Technical field
The present invention relates to a kind of large capacity single body battery.
Background technology
Lithium battery has the specific capacity height, and specific power is big, has extended cycle life, and free of contamination advantage has obtained increasing application again.To mobile phone, toy for children arrives portable power tool greatly from little, electric bicycle, and battery-operated motor cycle has application until electric automobile.
But this battery uses organic electrolyte, and its conductive capability is far below the aqueous solution.In order to improve the ability of its electric current output, the pole plate area of design is very big, thickness as thin as a wafer, the carrying capacity of active matter is extremely low.The battery pole plates area that capacity is little is just very big, is difficult to make, and battery manufacture difficulty capacious is just bigger.And electrode area is more big, the more easy manufacturing deficiency and unbalanced of bringing into.The probability that it quality problems and safety problem self occur just is higher than small-capacity cells from far away.
General factory is all based on the production small-capacity cells, because the application of small-capacity cells is more extensive.So the production technology of small-capacity cells is more smart better, consistency is higher, and mass defect is lower.
Large capacity single body battery volume is big, and the electric current that passes through is big, and the heat of generation is many, but its heat-sinking capability is more much lower than small-capacity cells.So its temperature rise will be higher than baby battery far away.The life-span of high temperature meeting severe impairment battery.
Below as can be known, there is following shortcoming in large capacity single body battery:
1, large capacity single body battery is brought more manufacturing defect aborning easily into, and the probability that goes wrong in the use is big.
2, the production technology of large capacity single body battery is superior not as baby battery, and consistency of product is poor.
3, large capacity single body battery heat-sinking capability is poor, and battery temperature rises higher.
4, the large capacity single body energy content of battery is big, just in case safety problem occurred, its destructive power is big, and is dangerous big, wayward.
Summary of the invention
The object of the present invention is to provide that a kind of reliability height, failure rate are low, the large capacity single body battery of good heat dissipation effect.
For reaching goal of the invention the technical solution used in the present invention be:
A kind of large capacity single body battery, it is characterized in that: comprise the cylindrical cell of a plurality of low capacities, the like pole of the cylindrical cell of a plurality of described low capacities passes through metal connecting sheet respectively, and be unified into large capacity single body battery, the positive and negative end of described large capacity single body battery is fixed by plastic clamp, be equipped with fin between the cylindrical cell row of the adjacent low capacity of described large capacity single body battery, described fin is made up of first fin and second fin, be equipped with the arc section that is coated on the cylindrical cell surface of shell of each low capacity that is in contact with it on described first fin and second fin, the outer end of described first fin and second fin all is connected on the heating panel in the outside.
Further, in the space between described first fin and second fin alignment pin that fin is close to the cylindrical cell surface of shell of low capacity is installed.
Further, the shape and size in the space between the shape of cross section of the big end of described alignment pin and size and first fin and second fin are identical.
Technical conceive of the present invention is with a plurality of better quality with plastic clamp, the performance more two ends up and down of the cylindrical cell of low capacity of homogeneous is fixed, with brace like pole is connected in parallel and forms large capacity single body battery, the capacity of large capacity single body battery equals the cylindrical cell capacity of each low capacity in parallel sum, and its voltage is equivalent to a battery.Can with several large capacity single body battery series connection, form the battery pack of target voltage according to the requirement of output voltage.Between the cylindrical cell row of the adjacent low capacity of large capacity single body battery, fin is installed, coated by the shell of the arc section on the fin with the cylindrical cell of each low capacity, increase the contact area of fin and the cylindrical cell of low capacity, reached better heat radiating effect.And the outer end of fin all be connected to the outside heating panel on, the heat of large capacity single body battery can by each fin conductive to the heating panel of periphery.Fin is better must to be contacted with the housing of the cylindrical cell of low capacity in order to make, can in the space between first fin and second fin, alignment pin be installed, with the surface of shell extruding of fin to the cylindrical cell of low capacity, reach better radiating effect.Described fin can be that metal fin also can be non-metal fin.
Beneficial effect of the present invention:
1, with the cylindrical cell of low capacity and be unified into large capacity single body battery, because the quality height of the cylindrical cell of low capacity descends the failure rate of large capacity single body battery greatly.
2, indivedual cylindrical cells of low capacity go wrong in the large capacity single body battery, generally do not affect other batteries, also can be easy to change, and the reliability of whole large capacity single body battery has improved.
3, the mass defect of the cylindrical cell of low capacity is few, is not easy to occur security incident.Even there is a battery out of joint, its destructive power is little, is not easy to spread to other batteries, handles easily.The fail safe of large capacity single body battery improves greatly like this.
4, be provided with fin between the cylindrical cell row of adjacent low capacity, the arc section of fin is coated on the surface of shell of the cylindrical cell of low capacity, increased the contact area of itself and the cylindrical cell of low capacity, heat transmits easily, heat passes to heating panel, it has entered surrounding space, and heat radiation can make the temperature of large capacity single body battery obviously descend easily.
5, used fin after, reduced the working temperature of large capacity single body battery, can prolong the useful life of battery effectively.
