Embodiment
Followingly the NaS battery of the utility model is described with the hot press structure of member and the NaS battery that possesses this structure with reference to accompanying drawing.In addition, hereinafter, the formation identical with the NaS battery (with reference to Fig. 3) of existing example omitted its explanation.As shown in Figure 1, hot press structure 10 is connected structures of dead ring 4, anode metal spare 5 and cathodic metal spare 6.
The flange part (being equivalent to first flange part) 52 that anode metal spare 5 possesses cylindrical portion (being equivalent to first cylindrical portion) 51 and stretches out to internal direction from the lower end of cylindrical portion 51.The flange part (second flange part) 62 that cathodic metal spare 6 possesses cylindrical portion (being equivalent to second cylindrical portion) 61 and stretches out to outside direction from the periphery of cylindrical portion 61.
In addition; For hot press structure 10; Under the state in the cylindrical portion 51 of dead ring 4 being inserted anode metal spare 5; On flange part 52 with dead ring 4 below opposed first area R1 possess the first hot press portion 11, below flange part 62 with above the dead ring 4 opposed second area R2 possess the second hot press portion 12.
In the hot press structure 10 of the utility model, need make the area of the first hot press portion 11 account for first area R1 more than 5% of area, make the area of the second hot press portion 12 account for the accounting for more than 5% of area of second area R2.Through assigned position is carried out hot press with the distance of regulation, just can improve the strength reliability at junction surface of junction surface and the cathodic metal spare 6 and the dead ring 4 of anode metal spare 5 and dead ring 4.Thus, the junction surface can not corroded and the good engagement state of long term maintenance by sodium isoreactivity material easily.In addition; In this embodiment; Thereby further improve the strength reliability at junction surface for the joint distance that increases anode metal spare 5 and dead ring 4 and with the joint distance of cathodic metal spare 6 and dead ring 4; First area R1 integral body is carried out the incompatible formation of the thermo-compressed first hot press portion 11, and second area R2 integral body is carried out the incompatible formation of the thermo-compressed second hot press portion 12.
In addition; For hot press structure 10; In the cylindrical portion 51 of anode metal spare 5, insert under the state of dead ring 4; Possessing the 3rd hot press portion 13 with the inner peripheral surface of cylindrical portion 51 and opposed the 3rd region R 3 of outer peripheral face of dead ring 4, and possessing the 4th hot press portion 14 at the outer peripheral face that is positioned at the cylindrical portion 61 below leaning on than flange part 62 and opposed the 4th region R 4 of inner peripheral surface of dead ring 4.In the NaS battery of existing example; Usually be provided with the gap in the 3rd region R 3 and the 4th region R 4; But like this embodiment; Not only possess the first hot press portion 11 and the second hot press portion 12 and also possess the 3rd hot press portion 13 and the 4th hot press portion 14, can increase the joint distance of anode metal spare 5 and dead ring 4 and the joint distance of cathodic metal spare 6 and dead ring 4 thus, and improve anti-active material corrosivity.
Then, joint method is described.Anode metal spare 5 uses hot press with cathodic metal spare 6 with engaging of dead ring 4.That is, as shown in Figure 2, the cylindrical portion 51 that is arranged at the anode metal spare 5 on the downside joining jig 91 is inserted dead rings 4 and is positioned on the flange part 52, so on dead ring 4 placement cathodic metal spare 6.In addition, be filled with brazing metal among first area R and the 1 second area R2.
Under such state; Exert pressure if be heated to about 500-560 ℃ and through upside joining jig 92; Then as shown in Figure 2; In the flange part 52 of anode metal spare 5, its thickness reduce and when internal direction (among Fig. 2 left to) is extended the part of the brazing metal of first area R1 move to the 3rd region R 3, thereby the first hot press portion 11, the 3rd hot press portion 13 are engaged; In addition; In the flange part 62 of cathodic metal spare 6, its thickness reduce and when outside direction (Fig. 2 right-of-center in political views's direction) extends the part of the brazing metal of second area R2 move to the 4th region R 4, thereby the second hot press portion 12 and the 4th hot press portion 14 are engaged.In addition; For brazing metal; As stated; During hot press the part of the brazing metal of first area R1 and second area R2 move to the 3rd region R 3 and the 4th region R 4 also passable, but before the hot press in advance on the 3rd region R 3 and the 4th region R 4 the configuration brazing metal also be fine.
