Description
Technical field
The relevant electrical technology of the present invention refers to a kind ofly convert chemical energy to electric energy especially, and replys the method and apparatus of storage battery power supply ability.
Background technology
Energy resource supply problem now mainly comes from developed country and carries out middle country and since non-renewable resources have restriction in the use (for example: oil, natural gas ... etc.), the progress of country causes the problem of energy resource supply more and more serious.
And, limited the use of the renewable energy resources such as wind power generation, solar energy, tidal power generation because of global economic development and specific topoclimate.In addition, the research renewable energy resources need the fund of the more than one hundred million units of cost to implementation from research, demonstration project.When twentieth century, majority tend to build thermoelectric power, and this part has solved the problem that liquid hydrocarbon consumes.The possibility of building thermoelectric power at the twentieth century end and initial stage 21st century decline gradually.Scientist believes that global warming is because carbon dioxide destroys atmosphere, causes greenhouse effect; And the reason that causes carbon dioxide hurriedly to increase is the gas that thermoelectric the subject of knowledge and the object of knowledge gives off.Majority state adopts the agreement in the Kyoto Protocol, thereby has influenced the development of thermoelectric power.
Because growth, the development of automobile industry, the manufacturing industry motorized of commercial power particularly provide the human required shortage of using, self-sustaining demands for energy is more and more high, and on different economic industries and industry, traditional storage battery constantly is used.High-effect rechargeable battery pack contains plumbic acid battery, nickel-cadmium cell, nickel metal oxygen cell, nickel-zinc cell, lithium battery, and it is used at notebook, e-dictionary, video camera, mobile phone widely ... wait small-sized electronic product.
Storage battery has solved the demand of electric energy, also improves the people's lives happiness, but when battery life is used up, but causes environmental problem.It is reported that when storage battery was destroyed, its constituent can cause environmental pollution, this factor impels people constantly to study the method that improves the storage battery access times.
Show have two kinds of methods to remove to increase the access times of storage battery according to data.These methods can generally be divided into mechanical type method and electric method.
The electric current of the self-sustaining energy such as storage battery and chemical cell is to produce through chemical action.Chemical cell after the charging can make the chemical synthesis deposits yields impurity in the battery, uses and galvanic influence through continuous charging, and electrode material can constantly be consumed, and causes its quality and descends gradually.In other words, these chemical elements can't restore.Many different types of self-sustaining energy are arranged, and its mode of operation is based on the reversibility pricinple of chemical action.Storage battery is a well known chemical energy power supply.Make the employed brown lead oxide of storage battery (PbO2) and lose plumbous (Pb) quite high in the chemical stability of sulfuric acid electrode.In lead-acid battery, its effective material use factor (active material utilization factor) is about 0.4, that is, in the middle of the running of storage battery, have only effective material of 40% to produce chemical action with battery lead plate; Having 60% chemical substance not have approximately cuts any ice.In other words, this chemical substance of 60% does not produce any variation, has only 40% to participate in main chemical change, and this chemical substance of 40% can be restored.
In known technology, the method for many recovery storage batterys is to adopt mechanical solution.Go to reply the part and the outfit of enclosed type accumulators through equipment and outfit, its step is included between the both positive and negative polarity the ionic conductance decrement, opens battery case and reclaim the part of battery.With the ionic conductance decrement time, be to use the security ventilating pipeline to remove to remove electrolyte solution, and battery is cooled to cold spot, or reduce to the glass transition temperature, make it to be frozen into polymer (with reference to SU 1034559 A, 26.04.1995; SU 877660 A, 30.01.1981; RU 94025555 A1,20.05.1996; DE 4424825 A1,18.01.1986; RU2201018 C2,05.03.1997; USSR certificate number 112833; Si Enni: use, store, and the maintenance storage battery, 1991, c.94).
Moreover in the method for known answer lead acid accumulator, battery is distinguished into the semi-simple position of both positive and negative polarity; Collect these invalid positive/negative plates and change a new battery lead plate, again with this storage battery through reconfiguring and (the Si Enni: use, store that charges; And the maintenance storage battery, 1991, c.94).In order to restore these batteries, must use a new battery lead plate, its expense costliness very.And the method can't be used settled lead, and causes environmental pollution.
Another mechanical type solution of restoring storage battery is to reclaim lead acid accumulator, when service life of lead accumulator is used up, is divided into the semi-simple position of both positive and negative polarity; The positive plate that damages is resolved into powder, and mixed electrolyte liquid, bulk object formed; It is positioned on the netted glove compression and air-dry.Through above-mentioned steps, storage battery will be reconfigured, and rechargeable (USSR certificate number 112833).
In a normal spendable storage battery of function, sulfuric acid can corrode pole plate, can cause the positive/negative plate of a part to peel off, and makes to cause deposition.Yet all elements in the battery can't disintegration be totally fully because of electrochemical action.Because pole plate can corrode, it is very difficult using pure pole plate.In addition, convert the mixed dough of electrolyte solution to chemically-reactive substance, this dough must be passed through the formation program could produce chemism.
Below the recovery lead acid accumulator method of narration can be eliminated above-mentioned shortcoming.The battery that will excessively use earlier is divided into the semi-simple position of both positive and negative polarity, and the positive plate that damages is resolved into powder, and mixed electrolyte liquid, forms bulk object, it is positioned on the net compression and air-dry.Through above-mentioned steps, storage battery will be reconfigured, and rechargeable.Next positive plate particle after the damage can need mixed-powder and electrolyte solution between 0.02～0.04 μ m, and its ratio is 1: 0.13.The method also comprises and removes the sulfation degree from negative plate to surpass 20% erosion plumbous; And the bulk object that obtains is placed on the net; Celsius temperature at 20～30 atmospheric pressure, 30～100 degree was dried 24 hours; The positive plate that makes is arranged in the anodal semi-simple position, and the sulfation degree that makes is arranged in the semi-simple position of negative pole less than 20% negative plate.Before charging, the semi-simple position of positive/negative plate device in storage battery, is added distilled water and is placed in the accumulator box; Direct current is essential to be situated between at 0.03～0.05A; This moment, brown lead oxide can form on positive plate, and erosion lead will become activated state, can charge (RU 2076403) on negative plate.
Said method can be eliminated the shortcoming of the method for USSR certificate number 112833.Yet these methods need be used very complicated professional technique equipment, but not general Automobile Service Factory can carry out.
From the angle of technical program and required auxiliary equipment, the method for replying lead-acid battery includes: the composition of dismounting battery; Reclaim unnecessary negative electrode quality, but do not remove from screen; Use canvas that electrode is gently pressed, it is positioned over to cause after the immersion in the distilled water with screen dries, after its drying, the negative electrode quality will reduce; Be placed in 450～500 degree high temperature Celsius up to presenting yellow powder; Add distilled water and be mixed to powder, and mix sulphur acid concentration (1.40g/cm3) is to bulk object; Bulk object is smeared to battery lead plate; With twice of glue rod roll extrusion; Drying 20～25 seconds or natural air drying are 4～6 minutes under 120 ℃ temperature, and then Jiao Gunbao the gauze roll extrusion once, and the battery lead plate of manufacturing was consolidated 16～18 hours in the roasting of the humidity below 45～50 ℃ and 95%; Under the temperature identical with last step, humidity is reduced to solid 20 hours of 75% roasting; 68～70 ℃ of oven dry, air humidity was placed 12～14 hours below 20%; Above-mentioned storage battery part is formed (make up positive and negative semi-simple battery lead plate, shift the battery that the product cleaning has been used up, boiled then 5 minutes), with its charging through the electrochemistry logistics.(replying the lead acid accumulator that damages with technology and instrument: technological sciences thesis for the doctorate, Ryazan, 2000, page or leaf 74-77,89).
When analyzing the technical scheme of mechanical type recovery lead acid accumulator method; Confirmable is that each step all is technical program; This must spend many manpowers and complicated high technology equipment is reached, and the solution that these shortcomings impel industry to go for other is come more efficient answer lead acid accumulator.As previously mentioned, wherein a kind of mode is referred to as the electric method.
The method that many use electric means recovery storage batterys are arranged in the known technology is (with reference to DD 38201 A; SU 909754 A, 1982; SU 911677 A, 1982; SU 1713015 A1,1992; Bolotskiy V.S.Chemical current sources, 1981, c.238-239; US 4494062 A, 1985; US 4568869A, 1986; Russian Industry, No.9,1999, c.18-20; SU 1702873 A3,1991; RU9408854 A1,1996; SU 851569 A, 1981; US 5631542 A, 1997; US 5614805 A, 1997; RU 2153741 C2,2000; RU 2025022 C1,1994; DE 3811371 A1,1990; RU 2226019 C1,2004; RU 2218696 C1,2003; SU 1534634 A1,1990; WO91/07000,1991; US 5541966 A, 1996; EP 0444617,1991; EP 1184928 A1,2002; WO OO/62397 A1,2000; JP 2001-118611 A, 2001; JP 2006-032065 A, 2006; JP 2000-323188 A, 2000).
Relatively after electric method and the mechanical type method, can find that manpower that the electric method uses is less and handling procedure is simpler, required equipment and the equipment of realization electric method can be had in general laboratory.
The method of the voltage source of the answer battery that another kind is known is to use the wave amplitude and the length of the periodic voltage pulse that has been set; Its wave amplitude is between 2～200Hz; Length is then between 10-3～2 * 10-3, based on the internal resistance of voltage source, will reply electric current and be arranged on 5 * 10-2～15 ampere.The related machinery equipment of the method comprise signal generator service time dc voltage source regularly; According to time signal generator setting-up time length and guarantee that potential pulse has fixedly wave amplitude; And rise in the short time; Its length is fixed, and potential pulse is linked to voltage source limit (RU 2153741 C, 1994).
The method of the recovery cadmium-nickel storage cell that another kind is known includes: before discharge, measure the voltage of battery at first earlier, and the magnitude of current in the recording cell, do comparison with the numerical value that presets.Do not have at battery under the situation of short-circuit component, need carry out a regeneration cycle at least and comprise the action of carrying out discharge and charging.Discharge and charging the time all use alternating current to carry out, and this alternating current has fixing amplitude, frequency to be 20KHz～80Hz and to be asymmetric broached-tooth design with respect to 0V.When charge mode, the ratio of averages of charging current is (20-4) with the average of discharging current ratio: 1; When the discharging current pattern, it is than being 1: (4-20), its pulse wave amplitude surpasses four to five times of the averages of charging current.In battery, have under the situation of short-circuit component, carry out before the regeneration cycle, the preliminary earlier normal current charging of using.Then, with storage battery be connected to capacitance be 10,000 μ F and voltage be charged to 25～60V capacitor for several times, with than the horizontal current of low 4～10 times of nominal numerical value with battery charge to nominal numerical value.With the voltage of 0～0.5V with battery charge.According to technical specification with battery charge to peak.Continuous reignition regeneration cycle.
The above is the program that must carry out, and required equipment is following: supply unit, and will charge and electric discharge device is received on the battery, charge and electric discharge device is the driving generator that is connected on the storage battery.Also need a control and an indicating device, use control circuit will drive generator and be connected to control and indicating device.The output that drives generator is connected to the input of current generator, and the output of current generator is connected to storage battery and control and indication.Wherein the additional capacitors device also can be provided with switch, guaranteeing and can voltage be converted to 60V from 25V, and is connected to storage battery (RU 2185009 C, 2000).
Use the electric technology to reply storage battery and reduce many shortcomings, the answer program of particularly simplifying than using the mechanical type method.But the electric energy that uses electrical technology to reclaim storage battery also can't be compared with the electric energy of new battery, so the number of times that recharge uses is quite limited.
Known method be through ambipolar pulse current to charge in batteries, the method receives the influence (order formation be the direct current mode through limit capacity) of monopolar current pulse break sequence, the discharge current pulse amplitude can embed it and was interrupted the space this moment.When battery is recovered, use to handle electric wave and can reduce distributing of heat, be feasible program preferably.When fill order's electrode current electric wave, be interrupted and electric wave between can be constantly alternately, at this moment, stationary electrode changes into long speed and eases up gradually, because discharge electric wave amplitude can cause depolarising, so the relative minimizing (SU 1534634 A1) of static polarization.Technology operation shows, removes the battery that reclaims with above-mentioned method, and battery component begins to react, and forms crystalline solid gradually.At the program initial stage, because the contact of the positive pole of battery and electrolyte solution reduces, battery will lose electric energy gradually and can increase internal resistance; In program latter stage, the crystalline solid in the growth will destroy distinguishes the both positive and negative polarity electroplax.In the program of replying, storage battery can show high-energy, but because its self discharge electric current is too high, so be not suitable for further going utilizing.
Above-mentioned rechargeable battery can overcome with another kind of method with the shortcoming of restoring battery; Its step is that the input charging current is charged it in battery; And use charging pulse with the mode of pulse series connection with mechanical shock, its frequency is between 3～30KHz (RU 2226019 C, 2002).
In fact, by the effect of discharge pulse, can dwindle the internal resistance when having reduced charge in batteries at the volume of the big type crystal structure on storage battery surface.Simultaneously, this also can cause anodal active matter to speed up because of what irreversible decay was corroded, makes that the unicity of active matter and mechanical strength are ineffective.
