Detailed description of the invention
(embodiment)
Below, for the shaping packaging material as embodiments of the present invention, on one side with reference to accompanying drawing explanation on one side.
Fig. 1 is cutting as the shaping packaging material 10 rolling direction D1 of an example of shaping of the present invention packaging materialFace figure.
Be shaped and in showing, possess the shaping lamination of resin bed 2,3, Al-Fe line aluminium alloy paper tinsel 1 with packaging material 10Paper tinsel.
Al-Fe line aluminium alloy paper tinsel 1 is made up of Al-Fe line aluminium alloy.
As this alloy, for example can enumerate Fe content: 0.7～1.3 % by weight, Si content: 0.05～0.3 % by weight, Cu containsAmount: 0.05 % by weight is following, Zn content: below 0.10 % by weight, its surplus is the alloy of Al and other inevitable impurity. SeparatelyOutward, above-mentioned alloy also can contain the Mg of the content below 0.05 % by weight.
In Al-Fe line aluminium alloy paper tinsel, by Fe content is set as to 0.7～1.3 % by weight, with the aluminium foil that does not contain FeCompare, can improve ductility, prevent the generation of the pin hole being caused by bending etc. Because the feelings at Fe content lower than 0.7 % by weightUnder condition, confirm, less than the effect that pin hole produces that prevents in Al-Fe line aluminium alloy paper tinsel, also to confirm the improvement effect less than formabilityReally. In addition, because in the situation that Fe content exceedes 1.3 % by weight, the flexibility of Al-Fe line aluminium alloy paper tinsel 1 suffers damage, rightManufacture in laminated body is not preferred.
In addition, Fe has the effect that makes crystal grain fine, but the effect of adding during lower than 0.7 % by weight is insufficient, if add superCross 1.3 % by weight and produce thick intermetallic compound, not only formability variation, corrosion resistance is variation also.
Si and Fe have the effect that makes size of microcrystal fine jointly, but the effect of adding during lower than 0.05 % by weight is insufficient, asFruit interpolation exceedes 0.3 % by weight, the corrosion resistance variation of paper tinsel.
The thick Z of paper tinsel on the thickness direction D2 of Al-Fe line aluminium alloy paper tinsel 1 is 30 μ m ~ 120 μ m, more preferably 30 μ m ~ 100 μ m,More preferably 30 μ m ~ 40 μ m. The reason that is set as so thick Z of paper tinsel is in order to ensure machinability and prevents invading of moistureThe barrier entering.
If the thickness of Al-Fe line aluminium alloy paper tinsel 1, lower than 30 μ m,, when compressing (deep drawing shaping), easily drawsPlay the fracture of Al-Fe line aluminium alloy paper tinsel 1, even if also easily produce in addition the danger that therefore moisture is invaded such as pin hole in the time not rupturingProperty uprises. On the other hand, if the thickness of Al-Fe line aluminium alloy paper tinsel 1 exceedes 120 μ m, the fracture while can't see for shapingThe further effect of improving, prevent pin hole produce effect also there is no improvement. In addition, only thicken packaging material totalThickness, reduces the weight energy density of the battery that adopts shaping packaging material 10 and volume energy density.
Be 30 μ m ~ 120 μ m with respect to the thickness of Al-Fe line aluminium alloy paper tinsel 1, contained crystalline substance in Al-Fe line aluminium alloy paper tinsel 1The average crystal grain particle diameter of grain is 5 μ m ~ 20 μ m.
Average crystal grain particle diameter is confirmed the further raising less than formability lower than the Al-Fe line aluminium alloy paper tinsel 1 of 5 μ m. In addition,If average crystal grain particle diameter is greater than 20 μ m, become that easily to contain the maximum length L2 shown in Fig. 1 be 0.8 times of above crystal grain(the then coarse grain 4 of explanation), formability reduces.
In Al-Fe line aluminium alloy paper tinsel 1, there are multiple coarse grains 4.
In this manual, so-called coarse grain refers on thickness direction D2 to have the paper tinsel of Al-Fe line aluminium alloy paper tinsel 10.6 times of thick Z above and lower than the crystal grain of the maximum length L2 of 0.8 times.
In the situation of 0.6 times of maximum length L2 on the thickness direction D2 of coarse grain 4 lower than the thick Z of paper tinsel, to formabilityMake a very bad impression. In addition, if the maximum length L2 on the thickness direction D2 of coarse grain 4 is the more than 0.8 times of the thick Z of paper tinsel,Near this coarse grain 4, more easily produce pin hole.
In addition, as shown in Figure 1, the distance X of sowing discord of the center C of coarse grain 4 is important apart from 1mm above. If thick4 of large crystal grain to sow discord distance shorter than 1mm, in the time of the shaping being shaped with packaging material 10, easily at Al-Fe line aluminium alloy paper tinselIn 1, produce pin hole.
Resin bed 2,3, preferably one is heat stable resin, another one is adhesion resin, or both are heat-resisting treeFat.
,, as the formation of the packaging material of resin bed 2,3 and Al-Fe line aluminium alloy paper tinsel 1, can enumerate for example heat stable resinI/Al-Fe line aluminium alloy paper tinsel/heat stable resin II/adhesion resin, heat stable resin I/heat stable resin II/Al-Fe line aluminium alloy paper tinsel/Heat stable resin III/adhesion resin, heat stable resin/Al-Fe line aluminium alloy paper tinsel/adhesion resin, heat stable resin I/heat stable resinII/Al-Fe line aluminium alloy paper tinsel/adhesion resin etc.
Being shaped with in packaging material 10, need to prevent the constriction of the Al-Fe line aluminium alloy paper tinsel 1 when compressing(necking) caused fracture, carries out the shaping of sharp-pointed shape. Therefore, as the heat-resisting tree of intensity and percentage elongation excellenceFat, preferably stretched film is at one side or the two sides contact laminating of Al-Fe line aluminium alloy paper tinsel 1. In addition, be shaped and use packaging material 10 to existAfter shaping, seal, therefore can use well and there is stable on heating stretched film.
As stretched film, can use polyamide (nylon) or polyester film. Especially, is preferably rich in heat resistance, intensityThe stretched film high with percentage elongation, directionality is few.
Like this, by the direct layer of one side or two sides at Al-Fe line aluminium alloy paper tinsel 1 by PA membrane or polyester filmPress, or make polyester film and PA membrane stacked, at one side or the two sides contact laminating of Al-Fe line aluminium alloy paper tinsel 1, Ke YiyouImitate the constriction of the Al-Fe line aluminium alloy paper tinsel 1 while suppressing to be shaped, obtain the battery exterior body of dark and sharp-pointed shape.
Use above-mentioned stretched film in the one of resin bed 2,3 or both, preferably by the thickness of stretched filmBe made as 9～50 μ m. If the thickness of stretched film is lower than 9 μ m, while carrying out sharp-pointed shaping, the percentage elongation deficiency of stretched film,In Al-Fe line aluminium alloy paper tinsel 1, there is constriction, the caused cob webbing of fracture of Al-Fe line aluminium alloy paper tinsel 1 easily occurs. SeparatelyOn the one hand, if the thickness of stretched film exceedes 50 μ m, although the intensity of shape maintains improves, prevent Al-Fe line aluminium alloyThe effect of the formability of the fracture of paper tinsel 1, sharp-pointed shape does not improve, in only thickening shaping packaging material 10,Weight energy density and volume energy density are reduced.
Stretched film when contact laminating, is preferably used to biliquid curing type urethanes on Al-Fe line aluminium alloy paper tinsel 1It is dry lamination binding agent. Its reason is that (deep drawing is shaped or the protruding one-tenth of drum owing to can utilizing cold forming after aging (ageing)Shape) fully sharp-pointed shaping of realization.
In addition, use adhesion resin in the one of resin bed 2,3, preferably use poly-as adhesion resinEthene, polypropylene, polypropylene EVA, maleic acid modified polypropene, ethylene-acrylate EVA or ionomer resin etc.Unstretching film. Unstretching film as described above, can improve for invading because of moisture the lithium secondary battery that produces hydrofluoric acidThe chemical-resistant of electrolyte etc., there is good heat sealability, can maintain the sealing of housing, container, therefore preferred. Poly-Propylene, polypropylene EVA (with a small amount of ethene and/or the EVA of other polymerizable monomer), maleic acid modification poly-thirdAlkene, its fusing point be poly equal and more than, sealing intensity is at high temperature high, therefore in the High temperature storage test of batteryThe possibility that causes the unfavorable conditions such as run-down, expansion, fracture in (safety testing) is little, thereby excellent.
Unstretching film can be directly stacked on Al-Fe line aluminium alloy paper tinsel 1, or also can be at PA membrane or polyester filmUpper stacked. But, at the stacked unstretching film of inner face being shaped with the one side of packaging material 10, owing to thering is heat sealability, guaranteeThe high chemical-resistant of the content to electrolyte etc., therefore preferred.
Laminated polyethylene, polypropylene, polypropylene EVA, maleic acid modified polypropene, ethylene-acrylate EVA,When the unstretching film of ionomer resin, no matter base material is Al-Fe line aluminium alloy paper tinsel 1 or stretched film all can use biliquid curing typeUrethanes is dry lamination binding agent.
But as lithium secondary battery, filling and pack and contain electrolyte, because moisture is invaded and is produced hydrogenIn the situation of the such content of fluoric acid, general urethanes is dry lamination binding agent, and this adhesive layer is due to electricitySeparate liquid, acid impact and swelling, exist caking property decline problem. Therefore, preferably use and have fully for organic solvent, acidThe biliquid curing type dry lamination binding agent of close-burning sour modified polypropene system.
Use above-mentioned unstretching film in the one of resin bed 2,3, preferably the thickness of unstretching film is made as to 9～100 μ m. If unstretching film is lower than 9 μ m, thickness after forming is thin, easily produces pin hole, has anti-corrosion for electrolyte etc.The anxiety of property decline. On the other hand, even if use the unstretching film of the thickness that exceedes 100 μ m, chemical-resistant and heat sealability do not have yetThere is further raising, only make volume energy density reduce.
Moreover, the object for raising with the wetability of binding resin, and/or prevent for the moisture due to electrolyteThe dissolving of the Al-Fe line aluminium alloy paper tinsel 1 of the electrolytical decomposition that intrusion causes and the hydrofluoric acid that produces, improves corrosion proof order, preferably Al-Fe line aluminium alloy paper tinsel 1 is implemented the chemical conversion processing of chromium phosphate hydrochlorate processing etc., and/or acrylic acid series is setThe base treatment of the crosslinked painting type of slaine for fat, acrylic acid series water-soluble resin.
In addition, when at least one side to Al-Fe line aluminium alloy paper tinsel 1 has been implemented in the situation of chemical conversion processing, in this changeLearn on conversion processing face, the tack coat that can form across the dry lamination binding agent that is by modified polypropene, or by modificationThe tack coat that polypropylene and polyacrylic coextrusion resin bed form, stacked heat adhesiveness resin bed. Thus, be shaped at deep drawingIn situation for sharp-pointed shape, the pin hole in the angle part of formed products is difficult to produce, and can obtain the good bag of formabilityPackage material.
Base material is in the situation of Al-Fe line aluminium alloy paper tinsel 1, can adopt coetrusion, sandwich laminating by unstretching filmCarry out lamination. In this situation, make, under the mode of Al-Fe line aluminium alloy paper tinsel 1 side bonding modified polypropene, to use modified polypropeneWith polyacrylic coextrusion resin bed as tack coat.
According to the kind of electrolyte, the heat lamination packaging material that use these to be obtained by coetrusion, sandwich laminatingTime, do not need coating, the drying process of binding agent, therefore there is bonding defect few, the reduction of the cohesive force that electrolyte brings is also few,Can obtain the situation of good sealing.
Then, the manufacture method for the shaping the present invention relates to packaging material, lifts concrete example and describes.
