Description
Technical field
The utility model relates to technical field of lithium batteries, especially a kind of button lithium battery.
Background technology
Button lithium battery is a kind of novel chemical power source, and as the main fresh combatants of chemical power source, its market prospects are very extensive, can do electrical source of power and memory power supply.As electrical source of power, the application of lithium battery in medical product, telecontrol engineering gets more and more; As memory power supply, be widely used in the fields such as computer main board.
It is little that button lithium battery has volume, and cell voltage is high, and discharging voltage balance, the features such as operating temperature range is wide, and storage life is long, are widely used in computer main board, calculator, electronic watch, remote controller, electronic toy and ornaments etc.
The fastening lithium ionic cell of current use mostly is circular, for microscler Intelligent worn device, can not meet it and use, and is therefore badly in need of a kind of lithium ion battery that can meet this kind of wearable device and use.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model proposes the special-shaped lithium battery of a kind of button, its objective is that providing a kind of solves the problem that existing circular button cell can not be applicable to Wearable etc.
In order to solve above-mentioned technical problem, the basic technical scheme that the utility model proposes is: the special-shaped lithium battery of a kind of button, comprising:
Negative cover and positive cover, this negative cover and positive cover fasten formation containing cavity, in described containing cavity, be sequentially metal lithium sheet, barrier film and positive plate by negative cover side to positive cover side;
Described negative cover and positive cover are flange lid, and this negative cover and positive cover elongated, the both sides semicircular in shape of negative cover and positive cover, its interlude is rectangle.
Further, in the junction of described negative cover and positive cover, there is sealing ring.
Further, the thickness of described negative cover and positive cover is 0.25mm.
Further, the inner surface of negative cover and metal lithium sheet are provided with negative current collector.
Further, described negative current collector is a wire netting, and its shape is identical with the inner surface of negative cover.
The beneficial effects of the utility model are:
What the special-shaped lithium battery of a kind of button of this practicality adopted is elongated shell mechanism, namely the two ends of shell are circular, interlude is square, this technology can be suitable for installing and using of the long and narrow space of the equipment such as Intelligent bracelet, solves the problem that button cell is in the past unsuitable for the use of intelligent belt-type apparatus.Meanwhile, the technical solution of the utility model can be used for large-scale machines and produces, and can greatly increase work efficiency.In addition, technology highly versatile of the present utility model, for electronic product provides suitable power supply.
Accompanying drawing explanation
Fig. 1 is the appearance schematic diagram of the special-shaped lithium battery of a kind of button described in the utility model;
Fig. 2 is the cutaway view of the special-shaped lithium battery of a kind of button described in Fig. 1;
Fig. 3 is the vertical view of negative cover.
Embodiment
Be described further below with reference to accompanying drawing 1 to accompanying drawing 3 pairs of the utility model, but protection range of the present utility model should do not limited with this.
Contrast accompanying drawing 1 to accompanying drawing 3:
The special-shaped lithium battery of a kind of button of the utility model, comprises negative cover 10 and positive cover 20, and this negative cover 10 and positive cover 20 fasten the shell forming lithium battery.The described elongated shape of negative cover 10, concrete comprising is positioned at first 101 of two ends and be positioned at second 102 of interlude, first described 101 semicircular in shape, described second 102 is rectangle structure, and the length of this negative cover 10 and the ratio of width are greater than 2, can be 3,4 or 5 etc.In addition, this negative cover 10 is flange lid, and its flange extends internally.In the utility model, described positive cover 20 is identical with the structure of negative cover 10, does not therefore repeat.
Negative current collector 30, metal lithium sheet 40, barrier film 50 and positive plate 60 is respectively arranged with by negative cover 10 side to positive cover 20 side in the containing cavity 01 that negative cover 10 and positive cover 20 are formed.Wherein, the joint portion of negative cover 10 and positive cover 20 is provided with a sealing ring 70.
Concrete, negative current collector 30 of the present utility model is wire netting, and the inner surface of its compact siro spinning technology metal lithium sheet 40 and negative cover 10, contributes to transmission current like this.
In addition, the thickness of negative cover 10 of the present utility model and positive cover 20 is the very thin thickness of 0.25mm, use, can improve the containing cavity space of this lithium battery, to improve charge capacity.
The utility model due to adopt negative cover 10 and positive cover 20 be slender structure, therefore for belt electronic product, especially wearable device and use, meet the demand of a lot of electronic product.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
