Description
Technical field
The present invention relates to the preparation methods of the coating film of low-inensity radiation, and in particular to one kind can be used for lithium battery, lithium from
The preparation method of the coating film of sub- battery, polymer battery and supercapacitor belongs to the technical field of battery diaphragm preparation.
Technical background
Diaphragm is the important component of lithium ion battery.In battery system, diaphragm plays prevention electronics between anode and cathode
The effect of connection and conducting ion.Diaphragm has important role to battery performance and safe handling.According to the difference of production technology,
Diaphragm can be divided into film by dry method, wet process film and composite membrane.The application range of diaphragm based on polyolefine material is most wide.
In abuse conditions, lithium ion battery may be warming up to 100~300 DEG C of high-temperature region.Due to polyethylene (PE), gather
Propylene (PP), polyolefin composite film (e.g., PP/PE/PP, PE/PP) at high temperature can contraction distortion, using polyolefin film lithium from
There are security risks for sub- battery.The coating diaphragm of the preparations such as coating alumina on polyalkene diaphragm, hence it is evident that improve heat resistance
Can, thus, ensure the safety that battery uses.Coating diaphragm is generally made of basement membrane, adhesive and inorganic nano material.
From the point of view of adhesive, coating diaphragm generally use PVDF resin [Hennige V., et al. US 7790321,
2010. 7. 9.], polymethyl methacrylate (PMMA) [Zhao Jinbao etc., Chinese invention patent, 103035866 A of CN,
2013.4.10.], butadiene-styrene rubber (SBR) [Park J. H., et al. J. Power Sources, 2010,195
(24): 8306-8310.], silica solution [Lee J. R., et al. J. Power Sources, 2012,216:42-
47.] and Kynoar-hexafluoropropene (PVDF-HFP) [Jeong H. S., et al. Electrochim. Acta,
The binders such as 2012,86:317-322.].Sohn etc. is by polymethyl methacrylate (PMMA), Kynoar-hexafluoro third
Alkene (PVDF-HFP) and nanometer Al2O3Mixture [Sohn J. Y., et al., J. Solid State
Electrochem., it 2012,16,551-556.] is coated on PE film, is prepared for PVDF-HFP/PMMA coating diaphragm.
Adsorption theory thinks, bonding is between two kinds of material molecules caused by contact and interfacial force.The main source of bonding force
It is intermolecular force (including hydrogen bond and Van der Waals force).Adhesive and continuously contacting with for adherend referred to as soak, and to obtain good
Good bond effect requires the surface tension of binder less than the surface tension of adherend.Untreated polymer (such as poly- second
Alkene, polypropylene) surface inertia it is larger, be difficult to be bonded.
Jeong etc. [Jeong H. S., et al. Electrochim. Acta, 2012,86:317-322.]
Studies have shown that the ratio regular meeting of Kynoar-hexafluoropropene (PVDF-HFP) binder and coated particle to coating diaphragm
Performance generates significant impact.The dosage for increasing binder in coat can reduce falling off for coated particle, and it is mechanical to improve diaphragm
Performance.But, the surface nature of basement membrane can be changed by the coated particle that binder coats, reduce the wetability to electrolyte, it is right
The high rate during charging-discharging of battery is unfavorable.Song etc. [Song J., et al. Electrochim. Acta, 2012,
85:524-530.] it finds, binder can make the particle packing of nanometer coating agent in the duct of basement membrane, reduce the hole of diaphragm
Rate increases the resistance of lithium ion cross-film diffusion.
From the point of view of coat, the inorganic material studied includes nanometer Al2O3、ZrO2、SiO2、TiO2、MgO、CaO、
CaCO3、BaSO4, zeolite, boehmite, clay etc..[Takemura D., the et al. J. Power such as Takemura
Sources, 2005,146 (1/2): 779-783.] investigate Al2O3Influence of the partial size to membrane properties.They have found, apply
Cover Al2O3The high temperature resistance of diaphragm can be improved.Choi etc. [Choi E. S., et al. J. Mater. Chem.,
2011, (38): 14747-14754.] use partial size 40nm SiO2PE microporous barrier is coated, coating diaphragm is prepared for.Special duct
Inorganic material be also used for replace nanometer Al2O3As coating agent, in the battery system using this coating diaphragm, solvent
The lithium ion of change can provide " green channel " along inorganic particle and directly transmit.
From the point of view of basement membrane, since the reactivity of polyolefin-based film surface is little, the coat and basement membrane on diaphragm are coated
Between bond defective tightness.During long-term charge and discharge cycles, the coat for coating diaphragm is easy to fall off.It is existing in order to improve this
As [Chen H., the et al. Plasma activation and atomic layer deposition of such as Chen
TiO2 on polypropylene membranes for improved performances of lithium-ion
Batteries, J. Membr. Sci., 2014,458,217-224.] PP film surface first is handled with plasma technique,
Then it is coated with TiO2, coating diaphragm is made.Studies have shown that corona treatment can generate polar group in PP film surface, have
Conducive to TiO2In the dispersion of membrane surface.The diaphragm of preparation imbibition rate with higher and ionic conductivity, lower thermal contraction
Rate.The lithium ion battery of assembly discharge capacity with higher and preferable multiplying power discharging property.
Although coating diaphragm by above-mentioned study on the modification in battery system and there are some problems.For example, coating diaphragm
It will increase the internal resistance of cell, discharge capacity of the cell made to be difficult to bring into play.Coat the coat and anode, cathode, electrolyte of diaphragm
There are problems that whether matching.
In order to solve the problems, such as coating diaphragm application, the compound of the key containing P-O is added in the present invention in coat,
By the compound of the key containing P-O and reacting for the polyolefin base membrane of corona treatment, the painting with the valuable key connection of basement membrane is formed
Coating significantly improves binding force between coat and basement membrane in coating diaphragm, reduces the internal resistance of cell, promotes the electric discharge of the battery of assembly
Capacity gives full play of, while reducing picking phenomenon.Since the wetability of the compound of the key containing P-O is stronger, to electrolyte
Affinity is strong, and imbibition ability is strong.It is good with the matching of anode, cathode, electrolyte, hence it is evident that improve the performance of coating diaphragm.
