Description
Affiliated technical field
The present invention relates to a kind of battery, refer to the overpower circular batteries particularly.
Background technology
The structure of the present circular sealed cell of secondary (capacity type or power-type batteries such as NI-G, ni-mh, lithium ion): the shell of battery is as negative pole, and the block of battery is as positive pole, and the electric core of battery is made up of positive plate, negative plate and diaphragm paper.
But current delivery channel design pattern traditional design has following defective between the both positive and negative polarity of electric core and battery:
1. the electric core cathode output end of battery and as the existing two kinds of schemes of type of attachment between the block inboard of anode:
1. with two ends of strip sheet metal (industry slang claims " lug ") respectively with electric core positive terminal and the block inboard company of weldering mutually;
2. the anodal end face of electric core earlier with " sheet metal " welding, two ends of using " lug " again are respectively with " sheet metal " and " block " company of weldering mutually;
Which kind of scheme no matter, the electric core positive terminal of conventional batteries design all adopts " lug " this connector to make transmission channel to current channel structure between blocking a shot.
The present situation that " lug " is applied to the circular sealed cell of secondary is: material is conductance not high " nickel strap " (nickel strap resistivity: 7.14 * 10-8/m) or " nickel plated steel strip " (steel band resistivity: 10～20 * 10-8/m); According to the battery size difference, the general about 0.10～0.25mm of lug thickness, the about 2.0～8.0mm of width, length is about 12.0～30.0mm; Its cross-sectional area is if all get maximum estimation, the cross-sectional area Smax=2mm of monolithic lug
2
According to the International Power association criterion: it is 4A/mm that bare copper wire allows current density
2(the resistivity of copper: 1.69 * 10-8/m); Can calculate that from resistivity it only is 0.95A/mm that wall scroll " bare electrode ear " allows current density
2Even many lugs are also made conductive carrier, it is impossible will allowing it pass through tens～one, 200 A (ampere) electric current during battery overpower operating conditions, the result of Shi Yonging is by force: according to Ohm's law, produce very big voltage drop and " power consumption " on the lug, power consumption is inevitable to be discharged with " heat energy " form--the important source of rapid temperature rise during-battery super-large current work that Here it is; So the current delivery channel design beyond the electric core positive terminal of the power-type battery of traditional design is super-large current work " bottleneck ".
2. be connected the existing three kinds of schemes of traditional design between the electric core cathode output end of battery and the shell inboard:
1. the negative plate outermost layer of electric core directly contacts with the shell of battery is inboard, claims " contact ";
2. use " lug " to make transmission conductor: two ends of lug are connected with electric core cathode output end and the inboard spot welding of outer casing bottom respectively;
3. the negative pole end face of electric core earlier with narrow meshed unidirectional sheet metal (being that little hole flanging is unidirectional) welding, treat that electric core packs into behind the housing, with " point " weldering (generally welding three, five points) mode " unidirectional sheet metal " welded with the shell inboard;
Obviously:
The 1. 2. the kind scheme make the current delivery body according to lazy " contact " or " lug ", it is infeasible using on the overpower type battery of big electric current;
3. the scheme defective workmanship be: the big current delivery passage of the cathode output end of electric core is by the little hole flanging on " unidirectional sheet metal ", and the very little solder joint of the several cross-sectional areas of piggybacking is transferred to (as the negative pole of battery) shell again;
As seen, the current delivery channel design of the electric core negative pole end outside of the power-type circular batteries of traditional design is " bottleneck " of super-large current work equally.
Development along with electrical equipment industry, fields such as oily, electric hybrid vehicle, electric power Transport Machinery, weapons vehicle, the aircraft electric power energy, emergency electric power power supply all need battery that high power or overpower operating state are provided, even the electric core of battery has the overpower ability, if there is not outstanding transmission current passage, the conductive channel in the battery can't be finished overpower type transformation task at all.
