2SRS
Say on the just general meaning that the electroactive composition of solid-state organic sulfur electrode can (RSy) when charging
nExpression, wherein Y is a numeral of 2 to 6; N is greater than 2, with more suitable greater than 20; R is one or more different aliphatic series or the aromatics part with 1 to 20 carbon atom, and when R comprised one or more aromatic rings, R may comprise one or more oxygen, phosphorus, silicon, sulphur or nitrogen heteroatom; When R comprised an aliphatic chain, R may comprise the chain association therewith of one or more oxygen, phosphorus, silicon, sulphur, nitrogen or fluorine atom, and aliphatic series may be straight chain or branch key, saturated shape or unsaturation shape in this chain.Aliphatic chain or aromatic ring can have substituting group separately.In addition, the characteristics of above-mentioned organic sulfur positive electrode have a large amount of sulphur-sulfide linkages during for charged state, and when battery discharge status, these keys just break and form the organic metal salt that has metal ion in battery.
The charge/discharge process of this positive electrode can be considered a kind of reversible redox polymerization (or under the monomer RSSR compound situation, then being redox two polymerizations/split branch).The example of two dimensions (ladder polymer) electrode can be used polymine disulphide.
Be illustrated as follows:
Though these polymerization electrode materials can transport alkaline metal ions, but must or preferably comprise a suitable polyeletrolyte as a rule, polyethylene oxide for example is so that transport ion rapidly, as the situation of the electrode that embeds type in electrode.In addition, because the organic sulfur electrode is non-conductive, be sought after in composite electrode dispenser a small amount of (be generally 7% weight) carbon ink or equal with it conductor particulate.Material in the polymerization positive electrode, with regard to weight, active organic sulfur is about 30% to 80%, and polyeletrolyte is about about 20% to 70%, and the conductor particulate is about about 1% to 20%.
Desirable mixture can be made with laxative remedy: (SRS)
nPolymer, polyethylene oxide, hydrocarbon black powder dissolving or be sprinkling upon acetonitrile (CH
3CN) make the film (being about 10 to 200 microns) of solvent evaporation in subsequently to cause one deck solid composite electrode.Preferred situation is that positive electrode is one and comprises the organic sulfur redox polymers, the positive electrode of polyethylene oxide and carbon black.
Under the situation of charging fully, the organic sulfur positive electrode has general structural formula (SRS)
n, its main feature is: constitute sulphur-sulfide linkage under alkalinous metal sulfo-salt oxidation situation.Preferred electrode is a kind of polymerization disulphide, but it is believed that at United States Patent (USP) 4,833, and the monomer disulphide of describing in No. 048 (RSSR) also can work in solid state battery.Under abundant discharge scenario, the organic sulfur electrode comprises many sulfo-s and/or two sulfo-anion, and (SRS-), they are scattered in the polyeletrolyte matrix.Certainly, last discharging product is decided by in the polymeric chain R types of radicals and the abundant dimension of the polymerization positive electrode of oxidation.
The performance that another advantage of the present invention is a solid state electrode is reversible to various metals.The advantage of lithium is that equivalent weight and relative weight are minimum, but price is more expensive than sodium.In addition, desirable polyether electrolyte such as polyethylene oxide are carried sodium than carrying lithium conductivity height.Therefore the embedded type battery needs lithium as viable material, and the available multiple metal of the negative electrode of electrode of the present invention constitutes.Therefore, (the polyether electrolyte has shown can transport bivalent cation such as Zn for alkalinous metal alkaline-earth metal or transition metal
++) any all genus within the scope of the invention, particularly comprise the mixture of lithium and/or sodium.
The electrolyte that uses in the battery of the present invention also transports media as metal ion as electrode separation agent usefulness.Therefore, as long as transporting metal ion, all can use any solid material.For example sodium just shows and can use.Yet, the solid electrolyte release agent is preferably used any suitable polyeletrolyte, for example polyether, poly-imines, many sulfo-s ether, polyphosphazene (polyphosphazenes), the material of polymeric blends and the like wherein adds suitable electrolyte salt.
Figure one is a battery critical piece profile constructed in accordance.
Figure two compares with the data of a diagrammatic representation device operational circumstances of the present invention and with the data of prior art same device.
The type of metal sulphur shown in the figure one battery comprises a current collector (11) near negative electrode (12), and the current collector (13) near positive electrode (14) is clipped in the electrolyte (15) between negative electrode (12) and the positive electrode (14).Typical battery situation is: all these parts all are closed within a suitable plastic (or similar material) the shell (not shown), have only current collector to stretch out outside the shell.Like this, just reactive metal in negative electrode such as sodium or lithium are protected, other parts of battery are protected too.
Technology according to needed battery of known assembling and battery component can be made suitable battery structure; And any known topography all can adopt the present invention to make, and mainly makes what purposes according to battery component and decides CONSTRUCTED SPECIFICATION.But should be familiar with each battery component and when ambient temperature is operated, all should be in real solid state.
With regard to figure one, current collector (11,13) is the conductive metal sheet of stainless steel and so on again, remains unchanged substantially under battery discharge and charge condition, and is the positive pole and the negative pole making current of battery.Negative electrode (12) is the alkalinous metal of lithium or sodium and so on preferably, and sodium is better than lithium.Organic sulfur negative electrode or positive electrode (14) set off as described above like that on current collector (13), and whole assembly abuts against together, and electrolyte is clipped between two electrodes as shown in the figure.
The thickness of each parts of battery has all strengthened so that diagram shows among the figure, and these component standards situations all are relatively thinner thin slices in fact.For example, the thickness of typical lithium or sodium solid anodes (12) is about the 10-50 micron, and the thickness of typical solid synthesized polymer negative electrode (14) is about the 50-100 micron, and the thickness of typical PEO electrolyte 15 is about the 10-100 micron.
Desirable electrolyte is a for example polyethylene oxide of polyalkylene oxides, wherein adds for example LiN(CF of plasticising electrolytic salt
3SO
2)
2The effectiveness of plasticising electrolytic salt is to keep polyether to be in amorphous (conduction) state when low temperature, thereby battery is worked at low temperatures.
According to the present invention, organosulfur compound constitutes the positive electrode of novelty of the present invention, be characterized in: the organic sulfur material has at least a sulphur atom and an organic moiety to form first key, and another sulphur atom also is combined into second key with an organic moiety when material is in charged state.When compound was in discharge condition, sulphur-sulfide linkage was broken, and metal ion is sodium for example, just and each organic anion that generates thus form salt.
Therefore positive electrode material comprises a kind of organic sulfur material with basic or backbone formula R-S-, under charge condition, sulphur atom (or a plurality of atom, describe in detail below) form one-S-S-key with the sulphur atom of another radicals R-S-, constitute R-S-S-R, during discharge, the S-S key breaks, and each R-S-base all constitutes salt (R-S-Na) with a metal (as sodium) ion.
The R base (later on again explain) of representing organic moiety not only as above say with the sulphur atom combination, also may be combined into R=S to sulphur atom in two key modes.The R base also may be an above sulphur atom with the combination of singly-bound mode, and this just might carry out polymerization, for example-and the situation of S-R-S-.When the R base have three or three above sulphur atoms with such singly-bound mode in conjunction with the time also branch's situation may appear.
Therefore, the general formula of organic sulfur material when charging with the new-type positive electrode of the present invention can be write as (R(S)
Y)
n, wherein Y is a number of 2 to 6, and n is greater than 20, and R is one or more identical or different aliphatic series or aromatics organic moiety, has the 1-20 carbon atom.When having one or more aromatic rings, R may comprise one or more oxygen, sulphur, phosphorus, silicon or nitrogen heteroatom; May comprise oxygen, phosphorus, silicon, sulphur, nitrogen or fluorine atom that one or more and this key associates when R has an aliphatic chain, wherein aliphatic series can be straight chain or branch chain, and saturated or unsaturation wherein has substituting group on aliphatic chain or the aromatic ring.
As general formula (R(S)
y)
nIn n greater than 2 o'clock, at least some organic sulfur positive electrode materials have the organic moiety that contains an above sulphur atom, are attached to the sulphur atom of same organic moiety and can form sulphur-sulfide linkage with the sulphur that is attached to another organic moiety.Like this under its charge condition, just a polymer-like material can form, the length of polymer depends on impurity or chain stopper such as monosulfide organic moiety (for example CH
3-CH
2-S-Na), they stop polymerization.Such polymer for example, may constitute the linear aliphatic chain that respectively there is such sulphur atom at two ends as-S-CH
2CH
2-S-is so that form dimer, oligomer like-S-CH
2-CH
2-S-S-CH
2-CH
2-S-S-CH
2-CH
2-S-meets general formula (R(S)
2)
3
Equally, organosulfur compound may have the branch chain polysulfide material that contains two above sulphur, can form sulphur-sulfide linkage with the sulphur atom on other organic sulfur materials that are close to.For example when each R base comprised three sulphur atoms that can constitute sulphur-sulfide linkage, general formula can be write as (R(S)
3)
n
Therefore, it is 1 to 6 that the y in general formula decides its value, and this is to have recognized two kinds of possibilities, and one may be to have two key sulphur on the R base, and another kind may be that an above sulphur atom on it can be formed sulphur-sulfide linkage with the same sulphur atom on other molecules.N value in general formula is preferably greater than 20, but also decided one simultaneously and comprised 2 to 20 scope, this is to recognize that polymerization might be in the lower stage, for example forms ring, also is beneficial to because solid state battery has the organosulfur compound of not polymerization simultaneously.N value no maximum is because the character of employed organosulfur compound has limited the degree of polymerization under charge condition.

The working temperature of solid state battery is between-40 to 145 ℃, and the upper limit is exceeded with one of two electrodes or electrolytical fusing point.Desirable temperature is between the ambient temperature to 100 ℃.The sodium negative electrode is limited to 98 ℃ of following temperature, but sodium alloy electrode such as Na
4Pb can substantially exceed 100 ℃ to be used in solid-state.
Employing solid polymer electrolyte and solid oxide reductive polymerization negative electrode just might be made all-solid-state battery, and do not produce and use difficulty solid-state firmly or that liquid electrolyte is relevant.The viscosity of solid-state polymerization electrolyte and solid oxide reductive polymerization negative electrode and elasticity have prevented the forfeiture that electrically contacts between battery cycle period solid electrolyte and electrode or have seriously weakened.In addition, the present invention improves prior art, promptly replaces some mordant liquid material with safe solid state component.This change is very easily made and is packed with regard to making battery available height automation process constructed in accordance, and battery does not have corrosiveness to container material yet.
