Description
Technical field
What the present invention relates to is dielectric of a kind of technical field of lithium batteries and preparation method thereof, specifically is a kind of polyphosphazene urethane single ion solid electrolyte preparation method.
Background technology
The portable type electronic products such as making notebook computer, mobile phone, digital camera that develops rapidly of microelectric technique has obtained popularizing widely.Supporting power supply as portable type electronic product; Lithium rechargeable battery because have that specific energy is big, operating voltage is high, temperature limit is wide, self-discharge rate is low, have extended cycle life, pollution-free, special advantages such as security performance is good, become one of optimal environmental protection power supply of 21st century.
According to the electrolytical difference that is adopted, lithium rechargeable battery can be divided into liquid lithium ionic cell and polymer Li-ion battery.Polymer Li-ion battery is except that the advantage with liquid lithium ionic cell; Owing to adopted immobilising polymer dielectric; Also has the better advantage of security performance; And can process the ultra-thin battery of arbitrary shape and size, thereby be more suitable for power supply as miniature electrical equipment, range of application is also wider.Since polymer Li-ion battery in 1999 was realized industrialization, part substituted liquid lithium ionic cell, and was expected to replace fully in future liquid lithium ionic cell.
Polymer dielectric is divided into double ion conductivity type electrolyte and single ionic conduction type electrolyte.Usually the polymer dielectric that adopts all is a double ion conductivity type electrolyte.Through knowing to the research of polyethers in the polymer dielectric-electrolytic salt complex compound electrical conduction mechanism; Anion and cation will be distinguished anode and cathode motion under effect of electric field; Form the carrier concentration gradient in inside; Produce and external electric field antipole electrochemical potential, its result will cause the ionic conductivity of material to be moved in time and decay rapidly, significantly reduce the energy efficiency of battery.The effective measures that solve polymer dielectric internal polarization problem are to adopt single ionic conduction type polymer dielectric.The electrolytical design principle of this base polymer is for to be fixed on anion on the polymer segment through covalent bond; Suppress anionic motion by relatively large volume of polymer and the mutual winding between strand, thereby obtain the single ion conductor that single cation is a charge carrier.So because have only a kind of ion can serve as the electrolytical conductivity of the single Ionomer of charge carrier generally than low 1~2 one magnitude of conventional polymer double ion conductor electrolyte; But single Ionomer electrolyte dc conductivity is moved in time hardly and changes, and this is very favourable to improving battery performance.
Thermoplastic polyurethane (TPU) has typical two phase structure, and its polyether segment can be used as soft section and alkali metal salt generation solvation, promotes the disassociation and the transmission of charged ion, guarantees that solid electrolyte has certain conductivity; Hard section of the molecule that is formed by carbamate isopolarity group can be used as the physical crosslinking point, makes polyurethane have good mechanical performance and film forming.Therefore, select for use polyurethane, can take into account the electric property and the mechanical property of copolymer solid electrolyte, can obtain having the new polyurethane polymer dielectric of excellent mechanical property and ionic conducting property through certain MOLECULE DESIGN as matrix.
Poly phosphazene (PDCP) is alternately to arrange with the phosphorus nitrogen-atoms on one type of main chain, and side chain is the novel organic inorganic hybridization macromolecule of different substituents.The main chain of poly phosphazene material has the replacement diversity of superior compliance and side group; The backbone that the main chain of poly phosphazene is made up of with the Dan Shuanjian that replaces the P that replaces, N atom; Owing to exist the pi-conjugated stabilization of d π-p between the P-N key on the main chain, so the chemical stability of main chain is higher.And because the Dan Shuanjian that replaces on the main chain fails to form the long-range conjugated system; Two keys do not cause obstacle to the rotation of P-N key; So compare with the main chain of organic polymer, the poly phosphazene high polymer main chain has higher torsional compliance, great majority are the low temperature elasticity body.Behind the side chain (being mostly the ether chain) that these architectural characteristics have determined the poly phosphazene macromolecule to connect to contain the solvation group, will be the macromolecule main body of one type of good solid electrolyte.But the poly phosphazene solid electrolyte exists poor dimensional stability, and molecular weight is not high, many problems such as poor mechanical property.How to utilize the excellent molecule designability of poly phosphazene polymer, let two kinds of mutual modifications of important polymer of poly phosphazene and polyurethane,, prepare a kind of new type of polymer electrolyte, cause polymer science man's attention already in conjunction with both advantages.
Literature search through to prior art is found; Chen Jianjun; Wang Lei, Tang Xiaozhen etc. rolled up 71~75 pages of the 1st phases in 2002 the 36th at " Shanghai Communications University's journal " and have delivered " polyurethane/hyperbranched poly ether sulfate list ion-type solid electrolyte ", mentioned in the literary composition; Polyethylene glycol oxide polyurethane (PEU) and hyperbranched poly ether sulfate (SHPG-Na) blend have been made single Ionomer solid electrolyte; Means such as utilization complex impedance spectra etc. characterize it, and the result shows, cation in this compound system and ether oxygen atom generation complexing also strengthen with the increase of salinity; Temperature is bigger to the influence of the complexing between the ehter bond in the high salt concentration system and carbonyl and cation, and less to the influence of low salt concn system; High ionic conductivity is 3.1 * 10 under the room temperature (25 ℃)
-6S cm
-1, moderate temperature (60 ℃) is issued to 10
-5The order of magnitude.But its preparation method is complicated, and step is various, changes proportioning and salinity difficulty, and therefore, a kind of synthetic convenient with modification, the exploitation of single ionic electrolytes that conductivity is high becomes problem demanding prompt solution.
