Abstract
The utility model provides a high-power natrium sulfur power battery improved from material to technology, which is in single combination and appears a rectangular object. The power battery comprises a reaction bottle for the anode active matter sulfur in the casing, a conductive ceramics electrolyte, a reaction bottle for cathode active matter natrium, and two electrode bars which extend out of the casing and form a connection post between the anode and the cathode. The major difference between the high-power natrium sulfur power battery of the utility model and the original natrium sulfur battery is that after improvement, the service life is prolonged by over one time; as the energy is enhanced, the application range is consequently more extensive than the original natrium sulfur battery.
Description
Technical field
The utility model relates to a kind of new electric energy device, is the battery that a kind of charging capable of circulation is used, under vacuum condition, be made, and especially high-power sodium sulphur electrokinetic cell, it is different from former " sodium-sulphur battery ".This battery can be used as the power source of train, boats and ships, warship, submarine, replaces the dependence to petroleum resources, and does not discharge any material, also can power as city illumination with power networking, especially compatibly descends mining industry and replaces automobile engine.
Background technology
At present, known in industry sodium-sulphur battery energy is big, volume is little, long service life, and the charging interval is short, and its reason is that its active material is not plumbous (Pb) and brown lead oxide (PbO
2), but chemical substance sodium metal (Na) and sulphur (S), electrolyte neither aqueous sulfuric acids, but many sodium aluminates conductivity ceramics, molecular formula is Na
2O-Al
2O
3, the special alundum (Al (β " Al of shellfish
2O
3) ceramic electrolyte separates sodium and sulphur, constitutes the positive and negative electrode of battery, forms the electrochemistry loop.Battery in use also needs charging, but not exclusively depends on electric power storage, but by the electron transfer regenerated energy, and therefore the disposable charging interval need only dozens of minutes, but nearly 20,000 times of trickle charge, just in the useful life more than 10 years.The theoretical energy of battery after thermal response is 780 watt-hour kilograms, and this is more than ten times of lead-acid battery under equal capacity, but there is the defective of following three aspects in former " sodium-sulphur battery ", also is fatal.
(1) during battery discharge, the sodium ion in the negative pole storehouse pours out, and the liquid level of sodium is descended, and is in no liquid status more than the liquid level fully, makes that electrolytical ionic radius is efficient all to quit work, and the battery gross energy is descended with sodium liquid weaken.
(2) degeneration in advance of the sticking electrode bar of graphitic carbon: the active material of battery---sulphur is insulator, when sulphur atom immerses the graphite micropore, has increased the resistance of electrode bar, its conducting function is degenerated, and battery is scrapped in advance.
(3) electrolyte---the calcium (Ca) in the conductivity ceramics, and little pore also is insulator, and when the thermal response temperature of battery rises to certain value, calcium dissociates out and hinders electrolytical ionic radius, sodium ion can't penetrate ceramic wall, and the energy content of battery descends rapidly and scraps.
Summary of the invention
The utility model provides a kind of high-power sodium sulphur electrokinetic cell, and the technical scheme that technical problem adopted that it solves above-mentioned three aspects is:
A kind of high-power sodium sulphur electrokinetic cell, wherein, described electrokinetic cell is single combined, and the outward appearance blocks that is rectangle is included in the shell reaction bulb and two electrode bars for the reaction bulb of positive active material sulphur, conductivity ceramics electrolyte, negative electrode active material sodium; Two electrode bars stretch out outside the shell, constitute the battery plus-negative plate binding post.
According to the utility model, wherein, the single combined outward appearance blocks that is rectangle.
According to the utility model, wherein, described shell is synthetic by the high molecular polymer carbon fibre.
According to the utility model, wherein, described battery positive electrode active material reaction of Salmon-Saxl bottle is the cylinder doleiform, and the upper end is provided with the sodium polysulfide surge bunker, and material is special stainless steel Fe-Cr
72Mo
2Ti.
According to the utility model, wherein, described cell electrolyte is the cylinder doleiform, and material is many sodium aluminates, molecular formula Na-β " Al2O3.
According to the utility model, wherein, described negative electrode active material reaction bulb, the member of newly establishing in former sodium-sulphur battery electrolyte ceramics inside is the Cylinder doleiform, divides into spray orifice, material is special stainless steel Fe-Cr72Mo2Ti.
According to the utility model, wherein, described two electrode bar materials are the extraordinary zirconium metallic Z r that adopt the nuclear reactor rod.
As depicted in figs. 1 and 2, the utility model can provide a kind of high-power sodium sulphur electrokinetic cell through to the replacing of material and the process modification of three-step approach, and can be enhanced about more than once than originally its useful life, near 20,000 trickle charge, and need not keep in repair throughout one's life.Because its power no longer weakens, and just can be used as the driving source of train, boats and ships, warship, submarine, and use as city illumination with power networking, with high-power bulk, small-power monomer composite type can be used for the urban transportation vehicle, and to replace its engine, no longer relying on petroleum resources is fuel.
Description of drawings
Fig. 1 is the utility model battery cell vertical section overall structure figure;
Fig. 2 is the utility model general structure schematic diagram.
Description of reference numerals:
The reaction bulb 2 of battery sulphur, conductivity ceramics electrolyte 3, sodium reaction bulb 4, electrode bar 5.
Embodiment
As shown in Figure 1, icon 4 is newly-increased in former " sodium-sulphur battery " sodium reaction bulbs, it is characterized in that the cylinder doleiform, divides into the radiation spray orifice, and sodium liquid is subjected to the factor of sodium air pressure in the bottle, and sodium liquid soaks casual ceramic wall by ejection in the base apertures.Sodium liquid in the bottle promptly is to descend more than 85%, and ceramic wall remains the thick sodium liquid that reaches several millimeters, and it has solved the phenomenon that weakens because of sodium liquid decline energy.
As shown in Figure 1, icon 5 is electrode bars of battery, has now used zirconium metal (Zr) instead, can not degenerate with the lifelong life-span of battery.
As shown in Figure 1, icon 3 is the conductivity ceramics electrolyte, and cylindric for the bottle type, material is the special alundum (Al (β " AL of shellfish
2O
3), its manufacture craft is: the processing back particle mean size of learning from else's experience is the β " AL of 0.4 μ m
2O
3Powder, with the absolute ethyl alcohol be medium through ball milling, make wine mud, spray-dried granulation, pre-burning under 1250 ℃ of conditions, this is the first step.Making powder again in mould, be shaped with static pressure under the 195-200mPa pressure and put into saggar, go into stove through sealing outward, through 1450-1590 ℃ of calcining, was second step.Treat that furnace temperature is self cooling, take out finished parts, take out system light after 24 hours with 350 ℃ of tempering, this was the 3rd step.This pre-burning three-step synthesis method claims temporarily " three-step approach " can eliminate the invalid element of little pore and calcium in the battery conductive pottery.
The utility model provides a kind of high-power sodium sulphur electrokinetic cell, and can be enhanced about more than once than originally its useful life, near 20,000 trickle charge, and need not keep in repair throughout one's life.Because its power no longer weakens, and just can be used as the driving source of train, boats and ships, warship, submarine, and use as city illumination with power networking, with high-power bulk, small-power monomer composite type can be used for the urban transportation vehicle, and to replace its engine, no longer relying on petroleum resources is fuel.
