Abstract
The utility model discloses a cylindrical lithium-ion battery, which comprises a battery body; whereon, anode and cathode terminals are arranged on the battery body. The battery body is a hollow structural body with an annular cross-section. The hollow shape inside the battery body can be cylindrical, elliptic cylindrical or prismatic. The battery body is provided with at least one pair of anode and cathode terminals which can be arranged at one end or both ends of the battery body. The lithium-ion battery with such a structure enables the battery to timely dissipate heat accumulated inside the battery in the running process, so that the battery can be used in a safer way. The existing lithium-ion battery structure is a solid structure which goes against heat dissipation, while the hollow-structured battery protected by the utility model is more conducive to heat dissipation. The lithium-ion battery with such a structure can keep working in an appropriate temperature environment, reduce the requirements on battery consistency and improve the cycle life of batteries and battery packs.
Description
Technical field
The utility model relates to a kind of column lithium ion battery.
Background technology
Along with the shortage day by day of global fossil energy, oil price constantly surging, and the problem of environmental pollution that increasingly sharpens, people are more and more urgent to the demand of clean reproducible energy.Lithium ion battery has been widely used in communication, electron trade as a kind of efficient renewable energy source carrier, particularly on person-to-person communication such as mobile phone, the PDA instrument.Nearly one or two years, develop rapidly along with mechanics of communication, mobile phone color screen technology, multimedia message technology, Bluetooth technology and camera technique are continuous mutually to be occurred, and the indexs such as capacity, volume, weight, chemical property and fail safe of lithium ion battery are had higher requirement.
For requiring big capacity, powerful field, such as applications such as electric motor car, UPS, communication apparatus, the fail safe of lithium ion battery is particularly important.The key factor that influences lithium ion battery security is that the heat that battery produces down in working order can't in time be got rid of, but accumulation gradually, last thermal runaway produces accident on fire from explosion, brings harm and loss to the client.Present lithium ion battery structure is solid construction, is unfavorable for the eliminating of heat.
Usually the operating voltage of single lithium ion battery has only about 2.4～4.5V, and the capacity of single battery is also very limited, and all processes of at present big capacity, powerful electrokinetic cell are carried out outside series/parallel to single battery and formed.Whether the design of single lithium ion battery structure helps heat radiation, and whether the coherence request that satisfies battery pack is arranged, and also is one of emphasis of researching and developing of insider.
The utility model content
Technical problem to be solved in the utility model provides a kind of good heat dissipation, column lithium ion battery that security performance is high.
For solving the problems of the technologies described above, this column lithium ion battery comprises battery body, and battery body is provided with the positive and negative electrode binding post, and described battery body is the hollow-core construction body of ring-shaped section and ring-shaped.
Battery body boring shape can be cylindrical or elliptical cylinder-shape or for prismatic in the such scheme.Positive and negative electrode binding post on the battery body has at least a pair of.The positive and negative electrode binding post can be arranged on battery body one end, also can be located at the two ends of battery body respectively.
The lithium ion battery of said structure helps battery and in the course of the work the heat of inside savings is in time shed, and it is safer that battery is used.Existing lithium ion battery structure is solid construction; be unfavorable for the eliminating of heat; and the hollow-core construction battery of the utility model protection; help heat radiation more; for the environment for use of a large amount of heat radiations of needs, can also artificially add refrigeration radiating devices such as ventilation fan, cooling water simultaneously at the lithium ion battery center.Lithium ion battery with this structure can remain on suitable temperature environment work, can reduce the coherence request to battery, improves the cycle life of battery and battery pack.
Description of drawings
Fig. 1 is the structural representation of utility model column lithium ion battery;
Fig. 2 is another structural representation of utility model column lithium ion battery.
Embodiment
The invention will be further described by embodiment below in conjunction with accompanying drawing.
Column lithium ion battery as shown in Figure 1, it comprises battery body 1, and the positive terminal 2 and the negative terminal 3 of drawing from battery body 1.Battery body 1 is the hollow-core construction body, and its profile is a cylindrical shape, and the cross section is structure in the form of a ring, and battery body boring shape is cylindrical.Positive terminal 2 of drawing from battery body and negative terminal 3 are at the same end of battery body 1.Another execution mode of the present utility model as shown in Figure 2, the positive terminal 2 of column lithium ion battery ' and negative terminal 3 ' then lay respectively at battery body 1 ' two ends.In addition, battery body boring shape also can be an elliptical cylinder-shape or prismatic, and it is how right that each battery positive and negative electrode binding post also can be designed as, and the pore size of battery body boring can be determined according to the heat degree of distributing.
Winding method is mainly adopted in the utility model manufacturing, and the lithium ion battery of solid construction is the axle center with the volume pin normally, will roll up heart extraction rubberizing behind the coiling, packs into then in packaging film or the liquid steel aluminum hull, encapsulates again, fluid injection, operation such as changes into.And can carry out around hollow shaft during this structure battery winding, roll up afterwards hollow shaft not extract out, the shell of directly packing into as interior ring, becomes the part of battery case, encapsulates then to get final product.The benefit of such winding-structure is to avoid the probability of conventional coiling battery part, helps improving the rate of finished products of battery.
The lithium ion battery of this structure can also be formed big capacity, powerful electrokinetic cell by serial or parallel connection, the heat that produces because of electrokinetic cell work is bigger, can add heat abstractor at the battery center, such as, ventilation fan, cooling water etc., so more effectively heat radiation improves the fail safe of using battery.This structure lithium ion battery can reduce the coherence request to battery, improves the cycle life of battery and battery pack.
