Abstract
The invention relates to an energy-type lithium thionyl chloride battery, and in particular relates to a method and device for processing a lithium thionyl chloride battery cathode. The method comprises the following steps of: cutting lithium sheets and rolling the cut lithium sheets in a circular shape as well as placing circular cut lithium sheets in a shell; and inserting cylindrical supports with a tensioning force adjustment function into the shell and then stretching the cylindrical supports so that the cut lithium sheets are compressed and closely adhered to the inner wall of the shell. The cylindrical supports which are arranged around a tapered cylinder in the circumferential direction are combined together, thus being smaller in diameter and stretching outwards under the pushing action of the tapered cylinder, thus the lithium sheets are compressed and closely adhered to the inner wall of the shell. The lithium sheets manufactured by the invention are relatively rough in surface and larger in discharge reaction area and stronger in activity, and strengthen the discharge performances of products.
Description
Technical field
The present invention relates to a kind of energy type lithium thionyl chloride cell, relate in particular to a kind of processing method and device thereof of lithium thionyl chloride cell negative pole.
Background technology
When the energy type lithium thionyl chloride cell was made, when pressing this manufacturing procedure of lithium sheet, the lithium sheet needed to be close to the stainless steel box hat inwall of battery.Like Fig. 1, shown in Figure 2; Present traditional processing method is to adopt the method for double-roller roll-in, along under initiative roll shaft 5 active force radially, lets lithium sheet 2 and box hat 1 be clamped between two rollers at driven roll shaft 6; Initiative roll shaft 5 rotates under the drive of motor; Because function of friction, lithium sheet 2, box hat 1, driven roll shaft 6 threes rotate together, and the lithium sheet is being close under the effect of two roller roll-ins on box hat 1 inwall.
Adopt the method for this pressure lithium sheet, can make initiative roll shaft form cantilever beam, produce certain deflection deformation, make the suffered active force of lithium sheet and initiative roll shaft contact-making surface inconsistent, and cause rolling up lithium, promptly soft lithium sheet is bonded on the initiative roll shaft; Downforce also can cause soft lithium sheet distortion, and when the lithium sheet rolled along with initiative roll shaft, the surface can form the waveform irregular lines; Lithium sheet surface is polished cunning in the roll-in process in addition, reduces lithium sheet surface contact area greatly, and the reaction speed of negative pole is reduced.This technical method can cause the volume lithium, makes the lithium sheet scrap, be prone to make this procedure to do over again, and has influence on the discharge performance of product, causes the wasting phenomenon of material, labor hour etc., has increased manufacturing cost to company.
Summary of the invention
One of the object of the invention is in order to overcome above-mentioned deficiency of the prior art, to provide a kind of and can lower owing to the lithium sheet pinning phenomenon that discontinuity causes, the processing method of increasing work efficiency, reduce the lithium thionyl chloride cell negative pole of manufacturing cost.
Two of the object of the invention is in order to overcome above-mentioned deficiency of the prior art, to provide a kind of and can lower owing to the lithium sheet pinning phenomenon that discontinuity causes, the processing unit (plant) of increasing work efficiency, reduce the lithium thionyl chloride cell negative pole of manufacturing cost.
For realizing above goal of the invention; Technical scheme of the present invention is: a kind of processing method of lithium thionyl chloride cell negative pole; Its difference is: earlier circular with being rolled into after the cutting of lithium sheet; Put into housing, insert column type strutting piece then, strut the column type strutting piece and make the extruding of lithium sheet be close on the inner walls with the power of tightening adjustment.
A kind of processing unit (plant) of lithium thionyl chloride cell negative pole; Comprise column type strutting piece with the power of tightening adjustment; Thereby cutting some parts, the vertical grade of the excircle of column type strutting piece makes that its diameter is adjustable; The column type strutting piece has central taper hole, is provided with in the central taper hole to adjust mobile tapered cylinder up and down.
Preferably, said column type strutting piece is provided with it is fastened on the elastic component on the conical column body cone.
The invention has the beneficial effects as follows: it is less to combine its diameter around the column type strutting piece of tapered cylinder circumferential arrangement, under the suppressing action of tapered cylinder, outwards opens, and makes the extruding of lithium sheet be close on the inner walls.
Through the pattern that struts of this no roll-in of the present invention, add and can not cause local pressure roller man-hour, there is not rolling slip factor yet, at utmost keep the shape on lithium sheet surface, the vertical placement, the lithium sheet can not produce displacement; Lithium sheet non-displacement barrier film can not occur and break, and carbon electrode distortion etc. are unusual, electric liquid can not occur and gather and react incomplete situation in local richness; The lithium sheet is opposed flattened also, and the exoelectrical reaction meeting is more abundant, local situation about reacting completely earlier can not occur, has guaranteed the consistency of product capacity; Lithium sheet surface is coarse relatively, and the exoelectrical reaction area is bigger, and activity is stronger, has increased the discharge property of product.

Embodiment
Further specify the specific embodiment of the invention below in conjunction with accompanying drawing.
Like Fig. 3, shown in Figure 4; A kind of processing method of lithium thionyl chloride cell negative pole, earlier circular with being rolled into after 2 cuttings of lithium sheet, put into housing 1; Insert column type strutting piece 3 then, strut column type strutting piece 3 and make 2 extruding of lithium sheet be close on housing 1 inwall with the power of tightening adjustment.
Referring to Fig. 3, Fig. 4, Fig. 5; A kind of processing unit (plant) of lithium thionyl chloride cell negative pole; Comprise column type strutting piece 3 with the power of tightening adjustment; Make that its diameter is adjustable thereby the vertical grade of the excircle of column type strutting piece 3 is cut some parts, column type strutting piece 3 has central taper hole, is provided with in the central taper hole to adjust mobile tapered cylinder 4 up and down.
Preferably, can on column type strutting piece 3 peripheries, cannelure be set, in said cannelure, be provided with column type strutting piece 3 is fastened on the elastic component (elastic component can adopt spring or other device, does not draw these parts among the figure) on the conical column body cone 4.
Concrete, above-mentioned column type strutting piece 3 excircles vertically wait and cut 3-5 part, install in the middle taper hole and can adjust mobile tapered cylinder 4 up and down, because the tangent plane spillage of material makes the diameter of column type strutting piece 3 diminish after combining; Under the effect that receives tapered cylinder 4, outwards open, column type strutting piece 3 returns to the size of original diameter, thereby the extruding of lithium sheet is close on the battery steel shell inwall.
Earlier the lithium sheet is cut into rectangle, is rolled into circularly, put into box hat, insert the processing unit (plant) of lithium thionyl chloride cell negative pole, this device can make the extruding of lithium sheet be close on the box hat inwall.
Above content is to combine concrete execution mode to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
