Embodiment
Mainly in conjunction with the drawings and the specific embodiments collector is described in further detail with perforated foil and preparation method thereof below.
As shown in Figure 1, the collector of an execution mode comprises the steps: by the manufacture method of perforated foil
Step 1: ink is mixed and obtains diluting ink according to the ratio of mass ratio 100:3～8 with slow curing water.
Step 2: use dilution ink evenly to print one deck ink mask layer 120 at a side surface of clean metal forming 110, opposite side surface printing one deck is by the ink mask pattern 130 that dilutes ink and form, dry after solidifying, obtain the metal forming 100 that ink adheres to, wherein, ink mask pattern 130 is mesh-like structure.
Clean metal forming 110 can obtain by metal forming is carried out to oil removing and/or pickling processes successively, for example, metal forming can be carried out to ultrasonic solvent (as trichloroethylene solution and/or absolute ethyl alcohol) and clean, and removes the pollution of metal foil surface.
In the present embodiment, above-mentioned manufacture method is also included in the step of before printing dilution ink, clean metal forming 110 being carried out to surface coarsening processing, specifically comprises the steps:
It is that the sulfuric acid solution pickling of 100～150g/L was taken out after 2～5 minutes that clean metal forming is placed in to concentration, the mixed solution that is placed in again the sulfuric acid that ammonium persulfate that concentration is 130～170g/L and concentration are 8～12g/L soaks after 1～3 minute and takes out, after dry, with nitrogen, blow 3～10 minutes, obtain the clean metal forming of surface coarsening.Clean metal forming 110 is carried out to surface coarsening processing and can strengthen the adhesive force between follow-up ink mask layer 120 and ink mask pattern 130 and metal forming 110 surfaces, thereby further improve the uniformity that subsequent etching is processed.
In the present embodiment, clean metal forming 110 can be Copper Foil or aluminium foil.By Copper Foil, make and obtain the negative pole that perforated foil can be used as energy storage device, by aluminium foil, make the positive pole that the perforated foil obtaining can be used as energy storage device.
The thickness of ink mask layer 120 and ink mask pattern 130 is 10 μ m～20 μ m.As shown in Figure 2, ink mask pattern 130 is mesh-like structure, the shape of its mesh can be the various shapes such as circular, square, hexagon, but maximum diameter of hole R is less than 200 μ m, and porosity (volume of ink mask pattern or perforated foil internal void accounts for the percentage of its cumulative volume) is greater than 20%.The porosity of ink mask pattern 130 is relevant with the thickness of metal forming 110, generally, metal forming 110 thickness are thicker, porosity can be higher, metal forming 120 is thinner, porosity needs lower, and for the metal forming 110 of specific thicknesses, porosity need to be controlled in certain scope to guarantee that the mechanical strength of the follow-up perforated foil obtaining 210 can meet the needs of actual production.Mesh on ink mask pattern 130 is uniformly distributed, and mesh cycle T is 300～500 μ m, and alternate angle β is 30 °～60 °.
What present embodiment was used in metal forming both side surface printing dilution ink process is screen printing mode.The process that is cured processing to being printed with the metal forming of ink mask layer and ink mask pattern is to use ultraviolet ray irradiation ink mask layer and ink mask pattern that ink mask layer and ink mask pattern are solidified.
Step 3: the metal forming 110 that ink is adhered to is placed in etching liquid and carries out etching processing forms perforation in metal forming 110, obtains the perforated foil 200 that ink adheres to.
Etching liquid is generally comprised of principal component, dispersant and defoamer, and wherein, if metal forming is Copper Foil, the principal component of the etching liquid of corresponding Copper Foil is ferric chloride solution, hydrogen peroxide-sulfuric acid solution, ammonium persulfate solution or acid chlorization copper solution.If metal forming is aluminium foil, the principal component of the etching liquid of corresponding aluminium foil is phosphoric acid solution, salpeter solution or acetum.Dispersant can be the organic dispersing agents such as triethyl group hexyl phosphoric acid, lauryl sodium sulfate, methyl anyl alcohol, cellulose derivative, polyacrylamide, guar gum, fatty acid polyethylene glycol ester and polyethers nonionic surface active agent (as OP dispersant etc.), or the inorganic dispersant such as sodium phosphate trimer, calgon and sodium pyrophosphate.Defoamer can be ethanol, polyoxypropylene, polyoxyethylene or polyoxy propyl alcohol amidogen ether etc.
Step 4: the ink mask layer of a side surface and the ink mask pattern on opposite side surface of the perforated foil 200 adhering to except removal ink, obtain perforated foil 210 after cleaning and be dried processing.
