positive cover 5, wherein, negative electrode casing 1 and positive cover 5 adopt ferroelectricity nickel plating
As the material of lithium manganese button cell, scratching for battery surface can be effectively reduced, the hardness of nickel is higher than the hardness of stainless iron, and nickel has
Good wearability, is connected with negative electrode casing 1, negative electrode casing 1 and positive cover 5 inside negative electrode casing 1 in being provided with mounting groove, and mounting groove
Edge clamping position connects the lower surface of lithium piece 2, and lithium piece 2 by the closing connection of mould-injection 6, the upper surface of 1 inner chamber of negative electrode casing
Upper surface connect the lower surface of barrier film 3, the upper surface of barrier film 3 connects the lower surface of positive plate 4, and the upper surface of positive plate 4
It is connected with the lower surface of 5 inner chamber of positive cover, conducting electricity very well for battery can reduce the resistance of battery, and electric discharge property is more preferable, lithium piece 2,
Barrier film 3 and positive plate 4 are column structure, and the periphery sides of barrier film 3 pass through the medial wall closing of mould-injection 6 and negative electrode casing 1, can
Effectively to prevent electric leakage.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
Be appreciated that these embodiments can be carried out various changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
