Description
Technical field
The utility model belongs to the battery technology field, is specifically related to a kind of combination power battery.
Background technology
Along with the development of World Economics, the international petroleum price fluctuateed acutely in recent years, and the expection of following petroleum resources reduces in addition, and oil has become the bottleneck of development of world economy, and therefore, new forms of energy become the new direction of developing the economy.Along with the shortage day by day of global fossil energy, 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 source carrier of renewable energy efficiently, 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 security performance of lithium ion battery are had higher requirement.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.
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.At present big capacity, powerful electrokinetic cell are all formed through single battery is carried out outside series connection/parallel connection.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.Lithium ion battery structure is solid construction at present, is unfavorable for the eliminating of heat.Therefore, 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.
In the prior art, electrokinetic cell all is that there is the common drawback that security performance is low, the impulse electricity cycle-index is few, serviceability differs from three aspects in this two classes battery with square solid the most common with the circular solids battery.Specific as follows:
Rectangular cell inside is combined by some pole pieces, and battery is inner ion high-speed motion when work, and internal temperature raises.Because of rectangular cell overall structure defective, inner heat can't outwards be discharged, thereby cause the battery case distortion, inner pole piece distortion, spacing variable effect battery charge, discharge quality finally cause battery performance instability, explosive, life-span weak point.
The circular solids inside battery is solid by pole piece coiling and combines, and battery inner ion when work runs up, and internal temperature raises.Overall structure because of the circular solids battery, the inside battery heat can't outwards be discharged, influence battery charge, discharge quality thereby cause inside battery pole piece spacing not wait, internal heat can't discharge simultaneously, finally causes battery performance instability, explosive, life-span weak point.
At present, the electrokinetic cell that development capacity is big, the life-span is long, security performance is good has become the common recognition of national governments, conglomerate, estimate that 21 century will become one of major impetus power supply of electric automobile, and will be used widely aspect artificial satellite, Aero-Space and the energy storage.
Summary of the invention
The purpose of this utility model is to provide a kind of safe, good heat dissipation, long new structure electrokinetic cell of life-span.
The utility model is achieved through the following technical solutions:
Combination power battery includes plural battery unit and is combined into one; Described each battery unit includes: shell, battery body and electrode; Described battery body is arranged in shell, includes the pole piece that is arranged in parallel; Wherein, the outer surface of the shell of described each battery unit is provided with heat abstractor.
To sum up, the beneficial effects of the utility model are:
Combination power battery of the present utility model is to carry out omnibearing improvement design on traditional power battery heat radiation difficulty, explosive, cycle-index defective basis few, that the charging interval is long.Combination power battery of the present utility model because the outer surface of shell is provided with heat abstractor, 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.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.
