Abstract
The invention discloses a vacuum press mounting structure of a sodium-sulfur battery. The vacuum press mounting structure comprises a positive electrode shell and a bottom seal cover, wherein the positive electrode shell comprises a cylinder and a convex ring which extends outwards from the lower end of the cylinder; the upper end surface of the bottom seal cover is provided with an annular groove which is adaptive to the convex ring of the positive electrode shell; an outer circular surface of the convex ring is in basic-shaft-system interference fit with an outer groove wall of the annular groove; and the convex ring of the positive electrode shell is pressed into the annular groove of the bottom seal cover through a press. Due to the adoption of the vacuum press mounting structure, the high vacuum degree of a positive electrode of the sodium-sulfur battery can be guaranteed, a condition can be created for final laser welding and sealing in an atmospheric environment, and stable welding quality can be guaranteed.
Description
Technical field
The present invention relates to a kind of Vacuum Pressure assembling structure of sodium-sulphur battery.
Background technology
Sodium sulphur (NaS) battery is the rechargeable battery that a kind of negative pole forms with ceramic alumina class material with sulphur, electrolyte with sodium, positive pole.It has that energy storage density is large, efficient is high, operating cost is low, safeguard be easier to, the advantage such as free from environmental pollution, long service life.
The anodal container of the critical component of sodium-sulphur battery is to be made of anodal shell and sealed bottom lid, and therefore the encapsulation of anodal shell and sealed bottom lid is the key that guarantees anodal seal of vessel.Being fixedly connected with of existing anodal shell and sealed bottom lid is to adopt seam location, edge, then by special fixture, makes both seam two sides stressed, then passes through laser welding sealing.Due to the vacuum state that will guarantee anodal container, therefore anodal shell carries out in vacuum tank with being fixedly connected with all of sealed bottom lid.Because the overall volume of sodium-sulphur battery is larger, one or many batteries comprise positioning fixture, laser welding system, need a larger confined space could satisfy the needs of sodium-sulphur battery high vacuum packaging technology.The problem of bringing is: at first, because the confined space volume is larger, the time that vacuumizes the vacuum degree that reaches required is just long, and the cargo handling process of battery is also more loaded down with trivial details, such technique has produced the production time and the production cost problem that are difficult to overcome in the ever-increasing situation of amount of batteries output; Secondly, the high structural strength to vacuum tank of vacuum degree requires also higher, and the cost of vacuum tank also is doubled and redoubled; In addition, be positioned at the phenomenon that the carbon felt of anodal container bottom often has carbon fiber to come off, vacuumize the junction that often has the carbon fiber extraction to rest on sealed bottom lid and anodal shell, this carbon fiber ability higher temperature (1000 degrees centigrade), high temperature during laser welding can not melt yet, so the carbon fiber filament of sealed bottom lid and anodal shell seam crossing often causes the vacuum state in anodal container to descend.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of Vacuum Pressure assembling structure of sodium-sulphur battery is provided, it can guarantee that the anodal container of sodium-sulphur battery is in higher vacuum degree, create conditions for carry out last laser welding sealing in atmospheric environment, and can guarantee stable welding quality.
The technical scheme that realizes above-mentioned purpose is: a kind of Vacuum Pressure assembling structure of sodium-sulphur battery, comprise the sealing of anodal shell and sealed bottom lid, wherein,
Described anodal shell comprises that cylinder reaches by the outward extending bulge loop in the lower end of cylinder;
An annular groove adaptive with the bulge loop of described anodal shell offered in the upper surface of described sealed bottom lid;
Be the basic shaft system interference fit between the periphery of described bulge loop and the external groove sidevall of described annular groove;
By press, the bulge loop of described anodal shell is pressed in the annular groove of described sealed bottom lid.
The Vacuum Pressure assembling structure of above-mentioned sodium-sulphur battery, wherein, the bulge loop of described anodal shell is pressed in the annular groove of described sealed bottom lid and carries out under vacuum state.
The Vacuum Pressure assembling structure of above-mentioned sodium-sulphur battery, wherein, the annular groove degree of depth that described sealed bottom covers is greater than the height of the bulge loop on described anodal shell.
The Vacuum Pressure assembling structure of sodium-sulphur battery of the present invention, on the one hand when press-fiting, the carbon fiber filament is cut off and is siphoned away by negative pressure by the faying face of the interference fit between sealed bottom lid and anodal shell, for follow-up laser welding sealing creates conditions, welding quality is significantly improved, make anodal container can keep permanent sealing state.On the other hand after press-fiting, making anodal container can be in negative pressure reaches from packing state, follow-up laser welding sealing just can be in atmosphere routinely technique carry out, can dwindle the volume of confined space and therefore reduce the time that vacuumizes, and then efficient is improved and cost.
Description of drawings
Fig. 1 is the schematic diagram of the Vacuum Pressure assembling structure of sodium-sulphur battery of the present invention.
Embodiment
In order to understand technical scheme of the present invention better, also be elaborated by reference to the accompanying drawings below by specific embodiment:
See also Fig. 1, the Vacuum Pressure assembling structure of sodium-sulphur battery of the present invention comprises anodal shell 1 and sealed bottom lid sealing 2, wherein,
An annular groove 20 adaptive with the bulge loop 12 of anodal shell 1 offered in the upper surface of sealed bottom lid 2;
Be the basic shaft system interference fit between the diameter D of the external groove sidevall of the diameter of the periphery of bulge loop 12 and annular groove 20;
Under vacuum state, by press, the bulge loop 12 of anodal shell 1 is pressed in the annular groove 20 of sealed bottom lid 2.
Due to the height of annular groove 20 degree of depth on sealed bottom lid 2 greater than the bulge loop 12 on anodal shell 1, in the time of can guaranteeing to press-fit, the bulge loop 12 of anodal shell 1 enters in the annular groove 20 of sealed bottom lid 2 fully, making anodal shell 1 keep stable with sealed bottom lid 2 is connected, the laser welding operation that easy operating is follow-up can access enough weld strengths.
After adopting the Vacuum Pressure assembling structure of sodium-sulphur battery of the present invention, when the sealed bottom lid press-fits with anodal shell is stressed, the carbon fiber filament is siphoned away by negative pressure after being cut off by the interference fit faying face between sealed bottom lid and anodal shell, for follow-up laser welding sealing creates conditions, therefore welding quality significantly improves and keeps stable, makes anodal container can keep permanent sealing state.。
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
