Description

A kind of dielectric film containing amphion full solid state polymer and preparation method thereof and Purposes
Technical field
The present invention relates to a kind of dielectric film containing amphion full solid state polymer and its production and use.
Background technology
With the development of social economy, people increasingly increase to the demand of the energy, while dirty in global warming, air The problems such as contaminating serious is especially prominent, drastically influence the development and existence of human society, therefore this height of lithium rechargeable battery The green mobile energy storage device of effect is shown one's talent, and becomes the Main way of Future New Energy Source development, and current lithium ion battery is not only It is widely used in the mobile electrons such as smart mobile phone, notebook computer, stereo set, game machine, digital camera, palm PC to set It is standby, also more and more it is applied to the aspects such as electric automobile, unmanned plane, earth orbital flight device, airline carriers of passengers.
The lithium ion battery main Bian carbonates liquid electrolyte systems sold in the market, although have higher Ionic conductivity, but organic solvent has the characteristic such as easy leakage, relatively low flash-point, easy firing, volatile, poisonous, in mistake Fill, collide, extruding etc. in particular cases, it may occur however that reveal, burning, the security incident such as blast, the personal property to user Safety causes certain threat, it would therefore be highly desirable to it is higher and disclosure satisfy that all solid state poly- of business application to develop security performance Polymer electrolyte.
The room-temperature conductivity of full solid state polymer electrolyte (SPE) is relatively low, is the master that cannot meet commercially use requirement Want reason.PEO is the most frequently used polymer electrolyte at present, but conductance is relatively low under PEO and lithium salts mixed room temperature, is needed Further to be modified, improve the electrical conductivity under polymer room temperature.At present, the main method for improving electrical conductivity has grafting, blending, is total to The methods such as poly-, addition inorganic filler.As PHMS segments are soft, motility is good, PEO is grafted to PHMS side chains, not only may be used To reduce PEO crystallinity, and the advantage that PHMS sub-chain motions can be utilized good, the electric conductivity of PEO segments is further improved, Amphion is introduced into PHMS side chains further, new lithium ion mobility passage not only can be formed, improve electrical conductivity, Er Qieke By improving cell interface performance, to play a part of to improve electrochemical stability, therefore prepare electric conductivity and stability is equal The polymer dielectric film of the lithium ion battery applications for requiring can be met.
The content of the invention
The invention aims to solve that existing full solid state polymer electrolyte room-temperature conductivity is low, electrochemical window not High problem.The invention provides a kind of dielectric film containing amphion full solid state polymer and preparation method thereof and use On the way.
The full solid state polymer electrolyte film of the present invention is prepared by following steps:
Preparation method containing amphion full solid state polymer electrolyte is comprised the following steps:
A, by hydrosilylation, prepare side chain while being grafted PEO and zwitterionic poly- (methyl hydrogen silicomethane), Shown in its structure such as formula (1):
M/n≤0.04 in formula (1), x=3~20, R are-N (CH3)2-。
B, the polymer prepared in step a and lithium salts, crosslinking agent be dissolved in into acetonitrile or acetone solvent, stirred under room temperature Mix, pour into after being well mixed in Teflon mould, be placed in heat drying in vacuum drying oven, be crosslinked film forming, prepare containing Zwitterionic full solid state polymer electrolyte film.
Preferably, described step a is specific as follows:
1) PHMS is sufficiently mixed with organic solvent and obtains solution A, subsequently DMAA, PEO, catalyst and organic solvent are mixed Close uniform, obtain solution B, solution A is preheated to into 40~60 DEG C, under inert gas atmosphere, solution B is slowly added dropwise in A, drip Plus rear mixed liquor continues 2~3h of reaction at 40~60 DEG C, then raise temperature to 70~90 DEG C of reactions and disappear up to C=C, reaction terminates Organic solvent is removed, product C is obtained;
2) product C is sufficiently mixed with organic solvent and obtains solution D, in inert gas environment, be preheated to 45~60 DEG C, will During 1,3- propyl group sultone adds solution D, react 16~20 hours at 45~60 DEG C, remove organic solvent and obtain product E, product E is formula (1) structure.
Preferably, the step 1) in DMAA and PEO molar ratio≤0.04;Step 1) described in organic solvent be Toluene, step 1) catalyst is chloroplatinic acid, is fed intake as 10~40ppm, preferred chloroplatinic acid catalyst feeds intake as 20ppm.
Preferably, step 2) described in organic solvent be tetrahydrofuran;Add the amount and right of 1,3- propyl group sultone It is required that the DMAA added in 2 meets mol ratio for 1:1.
Preferably, lithium salts used is bis trifluoromethyl sulfimide lithium, lithium salts amount used and PEO satisfactions [EO] for adding: [Li+]=5~40.
Preferably, added crosslinking agent is triethyleneglycol divinylether, and the addition of crosslinking agent is polymerization prepared by step a The 5~10% of amount of substance.
The invention also discloses the dielectric film containing amphion full solid state polymer prepared by methods described, its feature It is:The described conductivity at room temperature containing amphion full solid state polymer electrolyte film is 10-4S·cm-1More than, The room temperature electrochemical window is stable in more than 5V.
The invention also discloses the answering in lithium ion battery containing amphion full solid state polymer electrolyte film With.
The present invention grafts to PEO on the side chain of PHMS, to reduce glass transition temperature, so as to reduce solid polymer The degree of crystallinity of electrolyte, as the electric action of PEO simply occurs in noncrystalline domain, therefore reduction degree of crystallinity can improve conductance Rate, simultaneously because PHMS main chains are soft, motility is strong, can strengthen the sub-chain motion ability of PEO, play and further improve The effect of electrical conductivity.In PHMS side chain graft amphions, can play a part of further to improve electrical conductivity, reason is both sexes Ion (sulfobetaines) can promote electron delocalization, at the same sulfonic acid group easily by electrophilic group attack, it is easier to it is low The Li of cloud density+Generation interacts, and plays promotion lithium salts dissociation, forms new lithium ion mobility passage, reach into one Step improves the effect of electrical conductivity;On the other hand, due to introduce amphion, increased the interface stability of electrolyte with it is compatible Property, it is improved polymer electrolyte electrochemical window.
Compared with prior art, the invention has the advantages that:1st, reduce the vitrifying of polymer dielectric Transition temperature, so as to reduce degree of crystallinity;2nd, the electrolyte leakage and the safety decomposed that can solve liquid electrolyte presence is asked Topic;3rd, room-temperature conductivity reaches 3.39 × 10-4S·cm-1, decomposition voltage basically reaches commercially use demand more than 5V;4、 Arbitrary shape can be processed into, different cell shapes demands are met.The present invention can make full solid state polymer electrolyte in lithium ion It is more widely used in battery.
