Description
Technical field
This utility model belongs to cell art, is specifically related to a kind of lithium thionyl chloride battery cover
Group structure.
Background technology
Lithium thionyl chloride cell (Li/SOCl2) it is a kind of with lithium as anode, carbon makees cathode carrier, nothing
Thionyl chloride (the SOCl of water tetrachloro-lithium aluminate2) solution makees the lithium battery of electrolyte, it has ratio
Energy is high, specific power big, wide, length storage life of discharging voltage balance, temperature applicable range etc.
Characteristic.The lid group of lithium thionyl chloride cell in the design process, needs reserved enough air chambers
Carry out the pressure within buffer battery.At present, lithium thionyl chloride battery cover group structure as it is shown in figure 1,
It increases and improves the method in inside battery space is to be additionally arranged at the bottom of ring-type felt pad at cover plate 4
Block 10, by the space between cross-over block 10 outer wall and battery case 1 inwall as air chamber.
This lid group structure, when cross-over block design is relatively thin, does not reaches the purpose improving inner space；
When insulation spacer design is thicker, owing to battery case height is fixed, it is necessary for reducing the thickness of cover plate
Degree, this can reduce the intensity of lid group, and then reduce the service life of lithium thionyl chloride cell.
Summary of the invention
The purpose of this utility model is contemplated to solve the deficiency that above-mentioned background technology exists, it is provided that
A kind of lithium thionyl chloride battery cover group structure.
The technical solution adopted in the utility model is: a kind of lithium thionyl chloride battery cover group structure,
Including battery case and positive/negative lead wire lever, described battery case inner upper end is sequentially provided with from outside to inside
Fluid sealant, cover plate and insulation spacer, described positive/negative lead wire lever one end is positioned at outside battery case,
The positive/negative lead wire lever other end sequentially passes through the middle position of described fluid sealant, cover plate and insulation spacer
Inside battery case, the positive/negative lead wire lever surface within described cover plate is cased with glass envelope, described
Cover plate convexes to form boss near a middle side part of insulation spacer.
Further, the side of described cover plate gluing, sealing glue is provided with groove, and described fluid sealant is filled out
Fill in groove, the undercut slots that described recess sidewall lower end concave shaped circularizes.
Further, the inwall section of described undercut slots is fold-line-shaped.
Further, the cross section of described boss is circular or polygon.
This utility model is on the premise of guarantee glass envelope and battery case height are constant, by lid
The bottom of plate arranges boss, compared to existing technology, eliminates a cross-over block, is ensureing lid
While plate intensity, improve inside battery space, simple in construction, reasonable in design.
Groove lower end outside this blind flange arranges the undercut slots of annular, when fluid sealant encapsulates
Glue enters in undercut slots, and after solidification, sealing property will be greatly improved.

Detailed description of the invention
With specific embodiment, this utility model is made the most below in conjunction with the accompanying drawings
Bright, it is simple to be well understood to this utility model, but they do not constitute restriction to this utility model.
As in figure 2 it is shown, this utility model lithium thionyl chloride battery cover group structure includes battery case 1
With positive/negative lead wire lever 2, described battery case 1 inner upper end is sequentially provided with fluid sealant from outside to inside
3, cover plate 4 and insulation spacer 5, described positive/negative lead wire lever 2 one end is positioned at outside battery case 1
Portion, positive/negative lead wire lever 2 other end sequentially passes through described fluid sealant 3, cover plate 4 and felt pad
It is internal that the middle part of sheet 5 is positioned at battery case 1, positive/negative lead wire lever 2 table within described cover plate 4
Surface cover has glass envelope 6, and described cover plate 4 convexes to form convex near a middle side part of insulation spacer 5
Platform 7, glass envelope 6 flushes with boss 7 bottom surface, and the medial surface of such cover plate 4 is the formation of platform
Terrace, after battery installs, insulation spacer 5 is fitted boss 7, boss 7 sidewall and battery
Space between shell 1 inwall is used for buffering interior pressure as air chamber 11.The cross section of boss 7
Can be circular or polygon, such as square, pentagon.
This utility model is on the premise of guarantee battery case 1 and glass envelope 6 are the most constant, at lid
The bottom of plate 4 arranges boss 7 by the method for punching press, compared to existing technology, eliminates one
Cross-over block, is ensureing while cover plate intensity, improves inside battery space, simple in construction,
Reasonable in design.
As it is shown on figure 3, cover plate 4 is provided with groove 8, described sealing in the side of gluing, sealing glue
Glue is filled out 3 and is filled in groove 8, and general groove 8 sidewall is upright inclined-plane, this utility model groove
The undercut slots 9 that the sidewall 8.1 lower end concave shaped of 8 circularizes, i.e. the side wall lower ends at groove 8 is dug
Go out an annular breach as undercut slots 9.Inwall 9.1 section of undercut slots 9 can be arbitrary shape
Shape, preferably fold-line-shaped, in when fluid sealant 3 encapsulates, glue enters undercut slots 9, after solidification
Sealing property will be greatly improved.
The content not being described in detail in this specification belongs to known to professional and technical personnel in the field
Prior art.
