Technical field
The utility model relates to a kind of tools of porous current collector, and in particular to a kind of collector foil perforator
Skill belongs to electrode material field.
Background technique
With the development of new energy industry, the fields such as electric car, number, energy storage achieve very fast development, therefore two
Primary cell is just playing increasingly important role.But current secondary battery still can not expire in energy density and power density
The demand of sufficient people, and collector of perforating is exactly an effective improvement approach.It is close that perforation collector can not only improve energy
Degree and power density, can also improve the cohesive force between anode and cathode slurry and collector.But conventional through-hole collector mesoporous
Foil is penetrated, when this is easy for causing coating sizing-agent the case where the material leakage of hole, to be unfavorable for using in actual production.Such as
If fruit perforation copper foil mesoporous does not penetrate foil, so that it may effectively solve the problems, such as this.
It refers to wear using corrosion treatment to prepare in utility model patent disclosed in Zhang Xianwen etc. (CN107130245A)
Hole foil, but on the one hand this method limits the production of foil, and different foils needs to prepare different corrosive liquid and corrosion process, and
Time-consuming for production technology, is unfavorable for producing in enormous quantities.It is mentioned in the far equal disclosed utility model patent (CN103531815A) of Xu Qi
Mask is made to printing technology, then makes the technique of perforated foil of wet etching technique, but the process is excessively complicated, no
With producing feasibility.Existing machinery punching technology aperture is not easy to control, and is difficult to make the collector of special pore size distribution as required.
Therefore, existing method needs to improve there are still defect.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of simple process, at low cost, suitable
Produce in enormous quantities, the tools for the porous current collector that aperture is controllable.
The utility model is achieved through the following technical solutions:
A kind of tools of porous current collector, including for fixing collector to be perforated(1)Pressing plate(3)With for wearing
The bundle plate in hole(2), the pressing plate(3)It is equipped with multiple holes.
Preferably, the pressing plate(3)It is porous sieve-type metal plate, and pressing plate(3)In hole be bevel edge hole.
Preferably, the bundle plate(2)There is the metal plate of several fine needles for single side.
Preferably, the pressing plate(3)Quantity be 2, and upper and lower two pressing plates(3)In fixation collector to be perforated(1)
The pore size of the upright position Shi Tongyi is inconsistent.
Preferably, the bundle plate(2)The length of upper fine needle is greater than single pressing plate(3)And collector(1)The sum of thickness.
Preferably, the pressing plate(3)The aperture of mesoporous is 50 ~ 500 microns.
Preferably, the collector(1)Material be at least one of copper, aluminium, nickel, titanium, silver, palladium.
Preferably, the collector(1)With a thickness of 5 ~ 35 microns.Further, the collector(1)With a thickness of
5 ~ 15 microns.
Preferably, the collector(1)Porosity ranges are 10% ~ 90%.Further, the collector(1)Hole
Rate range is 30% ~ 70%.
The beneficial effects of the utility model are:
The utility model simple production process, it is low in cost, it is suitble to industrial mass production.It is pushed down using porous pressing plate
The method of collector foil fixes collector, prevents collector from crumpling, controls collector by the pressing plate of special pore size distribution
Aperture can also produce the collector of different pore size by replacement different pore size pressing plate, be suitable for commercialization and produce in enormous quantities.
Detailed description of the invention
Fig. 1 is the utility model porous current collector tools main view.
Fig. 2 is the top perspective view of the utility model pressing plate.
Fig. 3 is the utility model collector perforation flow diagram.
Fig. 4 is the schematic top plan view after the production of the utility model porous current collector.
Appended drawing reference:1- collector, 2- prick plate, 3- pressing plate, 4- fine needle, 5- collector punch block.
Specific embodiment
To be best understood from the utility model, the utility model is further described below with reference to examples and drawings, with
Lower embodiment is only to be illustrated to the utility model rather than be limited to it.
Mainly include three parts as shown in Figure 1, a kind of tools of porous current collector, respectively bundle plate 2, pressing plate 3 with
And perforation collector 1.Pricking plate 2 is the metal plate that one piece of single side has many fine needles 4, is mainly used for the perforation of collector 1.Pressing plate 3
It is one piece of porous sieve-type metal plate, as shown in Fig. 2, 3 mesoporous of pressing plate uses bevel edge hole, i.e., aperture is different up and down, the work of pressing plate 3
With being on the one hand to fix collector 1, prevents collector 1 in perforation procedure from crumpling, on the other hand can also control in collector 1
The size in aperture.
Fig. 3 is practical puncture process flow diagram flow chart, is that upper lower platen 3 clamps 1 foil of collector first, then pricks plate 2 and declines,
Fine needle 4 passes through collector 1, and when diameter and 3 aperture of pressing plate of needle are mutually simultaneously stopped, bundle plate 2 returns to original position, thus in collector 1
Upper formation micropore, then pressing plate 3 returns to original position, and collector 1 moves a certain distance, repeats the above steps and realize flow line production,
Whole process is completed.Fig. 4 is the porous current collector top view to complete, wherein including punch block and puncherless area(It can be by
Whether there is or not puncherless areas for actual demand design).
The material of collector is at least one of copper, aluminium, nickel, titanium, silver, palladium, with a thickness of 5 ~ 35 microns, porosity ranges
It is 10% ~ 90%.Aperture is 50 ~ 500 microns in pressing plate, and the aperture of collector can be controlled by the pressing plate of special pore size distribution, may be used also
To produce the collector of different pore size by replacement different pore size pressing plate, it is suitable for commercialization and produces in enormous quantities.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
