Description

A kind of dielectric film containing amphoteric ion full solid state polymer and preparation method thereof and Purposes
Technical field
The present invention relates to a kind of dielectric film and its preparation method and application containing amphoteric ion full solid state polymer.
Background technology
With the development of the social economy, demand of the people to the energy increasingly increases, at the same it is dirty in global warming, air It contaminates that the problems such as serious is especially prominent, drastically influences 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 the Main way of Future New Energy Source development is become, and lithium ion battery is not only at present It is widely used in the mobile electrons such as smart mobile phone, laptop, stereo set, game machine, digital camera, palm PC to set It is standby, also it is increasingly used in electric vehicle, unmanned plane, earth orbital flight device, airline carriers of passengers etc..
Current market sales of lithium ion battery mainly uses carbonates liquid electrolyte systems, although having higher Ionic conductivity, but organic solvent has and is easy that leakage, flash-point is relatively low, easy firing, the characteristics such as volatile, toxic, in mistake It fills, collide, squeezing etc. in special circumstances, it may occur however that the safety accidents such as leakage, burning, explosion, to the personal property of user Safety causes certain threat, it would therefore be highly desirable to which 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 be satisfied commercially use requirement Want reason.PEO is most common polymer electrolyte at present, however conductivity is relatively low under PEO and lithium salts mixed room temperature, is needed It to be further modified, improve the conductivity of polymer at room temperature.Currently, the main method for improving conductivity has grafting, blending, is total to The methods of poly-, addition inorganic filler.Since PMHS segments are soft, motility is good, and PEO is grafted to PMHS side chains, not only may be used To reduce PEO crystallinity, and the advantage that PMHS sub-chain motions can be utilized good, the electric conductivity of PEO segments is further increased, Amphoteric ion is further introduced into PMHS side chains, can not only form new lithium ion mobility channel, improves conductivity, Er Qieke By improving cell interface performance, to play the role of improving electrochemical stability, therefore prepare electric conductivity and stability is equal The polymer dielectric film for the lithium ion battery applications that can be met the requirements.
Invention content
The purpose of the present invention is to solve existing full solid state polymer electrolyte room-temperature conductivities low, electrochemical window is not High problem.The present invention provides a kind of dielectric film containing amphoteric ion 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 amphoteric ion full solid state polymer electrolyte includes the following steps:
A, it by hydrosilylation, prepares side chain while being grafted PEO and zwitterionic polymethyl hydrogen siloxane, Shown in 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 are dissolved in acetonitrile or acetone solvent, are stirred at room temperature Mix, pour into Teflon mould after mixing, be placed in heat drying in vacuum drying oven, crosslinking film forming, prepare containing Zwitterionic full solid state polymer electrolyte film.
Preferably, the step a is specific as follows:
1) it is sufficiently mixed PMHS and organic solvent to obtain solution A, then mixes DMAA, PEO, catalyst and organic solvent It closes uniformly, obtains solution B, solution A is preheated to 40~60 DEG C, under inert gas atmosphere, solution B is slowly added dropwise into A, drip Add rear mixed liquor the reaction was continued at 40~60 DEG C 2~3h, then raises temperature to 70~90 DEG C of reactions until C=C disappears, reaction terminates Organic solvent is removed, product C is obtained;
2) it is sufficiently mixed product C and organic solvent to obtain solution D, 45~60 DEG C is preheated in inert gas environment, it will 1,3- propyl sultone is added in solution D, is reacted 16~20 hours at 45~60 DEG C, removes organic solvent and obtains product E, product E is formula (1) structure.
Preferably, DMAA and molar ratio≤0.04 PEO in the step 1);Organic solvent described in step 1) is Toluene, step 1) catalyst are chloroplatinic acid, are fed intake as 10~40ppm, and preferably chloroplatinic acid catalyst feeds intake as 20ppm.
Preferably, the organic solvent described in step 2) is tetrahydrofuran;The amount and step of 1,3- propyl sultone is added 1) it is 1 that the DMAA being added in, which meets molar ratio,:1.
Preferably, lithium salts used is bis trifluoromethyl sulfimide lithium, the PEO satisfactions [EO] of lithium salts amount used and addition: [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 amphoteric ion full solid state polymer prepared by the method, features It is:The conductivity at room temperature containing amphoteric ion full solid state polymer electrolyte film is 10-4S·cm-1More than, The room temperature electrochemical window is stablized in 5V or more.
Contain amphoteric ion full solid state polymer electrolyte film answering in lithium ion battery the invention also discloses described With.
The present invention grafts to PEO on the side chain of PMHS, to reduce glass transition temperature, to reduce solid polymer The crystallinity of electrolyte, since the electric action of PEO is only happened at noncrystalline domain, conductance can be improved by reducing crystallinity Rate, simultaneously because PMHS main chains are softer, motility is strong, can reinforce the sub-chain motion ability of PEO, play and further increase The effect of conductivity.In PMHS side chain graft amphoteric ions, can play the role of further increasing conductivity, the reason is that both sexes Ion (sulfobetaines) can promote electron delocalization, while sulfonic acid group is easily by the attack of electrophilic group, it is easier to it is low The Li of cloud density+It interacts, plays and promote lithium salts dissociation, form new lithium ion mobility channel, reach into one Step improves the effect of conductivity;On the other hand, due to introducing amphoteric ion, increase the interface stability of electrolyte with it is compatible Property, so that polymer electrolyte electrochemical window is improved.
Compared with prior art, the invention has the advantages that:1, the vitrifying of polymer dielectric is reduced Transition temperature, to reduce crystallinity;2, electrolyte leakage and the safety decomposed existing for liquid electrolyte can be solved to ask Topic;3, room-temperature conductivity reaches 3.39 × 10-4S·cm-1, decomposition voltage is more than 5V, basically reaches commercially use demand;4, It can be processed into arbitrary shape, meet different cell shapes demands.The present invention can make full solid state polymer electrolyte in lithium ion It is more widely used in battery.
