Yet the electrolyte of lithium ion battery has moisture or the more weak characteristic of light.Therefore, the housing material that is used for lithium ion battery the has used lamination substrate layer (resin film) that constitutes by polyamide or polyester and aluminium foil, water proofing property or the outstanding battery external packing of light-proofness use laminate.
When in the accommodating container that uses this battery external packing to make, taking in lithium ion battery, for example use the carrying container 30 shown in Fig. 3 A with laminate.Use the battery external packing to make hypocraterimorphous carrying container 30 through forming methods such as drawing and formings in advance, in the recess 31 of this pallet (carrying container 30), take in lithium ion battery (not shown) and electrode 36 accessories such as (with reference to Fig. 3 B) with recess 31 with laminate.Then, shown in Fig. 3 B, cover in the above by the battery external packing and come packaged battery, the flange part 32 of pallet and the side edge part 34 around the cladding material 33 are sealed, thus sealed cell with the cladding material 33 that laminate constitutes.For the accommodating container of making through this method of carrying battery 35 at the recess 31 of pallet, owing to can take in battery from top, so productivity ratio is high.
In the carrying container 30 of the lithium ion battery shown in above-mentioned Fig. 3 A, the degree of depth of pallet (below, maybe the degree of depth of pallet being called " drawing depth ") was about 5～6mm in small-sized lithium ion battery in the past.Yet in recent years, in the application in the electric automobile etc., requiring provided the large-sized battery bigger than the accommodating container size of present use to use accommodating container.When the manufacturing large-sized battery is used accommodating container, must form pallet with darker drawing depth, this will increase technical difficulty.
And when moisture entered into the inside of lithium ion battery, electrolyte and reaction of moisture caused electrolyte to be decomposed, and produced strong acid (hydrofluoric acid etc.).At this moment, the strong acid that is produced is penetrated into the battery external packing from its inboard and uses laminate, possibly cause aluminium foil by the strong acid corrosion and by deterioration.Its result not only makes electrolyte leak, and battery performance is descended, but also possibly cause lithium ion battery on fire.
As prevent to constitute above-mentioned battery external packing with the superficial layer of the aluminium foil of laminate and electrode cable member by the countermeasure of strong acid corrosion; Disclose in the TOHKEMY 2000-357494 communique through carry out the chromate processing on the surface of aluminium foil and formed chromaking processing film, improved the countermeasure of corrosion resistance thus.But, owing in chromate is handled, use the chromium of heavy metal, therefore consider not to be preferred version from the viewpoint of environmental protection, Cr VI uses chromic chromate treatment fluid at present because be the harmful substance that human body is exerted an influence and can't using.In addition, with regard to the chemical conversion beyond chromate is handled was handled, the effect that improves corrosion resistance was relatively poor.
And; In the existing electrode cable member; Its electrolyte resistance performance of aluminium as the electrode member of positive pole in anodal and these two electrodes of negative pole is higher, and as the copper coin of the electrode member of negative pole, even the nickel plating on the top layer; And then implement chromic chromate and handle, its electrolyte resistance performance is still lower.
Summary of the invention

Embodiment
Referring to figs. 1 through Fig. 6 electrode cable member involved in the present invention is described.And, illustrate from utilize the battery external packing with the lithium ion battery of laminate manufacturing with the electrode cable member of drawing the accommodating container.
As shown in Figure 1, electrode cable member of the present invention 18 and lithium ion battery 17 are encapsulated in battery that folding battery external packing makes with laminate 10 (with reference to Fig. 2) with outer containter 20 the insides.
Battery is that side edge portions 19 to its three directions seals and processes the member of flat pocket-like with outer containter 20.Electrode cable member 18 is the wire elements that form along lamellar (band shape) of predetermined direction extension.Electrode cable member 18 as shown in Figure 1 from battery with drawing the outer containter 20.That is, electrode cable member 18 via battery with in the side edge portions 19 on a limit of outer containter 20 be resealed the position and by being drawn.And, use electrode cable member 18 of the present invention and the battery of the lithium ion battery processed with the accommodation method in the accommodating container, and utilize Fig. 3 A identical with the described method of Fig. 3 B.
, as shown in Figure 2 by the formed battery external packing of laminated film laminate with laminate 10, bonding between substrate layer 11 and the aluminium foil 12 through adhesive phase 15, bonding between aluminium foil 12 and the resin film 13 through adhesive phase 16.That is, the battery external packing is formed by the ironed film of aluminium lamination (aluminum laminated film) with laminate 10.
Shown in Fig. 4 A and Fig. 4 B, electrode cable member 18 has by aluminium sheet to be processed or by the leading-out portion of being processed by the copper coin that nickel coating coated 21.And, on the surface of leading-out portion 21, the thin film coated layer 22 of the corrosion resistance that forms through resin or its copolymer resins by polyvinyl alcohol skeleton with hydroxyl, lamination has sealing material layer 23.
Containing the resin that formed by the metal fluoride or derivatives thereof, make the polyvinyl alcohol skeleton with hydroxyl that is comprised in the thin film coated layer 22 or its copolymer resins in the thin film coated layer 22 takes place crosslinked and makes the material of metal surface activation.But even do not contain the metal fluoride or derivatives thereof in the thin film coated layer, the corrosion resistance of electrode cable member also has raising than in the past.
Thin film coated layer 22 is formed at leading-out portion 21 surfaces through printing with pattern-like.For this pattern, will be described in detail later.
Crosslinked or the decrystallized resistance to water that has takes place through heat treatment in the thin film coated layer 22 that is formed at the surface of leading-out portion 21.
And; The material that ionization is acidity takes place under aqueous solution state through in the thin film coated layer, adding as metal fluoride (or derivatives thereof); Make metal surface (surface of leading-out portion 21) activation, powerful bonding between the film of metal surface and thin film coated layer thus.
In addition, the known common gas barrier property of thin film coated layer that is formed by the resin with polyvinyl alcohol skeleton or its copolymer resins is good.The resin internal voids that forms the thin film coated layer is few, especially under the lower atmosphere of humidity, for also having gas barrier property such as the less gas molecule of hydrogen equimolecular diameter.Therefore, can think and use in the battery of nonaqueous electrolytic solution at lithium battery, capacitor etc., when using the thin film coated layer, higher to the barrier of electrolyte, moisture as the component parts of the inside battery that does not have moisture to exist.Therefore, also high to the barrier of the material of erode metallic surfaces such as hydrofluoric acid, have etch-proof effect thereby can predict.And, for the thin film coated layer that forms by resin selected, that have the polyvinyl alcohol skeleton or its copolymer resins from the material that contains hydroxyl, can the crosslinked corrosion resistance of seeking to improve take place through making it.
In the leading-out portion 21 of electrode cable member 18, general anodal use aluminium sheet, and negative pole uses the copper coin that is coated by nickel coating.For being easy to carry out closing, form sealing material layer 23 in advance in the bonding part of electrode cable member 18 by the hot joining of the ironed film formed battery external packing of aluminium lamination with laminate 10 and electrode cable member 18.Preferably, sealing material layer 23 is laminated to leading-out portion 21 two sides, with sandwich leading-out portion 21 in table.
When the top layer at leading-out portion 21 does not form the thin film coated layer 22 of corrosion resistance, according to the infiltration of electrolyte towards electrode cable member 18, the reaction of moisture and electrolyte may take place and produce hydrofluoric acid on the top layer of leading-out portion 21.And, may cause the bonding deterioration between leading-out portion 21 and the sealing material layer 23 because of the hydrofluoric acid corrosion leading-out portion 21 that produces.Therefore, preferably, the thin film coated layer 22 that forms by resin or its copolymer resins of polyvinyl alcohol skeleton in the top layer face laminated of the part that is inserted into battery of leading-out portion 21 at least with hydroxyl.Shown in Fig. 4 B, with the bonding part of housing material (the battery external packing is with laminate 10) in, need be at the whole periphery laminated thin film coated layer 22 in the cross section of leading-out portion 21.
As the anticorrosion countermeasure to electrolyte of employed aluminum leading-out portion 21 in the electrode cable member that prior art provided, relevant, the chromate that is widely used is handled.Yet, compare with aluminum leading-out portion 21, for the leading-out portion 21 of on copper, implementing nickel plating, the chromate treatment effect is relatively poor.But the inventor confirms that according to the present invention, the leading-out portion 21 on copper, implementing nickel plating also has the anticorrosion ability to electrolyte.
Thus, the inventor thinks that the anticorrosion mechanism to electrolyte according to thin film coated layer 22 of the present invention is different from the chromate processing of prior art.
And the various metallic plates such as copper coin that thin film coated layer 22 can be directed against aluminium sheet, cover nickel coating obtain anticorrosion abilities, therefore preferably on the two leading-out portion 21 of anodal and negative pole, thin film coated layer 22 are set all.
Resin or its copolymer resins with polyvinyl alcohol skeleton of hydroxyl are the resins through vinyl esters polymer of monomers or its copolymer generation saponification are obtained.
As the vinyl esters monomer, can enumerate aromatic vinyl esters such as fatty acid vinyl esters such as formic acid ethene, vinyl acetate, butyric acid ethene or benzoic acid ethene.As other monomer that carries out copolymerization, can enumerate unsaturated acids such as ethene, propylene, alpha-olefines, acrylic acid, methacrylic acid, maleic anhydride, halogen vinyl such as vinyl chloride or vinylidene chloride etc.The G polymer resin (trade name) that Japanese synthetic chemistry Co., Ltd. makes can be enumerated in the commercially available prod.
And, preferably, contain the resin or its copolymer resins that form by the metal fluoride or derivatives thereof, make the polyvinyl alcohol skeleton that is comprised in the thin film coated layer 22 in the thin film coated layer 22 crosslinked material take place with hydroxyl.As the metal fluoride or derivatives thereof, for example can enumerate the fluoride of charomic fluoride, ferric flouride, zirconium fluoride, titanium fluoride, hafnium fluoride, fluorine zirconic acid and their salt, fluotitanic acid and their salt etc.These metal fluoride or derivatives thereofs are to make the resin of the polyvinyl alcohol skeleton with hydroxyl or its copolymer resins that crosslinked material take place, and also are the F that contains the aluminum fluoride that is used to form passive state simultaneously
-The material of ion.Therefore, the inventor thinks, when leading-out portion 21 is aluminum, can make the surface passivation of leading-out portion 21, thereby improves anticorrosion ability.
When face forms thin film coated layer 22 on the top layer of this leading-out portion 21; For example can form thin film coated layer 22 through following technology: coating is dissolved with the non-crystalline polymer of the polyvinyl alcohol skeleton with hydroxyl of 0.2～6wt%, and (Japanese synthetic chemistry Co., Ltd. makes; The G polymer resin) and the aqueous solution of the charomic fluoride of 0.1～3wt% (III) trade name:; Further in baking oven, carry out heat drying then and cure; Make dried thickness reach about 0.1～5 μ m, and take place bonding and crosslinked.
Utilize the differential thermal analysis device to measure the result of the thermal change of thin film coated layer shown in Fig. 6; This thin film coated layer obtains through following technology: on the surface of predetermined test material; Coating is dissolved with the non-crystalline polymer of the polyvinyl alcohol skeleton with hydroxyl of 3wt%, and (Japanese synthetic chemistry Co., Ltd. makes; The G polymer resin) and the aqueous solution of the charomic fluoride of 1wt% (III) trade name:; In 200 ℃ of baking ovens, carry out heat drying further and handle, make dried thickness reach 3 μ m.And,, measured the thermal change of not carrying out the thin film coated layer of heat treated equally through baking oven as comparison other.Measure the result according to these, the fact that is not occurred peak value by fusing point in the thermal change of the thin film coated layer that carries out heat treated learns that the resin with polyvinyl alcohol skeleton of hydroxyl has taken place crosslinked.
So, when at the ironed film of the top layer of leading-out portion 21 surface layer coat 22, because the compressive resistance of thin film coated layer 22 is higher, even therefore reduce also can keep compressive resistance as the polypropylene layer of sealing material layer 23 or the thickness of polyethylene layer.Therefore, the moisture that inside lithium ion cell is infiltrated at the two ends (marginal portion) from the cross section that intersects vertically with its bearing of trend of leading-out portion 21 tails off, and the timeliness deterioration of lithium-ion battery electrolytes reduces, thereby the life of product of battery is elongated.
Further; Even infiltrate inside battery and electrolyte and moisture reacted cause under the situation of electrolyte decomposition generation hydrofluoric acid at the moisture of trace; Because it is less to be laminated to the free volume (emptying aperture, space that layer is interior) of the thin film coated layer 22 that resin or its copolymer resins by the polyvinyl alcohol skeleton with hydroxyl of the top layer face of leading-out portion 21 form; Therefore gas barrier property is high, can prevent that hydrofluoric acid is diffused into the outside along sealing material layer.And,, can prevent that also leading-out portion 21 is corroded through the passivating film that is formed on surface of aluminum plate even the hydrofluoric acid of trace contacts the surface of the leading-out portion 21 that is formed by aluminium sheet.Therefore, can keep the interlayer adhesive strength between leading-out portion 21 and the sealing material layer 23, can keep higher compressive resistance, can prevent the leak of liquid of battery etc.
Preferred 50～300 μ m of thickness of the sealing material layer 23 that engages in advance consider that water resistance most preferably is 50～150 μ m.When the thickness of leading-out portion 21 when 200 μ m are above, the sealing material layer 23 that the two ends (edge) in the cross section that intersects vertically with its bearing of trend that leading-out portion 21 may take place are located produces through holes, thus the situation that can't seal (sealing) electrolyte.Therefore, preferably, shown in Fig. 4 B, the two ends 24 in the cross section on the direction that intersects vertically with its bearing of trend of leading-out portion 21 are crushed, and it is thinner to make the thickness at two ends compare the cross section middle body.In view of the above, can reduce the thickness of the sealing material layer 23 of joint in advance.And, can also prevent that the sealing material layer 23 of the edge of leading-out portion 21 from through hole taking place.
Preferred 0.1～5.0 μ m of thickness of the thin film coated layer 22 that forms by resin or its copolymer resins of polyvinyl alcohol skeleton, more preferably 0.5～3 μ m with hydroxyl.When the thin film coated layer has this thickness, moisture-proof characteristic and adhesive strength performance are increased.
Thin film coated layer 22 is provided to the necessary part of leading-out portion 21 with pattern-like through printing process.That is to say, in the bonding part of the current-collecting member of inside battery and electrode cable member 18, the part that serial or parallel connection ground engages battery, do not form thin film coated layer 22.As mode of printing, can adopt known printing processes such as ink-jetting style, point gum machine (dispenser) mode or spraying method.And, be not only the top layer of leading-out portion 21, the two ends (marginal portion) from the cross section that intersects vertically with its bearing of trend of electrode cable member also need be printed.Therefore, preferred ink-jetting style of mode of printing or point gum machine mode.Especially, in the point gum machine mode, the dispense tip that the thin width about use is can be with 10mm wide prints is optimum mode.
Join the sealing material layer 23 preferred identical or similar resin films of resin film 13 (with reference to Fig. 2) that use with the innermost layer of the ironed film 10 of aluminium lamination that use of electrode cable member in advance to.When resin film 13 is normally used polypropylene; Sealing material layer 23 can be cast polypropylene (CPP) film, maleic anhydride sex change polypropylene single thin film or have the polypropylene single thin film that the monomer of epoxide functional groups carries out sex change with GMA etc., or these and polyacrylic plural layers.When resin film 13 is polyethylene; Sealing material layer 23 can be polyethylene, maleic anhydride sex change polyethylene or have the polyethylene single thin film that the monomer of epoxide functional groups carries out sex change with GMA etc., can also be the plural layers of these and polyethylene and copolymer thereof.At this moment, on sealing material layer 23 and surface that electrolyte contacts, can use maleic anhydride or acrylic acid copolymer, with polyethylene of sex change such as GMA etc.
The nonaqueous electrolyte battery that the present invention uses can be enumerated the battery that in electrolyte, uses organic bath as the lithium ion battery of secondary cell and double electric layer capacitor etc.As organic bath, generally use propene carbonate (PC), diethyl carbonate (DEC), ethylene carbonate etc. with the material of carbonates, but be not to be defined in this especially as solvent.
