Description
Technical field
The present invention relates to a kind of Graphene coated aluminum foil apparatus for coating.
Background technology
New and renewable sources of energy technology is five technology having most in 21 century development of world economy and determining impact
One of field.Disposable the in short supply of the energy such as oil has become undisputable fact, this give new and renewable sources of energy technology and
Product brings the market space of unlimited development.The conversion of new and effective energy is meeting modern society to new forms of energy with storing technology
Demand is occupied critical role.
Lithium secondary battery, as a kind of high power capacity, long-life energy-storage system, obtains in small-sized portable electronic product
It is widely used, and its application prospect in high power electrokinetic cell and Large Copacity energy-storage battery more attracted global mesh
Light.The research and development of high performance lithium ion battery are vital tasks in electrochemical energy storage field.
In the lithium secondary battery, active material is spread evenly across aluminium foil or copper foil current collector surface, collector by with work
The electronics that electrochemical reaction produces is collected and derives to external circuit by the physical contact of property material, thus realizes chemical energy and be converted into
The process of electric energy.Thus can deduce, contacting between collector with active material is the important shadow of lithium ion battery charge-discharge performance
The factor of sound.
Therefore, foil becomes the important component part of lithium secondary battery, although present lithium secondary battery Performance comparision is excellent
More, but in the lithium secondary battery pole piece processing technology of routine, active material slurry is directly coated at aluminium foil or copper foil surface, dry
Realize active material by binding agent after dry and be fixed on collection liquid surface.
Solve at present this problem way mainly by increasing the consumption of slurry binding agent, by foil surface chemistry
Burn into corona or process foil in the foil surface coating method such as thin layer containing conductive material and increase adhesion energy between the two
Power.But battery performance can be caused a series of harmful effect, including increase, the energy of the internal resistance of cell by the increase of consumption of binder
Metric density and the reduction of power density, service life cycle shorten, battery-heating amount rising etc..Chemical attack, corona etc. are special
Place is comprehended the foil a certain degree of surface damage of generation, reduces the intensity of foil, has a strong impact on follow-up phenomenon processing, and
Relatively costly, it is unfavorable for the needs of large-scale production.And at the foil surface-coated thin layer (coated aluminum foil) containing conductive material, should
Thin layer needs good conductive capability, higher specific surface area, excellent adhesive property, and has relative to metal collector
There is more preferable deformability, thus increase the conductive contact between active material and foil, reduce interface resistance, and improve between the two
Adhesion strength, the method preparation technology is relatively easy, and processing cost is the cheapest.
At present, it is a kind of generally acknowledged breakthrough for utilizing conducting function coating conductive base (aluminium foil) carries out surface to process
Innovative technology.This technology except the cohesive force of active material and collector can be improved, reduce pole piece manufacturing cost, also have with
Lower advantage: (1) reduces battery polarization, improves multiplying power and gram volume, promotes battery performance；(2) protection collector, extends battery and makes
Use the life-span；(3) significantly improve the use concordance of set of cells, set of cells cost is greatly reduced.Therefore, coated aluminum foil is used to substitute
Tradition aluminium foil uses in dynamic lithium battery and has become as a kind of important trend.
In above-mentioned collection liquid surface coating thin layer, the selection of conductive material is undoubtedly most important link.From conduction
Performance and cost consider, and material with carbon element is optimal selection.Material with carbon element is of a great variety, common are graphite, carbon black, carbon are received
Mitron, carbon fiber etc..The most much it is applied in the example of conductive coating, such as Henkel KGaA, Japan Showa electrician
Deng enterprise, they apply one or more material with carbon element mixture by aluminium foil surface and improve contacting of collector and active material
Area and cementability, but due to the restriction of conventional carbon particle diameter, applied thickness is under some influence, and above producer is sold
Conductive coating thickness (two-sided) is generally 2 ~ 5 m, causes battery energy density to reduce, and the contacting of conventional carbon and aluminium foil
Less, in use, through discharge and recharge repeatedly, pole piece active substance can gradually expand, cause contact area by
The fewest, cause properties to be gradually reduced.Nano-graphite is to prepare through special process method, and purity is high, and granularity is little and uniform,
Lamella is thin, and surface activity is high, and it has superior electric conductivity, greasy property and resistance to elevated temperatures.From its structure and physical property
Can analyze, use nano-graphite as conductive coating, owing to nano-graphite specific surface area is big, and be lamellar structure, with aluminium foil
Base material contact surface is more, uses the aluminium foil adhesive property of such material modification to be greatly improved, can effectively suppress conventional carbon material
Produced by expand to disengage from phenomenon, and its electric conductivity is the most excellent, and other conductive material relatively has more advantage.
In order to obtain more preferable nano-graphite coated aluminum foil, it is desirable to provide corresponding manufacturing and processing equipment.Existing coating
There is more defect in device, it is impossible to produces high-quality nano-graphite coated aluminum foil.
