Abstract
The utility model is a round lithium ion battery, comprising an upper battery cover, a lower battery cover, an anode pillar of battery, and a cathode pillar of battery, wherein the anode pillar of battery and cathode pillar of battery are respectively arranged on both upper and lower ends of the battery; the anode pillar and cathode pillar are separated from the upper battery cover and lower battery cover. With high safety performance and higher battery performance, the utility model overcomes the design drawbacks in the existing technology and is easy to process.
Description
Technical field
The utility model relates to a kind of lithium ion battery, particularly relates to a kind of lithium ion battery of improved circular configuration.
Background technology
Along with popularizing of portable digital products such as mobile phone, digital camera, MP3, its used lithium ion battery has been proposed better requirement, not only require it that very high energy density is arranged, and want cube littler, performance is higher, and fail safe also ensures again.In the lithium ion battery structure of prior art, ubiquity several problems: the one, and the security performance problem.Because the positive and negative terminals of lithium ion battery is often too close in the prior art, thereby easily causes short circuit, brings potential safety hazard.The 2nd, structure is too complicated, brings the inconvenience in the processing, influences production efficiency.
The utility model content
The purpose of this utility model is to design in order to overcome defective of the prior art, and a kind of security performance height is provided, and is easy to processing, and the lithium ion battery of the also higher novel circular configuration of battery performance.
For realizing the purpose of this utility model.Propose a kind of lithium ion battery of circular configuration, it includes cell cover, the battery lower cover, and the anode post, the battery cathode post, described anode post 2, battery cathode post 3 lay respectively at the two ends up and down of battery container 1.Be not easy short circuit like this, improve the fail safe of battery.
As a kind of improvement, lithium ion battery structure of the present utility model can also be designed to described positive terminal 2, negative terminal 3 is the structures that are separated from each other with cell cover 4, battery lower cover 5.So, fit together with cap again after positive and negative terminals welds respectively prior to positive and negative lug when assembling, help like this operating in the production process, enhance productivity.
As a kind of improvement, lithium ion battery structure of the present utility model can also be designed to: the bottom 9,10 of described positive terminal 2 and negative terminal 3 is a quadrilateral structure.
As a kind of improvement, lithium ion battery structure of the present utility model can also be designed to: soldering polar ear respectively on the bottom 9,10 of the both positive and negative polarity of described lithium ion battery.For the positive and negative terminals of quadrangular base, difference soldering polar ear on four sides of this quadrangular base 9,10.This structure can be applied to multipole ear cylindrical battery.
Adopt the lithium ion battery of the utility model structure, improved battery conductive, reduce battery internal resistance, improve the rate charge-discharge performance, simultaneously easy to process, the security performance height.
Description of drawings
Fig. 1 is the utility model lithium ion battery overall structure schematic diagram.
Wherein
1 housing, 6 explosion-proof valves
2 positive terminals, 7 explosion-proof valves
3 negative terminals, 8 liquid injection holes
4 loam cakes, 9 positive terminals bottom
5 lower covers, 10 negative terminals bottom
Embodiment
Below in conjunction with accompanying drawing the utility model lithium ion battery overall structure is elaborated.As shown in the figure, the lithium ion battery of circular configuration of the present utility model, it includes housing 1, cell cover 4, battery lower cover 5, anode post 2 and battery cathode post 3.If the battery plus-negative plate post all is arranged on the loam cake 4, because distance is too close between the battery plus-negative plate post, then be easy to cause the short circuit of the two, not only there is serious potential safety hazard, and also damage easily of battery.Therefore the technical solution of the utility model adopts anode post 2, battery cathode post 3 is separately positioned on the loam cake 4 and lower cover 5 at battery two ends, is not easy short circuit between the battery plus-negative plate post like this, improves the fail safe of battery.Simultaneously, the positive terminal of battery, negative terminal and cell cover, battery lower cover are connected to each other together in the prior art, and this has caused the inconvenience on the fabrication and processing.The utility model is designed to described positive terminal 2, negative terminal 3 is separated from each other with cell cover 4, battery lower cover 5, so, when assembling, positive and negative terminals fits together with cap respectively with after bottom 10 welding of the bottom 9 of positive terminal 2, negative terminal 3 with positive and negative lug earlier again, help like this operating in the production process, enhance productivity.
The lithium ion battery of circular configuration of the present utility model can also be designed to described positive terminal bottom 9, negative terminal bottom 10 can be designed to quadrilateral structure.Certainly can also be other polygonized structures, adopt polygonized structure after, just can be on a plurality of sides of pole soldering polar ear, as quadrilateral structure, then can both the welding electrode ear in four sides of pole, thereby can be applied to multipole ear cylindrical battery.
The loam cake 4 and the lower cover 5 of lithium ion battery of the present utility model are provided with explosion- proof valve 6 and 7, improve the lithium ion battery overall security.Simultaneously, liquid injection hole 8 is arranged on the loam cake 4, convenient filling electrolyte.
