Description
Technical field
The present invention relates to the aluminium foil of lithium battery, Copper Foil processing technique field, enter in particular to aluminium foil, the Copper Foil of lithium battery
The punch device of row punching.
Background technology
The positive and negative pole material of lithium battery is aluminium foil, Copper Foil, and the base material of the most the most frequently used lithium battery positive and negative pole material is double
The smooth aluminium foil in face, Copper Foil, basic production technique is to impose the bag rich in lithium ion to starch, at Copper Foil base on the surface of Al foil substrate
The surface of material imposes the graphite material rich in electronics, is bonded through weight.This two-sided smooth aluminium foil, copper foil base material have
Have clearly disadvantageous, i.e. surfacing (bag slurry, graphite) adhesive strength is limited, easy to fall off, directly affects the use longevity of lithium battery
Life, simultaneously, it is impossible to adapt to the use environment of special state (high temperature, low temperature).
It is desirable to porous foil, i.e. getting intensive aperture on aluminium foil, Copper Foil, this porous foil is as lithium electricity
The both positive and negative polarity base material in pond has two significant advantages, and one is that surfacing (bag slurry, graphite) adhesive force is strong, difficult drop-off, and two
It is that the capacity of battery dramatically increases.Porous foil can form two kinds of faying faces when bag slurry covers, and one is that bag slurry is direct with foil
In conjunction with, two is bag slurry through higher directly in conjunction with intensity directly in conjunction with, bag slurry of the bag slurry of aperture and opposite side, thus significantly carries
The high adhesive strength of surfacing, difficult drop-off, it is suitable for the use environment of special state (high temperature, low temperature) simultaneously.Due to
Foil is with intensive aperture, and these apertures are all filled by bag slurry, so, the total amount of bag slurry dramatically increases, and the capacity of battery carries
High 20-40%.
Foil punching has high technology requirement, it is desirable to pore size is consistent, and uniformly, burr is minimum, concrete skill in arrangement
Art index see table:
| Aluminium foil | Copper Foil | |
| Base material thickness | 20-30um | 8-20um |
| Aperture | 0.3-1mm | 0.2-1mm |
| Porosity | 20%-40% | 20%-40% |
Burr size: ＜ 5um
Porous foil technology of preparing Japan grasps, and the most successfully produces in batches, is mainly used in high end cells manufacture, but
This product is not sold to China, and implementation of China is also blocked by technology, technique.The most domestic there is no possesses the factory producing porous foil
Family, existing producer is carrying out the research of technique of this product, uses needle-punching method, but the distribution in hole is irregular, especially hair
Thorn size is bigger, it is difficult to meets and uses requirement.
Summary of the invention
It is an object of the invention to overcome weak point of the prior art, it is provided that the aluminium foil of lithium battery, Copper Foil carry out beating
The punch device in hole.
For achieving the above object, the present invention adopts the following technical scheme that:
The aluminium foil of lithium battery, the punch device of Copper Foil, described punch device includes frame, pressure pump, water cutter, sets
The cutting upper mold of porous, also includes feeding roller, transfer roller, punching lower die workbench, and water pressurization is sent into water cutter by pressure pump, will
Aluminium foil or the feeding roller of Copper Foil, send into punching lower die workbench by transfer roller, and the water under high pressure of water cutter is by cutting the hole of upper mold
To sending into punching lower die workbench, paper tinsel or Copper Foil are punched.
Water is pressurized to 100～400MPa by described equal pressure pump.
Described equal pressure pump is mixed into Punica granatum L. sand in water under high pressure.
The beneficial effects of the present invention is: the present invention uses the cutting die of water cutter and porous, it is possible to high efficiency to aluminium foil,
Copper Foil drilling operation, punch distribution rule, substantially without burr, it is possible to meets high end cells manufacture to aluminium foil, the porous of Copper Foil,
Battery capacity is provided and improves battery life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the punch device of the present invention.
Detailed description of the invention
Below in conjunction with each specific embodiment and Figure of description, the invention will be further described:
As it is shown in figure 1, the punch device of the aluminium foil of lithium battery, Copper Foil, described punch device includes frame, pressure pump
1, water cutter 6, set the cutting upper mold 2 of porous, also include feeding roller 4, transfer roller 3, punching lower die workbench 5, pressure pump 1 will
Water cutter 6 is sent in water pressurization, and aluminium foil or Copper Foil are sent into punching lower die workbench 5 by transfer roller 3 by feeding roller 4, and transfer roller 3 can lead to
Crossing motor drives it to rotate, and the water under high pressure of water cutter 6 is by cutting the hole of upper mold 2 to sending into punching lower die workbench 5 to paper tinsel or copper
Paper tinsel punches, and this some holes pore size is consistent, and uniformly, burr is minimum in arrangement, equal pressure pump 1 water is pressurized to 100～
400MPa, high-pressure water knife quickly enters cutting upper mold 2, quickly punches paper tinsel or Copper Foil, and process time is short.All pressure (hydraulic) waters
Pump 1 is mixed into Punica granatum L. sand in water under high pressure, and material cutting loss is considerably less, and cutting force is little decreases auxiliary operation, impulse-free robustness.
Through test, use institute of the present invention punched hole parameter such as following table, surfacing (bag slurry, graphite) attachment can be strengthened
Power, difficult drop-off, increase the capacity of battery.
| Aluminium foil | Copper Foil | |
| Base material thickness | 25um | 15um |
| Aperture | 0.6mm | 0.5mm |
| Porosity | 37% | 37% |
The above is only to presently preferred embodiments of the present invention, is not defined the scope of the present invention, therefore is not taking off
On the premise of the present invention designs spirit, this area ordinary skill technical staff is to structure of the present invention, feature and principle
The equivalence change done or decoration, all should fall in the protection domain of the present patent application patent.
