Further, pass through Welding between described ceramic ring and pole and cover plate.Soldering can weld dissimilar metal, also can weld foreign material, and to thickness of workpiece difference without strict restriction, is thus applicable to ceramic ring and welding between pole, cover plate.In addition, the thermal endurance of soldering is not high, when battery runs into high-temperature condition, weld is by high temperature, and the sealing now between pole and cover plate will be destroyed, therefore disappointing function can be played, it should be noted that, it is all generally because there is uncontrollable reaction that battery destroys, and produces a large amount of heats and gas in the short time, if can not release heat and gas in good time, battery will be blasted.Therefore this programme can allow battery automatically open function of losing heart when producing high temperature, thus pressure release, avoid battery explosion.
Further, the solder that uses of the soldering mixing that is a kind of in Sn, Ag, Cu, Mg, Al, Si, Ni or at least two kinds.When welding aluminum or aluminum alloy and pottery, welding temperature is 300 ~ 660 DEG C, welds in atmosphere or welds in vacuum, N2, nitrogen and hydrogen mixture; When soldering copper or copper alloy and pottery, welding temperature is 300 ~ 1083 DEG C, in atmosphere welding or weld in vacuum, N2, nitrogen and hydrogen mixture.By experiment, above-mentioned soldering scheme can allow the weld of battery can by high temperature between 250 ~ 400 DEG C, and be more conducive to the explosion prevention function of battery, fail safe is better.
Further, the material of described ceramic ring is the mixing of a kind of in aluminium oxide, zirconia, silica, silicon nitride or aluminium nitride or at least two kinds.
Further, described ceramic ring is that toroidal or the band toroidal of boss or I-shaped are circular.Circular annular form with boss or the circular contact area can guaranteed with pole and cover plate of I-shaped, make sealing more firm and reliable, sealing property is better.
Further, the material of described pole and cover plate is the one in copper, copper alloy, aluminium, aluminium alloy, and the surface of described pole and cover plate is provided with electrodeposited coating, and the material of electrodeposited coating is the compound of a kind of in gold, silver, copper, chromium, tin, nickel or at least two kinds.
Compared with prior art, the beneficial effects of the utility model are:
Owing to being sealed by ceramic ring between pole and cover plate, thus there is good high temperature resistant, high strength, high rigidity, good electrical property, hot property and chemical stability.Adopt the mode of refractory ceramics insulated enclosure to extend the useful life of sealing, also extend the useful life of battery simultaneously.In addition, by welding mode, can allow ceramic ring firmly with pole and cover plate compact siro spinning technology.In addition, being welded by the mode of soldering, battery can being allowed automatically to open function of losing heart when producing high temperature, thus pressure release, avoid battery explosion.
