Its high reliability, high security.In addition, the system battery also has low stable operating voltage, self discharge, low hysteresis, ring
The features such as border close friend, it is one of most potential Military Power in The Next 3-5 Years.But the low electric conductivity of fluorocarbons in itself influences
Make the high current and low temperature performance of the system battery.To improve the power and cryogenic property of lithium/fluorination carbon battery, mesh
Before the mode taken be adjustment electrolyte prescription or anode formula, such R＆D cycle length, cost is high.
Utility model content
The purpose of this utility model is to provide a kind of disposable lithium-battery anode collection structure, and it can increase catchment area
The power and cryogenic property of battery are improved, also ensures the fixing that anode collection bar is connected with Positive Poles, can effectively subtract
Few battery failure caused by rosin joint, improve the reliability of battery.
Technical scheme is used by the utility model solves its technical problem：
A kind of disposable lithium-battery anode collection structure, including cover plate, Positive Poles and plus plate current-collecting body, the Positive Poles
Be tightly connected with the cover plate central, the bottoms of the Positive Poles is provided with groove, the plus plate current-collecting body including collector bar with
And point is welded in the current collecting plates of the collector bar bottom sides, the top point of the collector bar is welded in the groove.
By above-mentioned technical proposal, the groove depth of the groove is the 1/4~1/3 of Positive Poles length.
By above-mentioned technical proposal, the width of the collector bar is 5~10mm.
By above-mentioned technical proposal, the current collecting plates are shaped as disc or square disc shape.
By above-mentioned technical proposal, connected between the current collecting plates and collector bar by laser spot welding.
By above-mentioned technical proposal, the collector bar is made using aluminium foil.
By above-mentioned technical proposal, connected between the collector bar and Positive Poles by ultrasonic spot welding.
The utility model, have the advantages that：The utility model has carried out light-weight design to Positive Poles, uses
Short pole, be groove structure by its bottom design, not only increase the area of collector spot welding, and add collector with just
The fixing of pole pole, the battery failure caused by rosin joint can be effectively reduced, improve the reliability of battery；Meanwhile positive pole
Collector is integrally attached to using collector bar and current collecting plates, can be significantly increased catchment area, be efficiently solved disposable lithium-battery and put
The problem of electric multiplying power is low, cryogenic effect is bad.
