Description
Technical field
The present invention relates to electronics paper tinsel technical field, specially a kind of inexpensive perforated foil preparation method.
Background technology
The perforated foil of electron level is mainly used in the afflux of super capacitor, lithium ion battery, electrokinetic cell, Ni-MH battery
Body, can be used with optical reflecting layer and using aluminium foil, copper foil as substrate coating.
Perforated foil is broadly divided into food packaging and electronics and used, and food packaging perforated foil system is with 1235 ... etc..Double zero aluminium
Paper tinsel is completed using punch pattern mostly as rapidoprint.Because its intensity is relatively poor, purity is relatively low, and for aperture and
Away from requiring relatively low, it is impossible to supply battery, electric capacity coating and use.
Electronics perforated foil as super capacitor, lithium ion battery and electrokinetic cell collector when, be graphite mix in advance lithium and
The key of electroactive material filling, the duct that perforated foil is provided makes lithium source (lithium metal or lithium-containing compound) short in external circuit
In the case of road, rapidly and uniformly to negative pole doped lithium ion (the high-capacity lithium-ion electricity of stacking or winding positive pole and negative pole
Container).The electric current that electroactive material generation can be carried collects to form larger current versus output, and offer is covered
Power and reduction afflux body weight, increase the power and energy of unit intensity.Therefore porosity and distribution density, hole shape size, is yes
The no key used suitable for cell coating.Between the optimal 0.5~100um of size in perforated foil aperture
Existing perforated foil processing mode has：Punching processing, etching process and the etching of template die assisted electrochemical.
Presently relevant exploitation and production company-Mitsui metal, foliation Co., Ltd., metal industry Co., Ltd., east
Yang Lv Co., Ltd..
Etching process is divided into photoetch (using light shield), electrolytic etching and laser-induced thermal etching.
The method that photoetch makes perforated foil in the high-volume of Japanese Patent Publication in 2011 first, process uses intaglio process
Brush, the mode such as hectographic printing and screen painting is used in one layer of photoresist of metallic film surface even spread, then in the way of light shield
Ultraviolet light forms desired image on photoresist, then to etch shape needed for corrosion, typically the perforated foil of making in this way
Aperture is all in below 100um.
Electrolytic etching processing is come control punch by control electric current waveform, with liquid composition, temperature change and reaction time
The graphics shape of paper tinsel.Perforated foil aperture of the institute using base material prepared by high voltage anode aluminum foil is about 1~100um, is then also needed
Remove the insulating oxide aluminium lamination on surface.
Laser-induced thermal etching can prepare smaller perforated foil, but the contraposition of laser-induced thermal etching requires high, and etch depth has
Limit, easily causes not perforated phenomenon, and relative cost is higher, cry not matters largely produce.
Template die assisted electrochemical deposition processes, its processing mode includes：1. it is that to make template its template can be monodisperse sphere
The bubble hydrogen produced in body, high current density electrodeposition process；2. deposition precursor thing-use chemistry or electrochemistry in template
Predecessor is inserted in space and carry out solidification 3. by mode goes removing template to obtain perforated foil.
Punching handling process is simple, is of relatively low cost, and is the mode for being relatively adapted to largely produce at present.
But, also there is the defect of pigeon in actual production in above preparation method：
Photo-engraving process must first be coated with one layer of photoresist on aluminium foil, and required hole shape is designed in the mode by light shield,
Corroded, then washing away unnecessary photoresist.If need to largely produce.Coating, contraposition light shield need to be first passed through, etching tank is reentered
And last organic solvent cleaning.To avoid the influence of facility environment to each other, three big sections of coating contraposition light of process 1. need to be divided into
Cover 2. aluminium foil corrosions 3. and remove photoresist and drying.Each section harsh with respect to general corrosion to environmental demand.And because of aluminium foil corrosion medicine
Three sections and a continuous production should not be caused board maintenance burden by agent relation.
Electrolytic etching method process need to equally be divided into three roads, be specially：1. anode processing, 2. chemistry or electrochemical corrosion,
3. corona or (electricity) chemical method remove oxide, and last road processing procedure easily causes uneven influence in handling process and subsequently made
With.
Laser-induced thermal etching can prepare smaller perforated foil, but the contraposition of laser-induced thermal etching requires high, and etch depth has
Limit, easily causes not perforated phenomenon, and relative cost is higher, cry not matters largely produce.
Template die assisted electrochemical deposition processes, its template die makes and quantization is one and needs the processing procedure of time management and control, and
Fill the uniformity and go the mode of removing template connect make this processing procedure difficulty increase.
Punching handling process is simple, is of relatively low cost, and is the mode for being relatively adapted to largely produce at present, and its quality critical exists
In mould, generally processing perforation prepare the piercing die limit about in 100um, typically then all fall in more than 300um, xm and, after punching
Aluminium foil flash is had around hole, it is therefore desirable to the process of Burr removal.General punch die needle point is all in more than 300um, hole
Smaller, needle point is thinner, can not meet the intensity of punching, about 100/180 beat/min of general frequency.
