Description
Technical field
The present invention relates to copper foil repairing fields more particularly to a kind of ray type copper foil to overhaul correction technique.
Background technique
Currently, major part lithium ion battery producer all uses electrolytic copper foil as the negative current collector of lithium battery both at home and abroad,
Copper foil had both served as the carrier of negative electrode active material in lithium battery, and served as collection and the transmission body of cathode electron stream, therefore electricity
Tensile strength, extensibility, compactness, surface roughness, the thickness uniformity and presentation quality of copper foil etc. is solved to lithium ion battery
The chemical property of cathode manufacture craft and lithium ion battery has very big influence.
Since lithium battery copper foil is in aspect of performance, it is desirable that copper foil is few with defect, crystal grain is thin, good in oxidation resistance, folding resistance
Good, the features such as surface roughness is low, tensile strength is high and ductility is high, therefore, lithium battery copper thickness, indicated weight, tensile strength,
The needs such as room temperature elongation percentage, roughness touch the mark.
Electrolytic copper foil accounts for the 5%-8% of lithium battery cost as cathode of lithium battery collector, and copper foil is to produce dynamic lithium battery not
Can or one of scarce critical material, the superiority and inferiority of quality directly influences battery process and performance.6 μm of lithium ion batteries are new energy
Source automobile, using smart phone as the core material of the products batteries such as the 3C industry of representative, laptop, ESS energy-storage system, space flight
Material.But the technology in this field is monopolized by states such as the U.S., Japan, South Korea for a long time, currently, the pursuit of lithium electrolytic copper foil product is lightening
As trend.As the application amount of 6 microns of lithium electrolytic copper foils is increasing increasingly, aluminium foil products are in micron progress from 8 microns to 6
Transformation.The feature of 6 micron copper foils maximum be it is thin, this allows many copper foil manufacturing enterprises to hang back, and can play 6 micron copper foil advantages
Battery enterprise it is very few.
It is broken out the driving power battery market demand by new-energy automobile to increase, lithium electrolytic copper foil production capacity is well sold and in short supply, from technical standpoint
For, power battery enterprise is to meet downstream course continuation mileage demand, cost efficiency, to the demand trend of the slimming of lithium electrolytic copper foil
It grows in intensity, compared to 8 μm lithium electrolytic copper foils, 6 μm of product is the hot spot that power battery enterprise competitively chases instantly, but from reality
From the point of view of applicable cases, 6 μm of lithium electrolytic copper foils do not reach expected but in the application of power battery enterprise, first is that the country can be steady
It is few quantitatively to produce 6 μm of copper foil enterprise；Second is that encounter disconnected foil, cross cutting copper powder etc. in importing process more for power battery enterprise
A technical problem needs to solve.Currently, the stage of 6 μm of lithium electrolytic copper foil positive values " that thing which is rare is dear ", but in fact, up to the present
It can stably produce and 6 μm of lithium electrolytic copper foil enterprises for meeting the performance requirements such as power battery enterprise high flexibility, high resistance to compression count on one's fingers
Denumerable, production capacity supply in market is limited.In addition to this, power battery enterprise import 6 μm of process be also far from the industry it is expected that
Fast, the thickness of 6 μm of lithium electrolytic copper foils understands from copper foil enterprise and battery enterprise just like 1/10th of a piece hair of the mankind
It arrives, power battery enterprise from so frivolous copper foil was not used, all meets with before this in links such as coating, cross cutting, cold pressing, bakings
Not small challenge.For example currently, cutting away copper powder is exactly a difficult problem for enabling power battery enterprise headache the most.
Copper foil in lithium battery will cause very big influence: 1. rough surface big electrolytic copper foil and stone to lithium battery performance
The contact of the negative electrode active materials such as ink is poor, is also easy to produce falling off for coating active material, directly affects battery life；2, work as copper foil
When tensile strength is higher, copper foil is harder, and during will carry out roll containing the cathode of graphite active material, copper foil is without enough
To adapt to active material surface characteristic, the contact performance of the two is deteriorated for deformation；On the contrary, easily making electrode size when tensile strength is lower
Stability and planarization are deteriorated, and are also easy to produce copper foil fracture.These will lead to negative electrode material decrease in yield, influence battery capacity,
Internal resistance and service life；3, the copper foil of high-performance lithium battery must have enough elongation percentage, if elongation percentage is low, the copper in roll process
Foil will generate internal stress, divide, and influence battery capacity etc.；4, must be clean, smooth for the copper foil appearance of lithium battery, no
Allow to there is any striped, surface indentation, spot and machinery to pull, copper foil adhesive force is otherwise easy to cause to decline, coating is leaked
Foil point, two sides coating weight differ；5, the thickness uniformity has a direct impact negative electrode active material coating weight.
Because defective copper foil is used on lithium ion battery, lithium ion battery is easy breakdown, can generate explosion danger,
The danger of generation can be greatly reduced in repairing copper foil defect, during cell electrochemical reaction, because of the surface evenness of copper foil
It is relatively high, it is not easy to generate the excessive situation of local corrosion.
Based on the above situation, it is necessary to which the technique for studying a kind of copper foil repairing correction guarantees the quality of copper foil.
