S30, detects the range of capacity whether described capacity data is in setting
S40, if so, then judges that described lead-acid battery Performance Detection is passed through, otherwise, judge that described lead-acid battery Performance Detection is not passed through.
The most direct performance reaction of lead-acid battery is exactly its capacity, if work as the capacity attenuation of battery 20 percent, can think dead battery; Cell lost efficacy, and not only caused the sharply reduction of integral battery door pool-size, also can make at each monomer charge voltage of electric battery uneven, there is potential safety hazard, therefore, carry out related detection according to capacity data to lead-acid battery, can comparatively comprehensively characterize its performance.
The lead-acid battery method for testing performance that the present embodiment provides, by loading the experimental temperature of setting to described lead-acid battery, within the scope of setting voltage, carries out cycle charge-discharge experiment to described lead-acid battery and experiment disassembled by battery; After several times charge-discharge test is repeated to described lead-acid battery, obtain the capacity data of described lead-acid battery; Detect the range of capacity whether above-mentioned capacity data is in setting again, judge the performance of described lead-acid battery according to the result detected; Wherein, only need obtain the capacity data of lead-acid battery in experimentation, above-mentioned capacity data is analyzed, just can reach the object detecting lead-acid battery performance, consuming time less, the efficiency of lead-acid battery Performance Detection can be improved.
In one embodiment, degree of depth charge-discharge test is done to lead-acid battery, constant temperature 60 DEG C (degree Celsius) can be selected, the lead-acid accumulator of six groups or more 2V-200Ah (ampere hour) of connecting does cycling life test, adopt the method for fast charging and discharging, maximum charging and discharging currents is respectively 50A (ampere), within four hours, namely complete the electric discharge of battery, the charging of complete battery pair within four hours accordingly.Each discharge and recharge to the voltage of single accumulator be 2.25 and 1.7V (float charge voltage of this battery is in 2.22-2.24V, and lead-acid battery monomer voltage 2.25V takes advantage of 6, is exactly 13.5V.Sparking voltage can not take advantage of 6 lower than single lattice 1.7V, namely 10.2V), continuous circulation 30 is removed a battery, is carried out disassembling test after enclosing, after modification of program being become five groups it (11.25 – 8.5), continue test, the like, until all surveyed six Battery packs, the cycle index that can bear of record accumulator, is the life-span.
The electric discharge of valve controlled sealed lead-acid accumulator mainly divides following three stage by stage:
A), battery terminal voltage is down to open-circuit voltage rapidly by floating charge, and now large to dropping to about 2.13V by 2.23V, therefore to voltage process transfer open-circuit voltage to by float charge voltage, and not actual open circuit sparking voltage, so it is fast especially to decline.
B), battery side pressure presses off by open circuit and begins to decline steadily, and normally in situation, battery discharge the genus smooth transition phase during 1.80-2.06V, and battery side pressure declines steadily.
C), when battery reaches final voltage 1.80V, if now continue electric discharge, then discharge rate is accelerated, also belong to the overdischarge process of battery during this simultaneously, if there occurs overdischarge, then must carry out supplementing electricity to battery in time, otherwise inside battery sulfation can be caused, recover original capacity and will bring very large difficulty.
In one embodiment, can also to above-mentioned lead-acid battery, first its new battery is disassembled, measure battery apparent size, observe pattern and inner macrostructure (comprising safety valve, bus-bar, pole, the structure such as pad, barrier film canoe between screen and bus-bar), and take pictures and preserve to compare, especially the quality of primary part observation barrier film, pole plate and surface condition, sample positive and negative electrode cream in passing.
Then obtain original electrolytic solution by presses against diaphragm, step is as follows:
1, first use clean polyfluortetraethylene plate presses against diaphragm, obtain muddy electrolytic solution.
2, filter three times with glass fiber filter again, obtain clarification electrolytic solution, then carry out dependence test.
Then, observation experiment is disassembled to the battery after same batch cycle.Halted state when battery is disassembled is half electricity condition.Although there are some researches show in the higher situation of battery liquid density, namely during Charging state, distribution iron contamination is in the solution more, but consider and can to detect other foreign ions simultaneously, based on this, the halted state of battery is set to half electricity condition after enclosing by circulating battery 30.
Battery after circulation is disassembled, obtains the electrolytic solution after circulation.
When 1, disassembling the battery after circulation, equally the apparent size of battery and inner structure are observed, taken pictures sampling in the obvious position of damage ratio, contrast with original battery, analyze the reason producing infringement.
2, use polyfluortetraethylene plate presses against diaphragm, obtain muddy electrolytic solution.
3, filter three times with glass fiber filter, obtain clarification electrolytic solution, dependence test is carried out to electrolytic solution.
A () utilizes inductively coupled plasma spectrum (ICP) to detect electrolytic solution concentration impurity ion;
B () utilizes the acidity in titrimetry detection electrolytic solution, i.e. pH;
C () utilizes graduated cylinder and electronic balance, detect the proportion of electrolytic solution; Details is as follows, is first cleaned by graduated cylinder and dries, be placed on electronic balance and reset, again electrolytic solution is joined in graduated cylinder, treat that the solution-stabilized volume of reading is afterwards v, graduated cylinder and electrolytic solution entirety are placed in reading quality value m on electronic balance, obtain the ratio that proportion is m and v.
After disassembling the battery after circulation, the pole cream that takes off complete is as much as possible tested, and in order to ensure the accuracy of data and comprehensive, does not generally get the lead plaster on the two-layer and two-layer pole plate in centre of outermost.
1, first pole cream is placed in vacuum drying oven, keeps 80 degrees Celsius, continue to vacuumize and make it dry, dry duration is generally 24 hours.
2, to be dried complete after, take out a part of pole cream, after grinding, carry out XRD test, test angle is 5-90 degree, sweep velocity be 5 degree per minute.
3, to be dried complete after, taking out complete pole cream utilizes conducting resinl to be bonded on the sample stage of scanning electron microscope, is placed in SEM instrument and observes, because pole cream own has higher electric conductivity, in order to keep the authenticity of pattern, so sample does not carry out the process of magnetron sputtering gold yet.The shooting multiple of pole cream sample is 1000 times and 5000 times.
In one embodiment, above-mentioned lead-acid battery method for testing performance can also comprise:
Detect the gas content of described lead-acid battery;
Judge whether described gas content exceedes preset value;
If so, then judge that the Performance Detection of described lead-acid battery is not passed through, otherwise judge that the Performance Detection of described lead-acid battery is passed through.
In the present embodiment, above-mentioned preset value can set according to the joint number of the model of lead-acid battery and battery cell.
As an embodiment, above-mentioned detect the step of the performance of described lead-acid battery according to described gas content after can also comprise:
Detect the size changing amount of described lead-acid battery;
Judge whether described size changing amount exceedes pre-set dimension;
If so, then judge that the Performance Detection of described lead-acid battery is not passed through, otherwise judge that the Performance Detection of described lead-acid battery is passed through.
Above-mentioned pre-set dimension can set according to the joint number of the model of lead-acid battery and battery cell.
Battery performance loop test is carried out under the hot conditions of 60 DEG C, after the fast charging and discharging of 30 circles, 4 hours 50A, having there is obvious distortion and expansion bulge in the battery case of lead-acid battery, makes lead-acid battery internal gas too high levels, thus affect the performance of lead-acid battery; There is deformation of cylindrical in lead-acid battery, mainly produces because pressure in body sharply increases, main cause have following some: (1) Investigation on safety valve pressure is too high, or safety valve block.When in body, pressure is increased to a certain degree, valve can not normally be opened, and certainly will cause deformation of cylindrical in this case.(2) floating charging is installed with too high, and charging current is large, causes oxygen evolution on positive plate to be accelerated, and having little time in negative pole compound, the temperature simultaneously in cell body rises also very fast, if exhaust is not in time, pressure reaches a timing, makes valve controlled sealed lead-acid accumulator occur deformation of cylindrical.(3) in valve controlled sealed lead-acid accumulator charge operation particularly in series battery, if carry out overcharge to electric battery, if the battery having quality bad often there will be the phenomenons such as internal gas compound is bad, thus there is bulge phenomenon.(4) because valve controlled sealed lead-acid accumulator belongs to barren liquor type design, reserved keeping away is left to the chemical combination of gas, and if have " rich solution " phenomenon, will stop that the oxygen of generation is diffused into negative pole, reduce the recombination rate of oxygen, pressure increase in body.Like this, the size of lead-acid battery just can change, if its size changing amount exceedes pre-set dimension, the Performance Detection of above-mentioned lead-acid battery is not just passed through.Generally, if lead-acid battery is after experiencing the loop test based on said temperature environment, the distortion of its apparent size is minimum, the extent of corrosion of positive/negative plate is minimum, coming off of active substance and pole cream is minimum, crackle between screen and pole cream occurs the latest, so substantially can determine that this type of battery is that Performance comparision is reliable.
In one embodiment, described in above-mentioned acquisition charge and discharge process, the process of the capacity data of lead-acid battery can comprise:
When carrying out cycle charge-discharge set point number to described lead-acid battery, detect the crackle data in described lead-acid battery between screen and pole cream;
Described capacity data is determined according to described crackle data.
By the anode plate of the different number of turns that do not circulate and circulate is compared, can find, along with the increase of cycle index, the extent of corrosion of pole plate increases, when circulation 30 circle, pole cream and the difference before not circulating are not too large, but when waiting circulating battery 60 to enclose, have occurred coming off and the slight erosion of pole plate of Topically active material.By the time the 90th circle, not only coming off of active substance is aggravated with the corrosion of pole plate, and also occurred crackle between screen and pole cream, crackle has also appearred in cream region, part pole, and the increase along with cycle index is described thus, and the labile factor of inside battery is being aggravated; The crackle data of respective regions also change thereupon.
By the comparison of lead-acid battery cathode pole plate, also the increase along with cycle index can be found, the corrosion of pole cream is more and more serious, coming off of active substance and pole cream is more and more obvious, after this circulating battery 90 and 120 circle, pole cream there will be obvious crackle, between pole cream and conductive grid plate, also occur crackle; Seemingly, active substance comes off from pole plate will inevitably cause the decay of capacity to the corrosion phenomenon comparing class of negative plates and anode plate; The appearance of the appearance of crackle or the probability event of other non-electronic contacts on pole plate, cause the internal resistance of pole plate to increase, thus the thermal effect of inside battery can be increased, internal temperature of battery will be caused thus too high, make water loss in electrolyte serious, reduce the serviceable life of battery.
In one embodiment, described in above-mentioned acquisition charge and discharge process, the process of the capacity data of lead-acid battery can comprise:
When carrying out cycle charge-discharge set point number to described lead-acid battery, obtain X-ray diffraction (XRD) spectrogram of described lead-acid battery positive pole;
Described capacity data is determined according to described XRD spectra.
In the present embodiment, carried out the test of XRD to the pole cream of (the 60th and the 90th circle) before circulation and after circulation, and irised out existing white bad point to the 90th and test, before circulation, the principal ingredient of positive pole pole cream is PbO
2, the PbSO of PbO and trace
4, the principal ingredient of negative pole pole cream is the PbSO of simple substance Pb and trace
4.
Circulation 60 and 90 circle, the principal ingredient terminating in the positive pole pole cream of half electricity condition is PbO
2, PbO and PbSO of trace
4.The XRD spectra of the positive pole before Integrated comparative circulation and after circulation, after cycling, PbO
2crystallinity increase, thermal effect large in galvanochemistry chemical process may be come from.Along with the carrying out of circulation, the peak width of XRD diminishes, and according to Scherrer formula (D=K λ/Bcos θ), shows PbO
2the size of crystal is along with the carrying out of circulation is in increase.The SEM photo of positive pole pole cream also shows that the particle diameter of the active substance in the cream of pole becomes increasing along with the increase of cycle index, and contacts also so fine and close not as good as origin pole cream with the electronics of conductive additive.Active material particle diameter in origin pole cream is shown between 50-200nm in scanning electron microscope (SEM) figure, distribution of particles is more even, and there is sufficient electronics to contact with adjuvant, along with the carrying out of circulating battery, the size of particle starts to occur increasing, and as shown in the SEM of the 60th and 90 circle positive pole pole cream, the size of active substance can reach several microns, and the contact distance between particle and particle also increases to some extent, and electronics contact has obvious reduction.Result of study in the past has shown that the increase of the size of active substance can make surface electrochemistry potential energy constantly reduce, and corresponding electrochemical activity is also more and more lower, and the appearance of this phenomenon is unfavorable for that between both positive and negative polarity, the reversible of electrochemical reaction carries out.And the electronics between particle with particle or between particle with conductive additive contacts and also can decrease, cause pole plate resistance to increase, respective battery internal resistance raises.As can be seen here, along with the carrying out of electrochemical reaction, the degree of reversibility of later stage active substance, also in continuous reduction, means that capacity is in continuous decay, final PbO
2irreversible PbSO can be converted to
4, thoroughly lose electrochemical reaction activity, compare the XRD spectrum of the 60th and 90 circle positive pole pole cream, can PbSO be found
4peak increase, also demonstrate supposition above, the active substance (PbO of chemical reversible reaction namely in the cream of positive pole pole, can be participated in
2and PbO) in reduction, directly cause the decay of capacity.
Circulation 60 and 90 circle, the principal ingredient terminating in the negative pole pole cream of half electricity condition is the PbSO of simple substance Pb and trace
4.The white dot occurred bottom 90th circle negative plates demonstrates this and infers, the pole cream of white is carried out XRD test by us, finds the PbSO that this material is corresponding pure
4and the pole cream in whole screen cell has all become white, lead complete deactivation in this grid is described, electrochemical reaction can not be participated in again, the lead plaster of these lattice is carried out to the titration of total lead content, result display lead content only has 56.56%, is starkly lower than normal contents (80% – 90%).The sulfation process of polar board surface can reduce the content of active substance in the cream of pole, the continuous reduction of battery capacity can be caused, and it can trigger the above-mentioned a series of subsidiary reaction that battery is stable that is unfavorable for, i.e. pernicious chain reaction can make the capacity reduction sharply of later stage battery.Microcosmic SEM photo relatively before and after the circulation of pole cream, also can find to be similar to the same phenomenon of positive pole pole cream, that is exactly the carrying out along with circulation, the size of active substance is in continuous increase, and by the time when the 90th circle, not only the size of active substance is close to 3-10 micron, nanoscale before being far longer than microcirculation, and the active substance before not circulating not only contacts closely, and it is evenly overall, do not have large close to particle, and the reunion degree of active substance after circulation obviously raises, and there is ganoid crystalline particle, size is larger.And the pattern of active material after circulation and the change of crystal structure all can reduce the electrochemical reversible degree of active substance, thus reduce utilization factor, cause capacity to decline thus.We adopt SEM to analyze the pole cream of failure site in the pole plates of 90 circles that circulated equally, and the active substance that can find in now pole cream all becomes smooth surface and size can reach the lead sulfate particle of 5-10 micron.Because the electric conductivity of this material own is poor, so this part lead sulfate particle loses electrochemical activity completely, not at participation discharge and recharge reaction contribution capacity.The injury mechanism that the acidifying that above interpretation of result confirms pole plate again causes battery life and capacity.
XRD according to both positive and negative polarity pole cream compares, and can find that the circulation along with battery is carried out, and is that PbSO has all appearred in both positive and negative polarity
4cumulative rises, and sulfate radical only may derive from electrolytic solution, along with PbSO
4continuous accumulation, electrolyte in electrolytic solution constantly reduces, this will cause the conductivity of electrolytic solution and ion mobility constantly to reduce, the reduction of above two parameters can significantly improve the internal resistance of battery, if internal resistance increases, thermal effect also just more obvious, therefore the corresponding corrosion speed accelerating pole cream, also can aggravate the dehydrating speed of electrolytic solution.Although the part water lost in this process can balance losing of sulfate ion to a certain extent, it is not so obvious that electrolytical concentration in electrolytic solution is declined, the speed that the mobility relaxing electronics and charge carrier in electrolytic solution reduces.But along with constantly carrying out of circulation, water can constantly lose, and the electrolytic solution in battery will constantly reduce, so now will produce more serious problem, namely electrolytic solution cannot infiltrate fully to pole cream.As in the case, active substance effectively can not participate in electrochemical reaction, and the minimizing that the electrolytic solution in battery system is continuing, the result caused thus is exactly the continuous decay of capacity, loses efficacy until battery is dry.
By the analysis of above result, can confirm in circulating battery process, PbSO
4irreversible generation be the major reason causing battery inactivation.Based on above result, we when design pole cream component, can add and suitably can suppress PbSO in the cream of pole
4the material generating or promote it to decompose, slows down PbSO
4accumulation, thus the rate of decay of battery capacity can be effectively reduced.Certainly the introducing of this material can not reduce the content of active substance in the cream of pole excessively, otherwise can reduce the whole volume of battery.
In one embodiment, described in above-mentioned acquisition charge and discharge process, the process of the capacity data of lead-acid battery can comprise:
When carrying out cycle charge-discharge set point number to described lead-acid battery, obtain the concentration of foreign ion in the electrolytic solution of described lead-acid battery and pole cream;
Described capacity data is determined according to described concentration.
Decay, the change of pole cream component of battery capacity are all relevant to the electrochemical reaction in cyclic process with the appearance of the phenomenons such as the corrosion of pole plate, and mainly caused by the change of electrolytic solution.Therefore pay close attention to the electrolytic solution change in cyclic process, effectively can monitor the performance of battery.The preparation of above-mentioned electrolytic solution strictly must select the special sulfuric acid of the secondary of GB4554-84 standard and distilled water.Commercial sulphuric acid and general water, because wherein containing the objectionable impurities such as iron, zinc, manganese, potassium, nitrogen, copper, can cause accumulator self discharge seriously and electrode corrosion and cause pole plate to damage, thus the serviceable life of shortening accumulator.
By detecting the foreign ion of pole cream, can find that the concentration of ferric ion is substantially similar, the plumbous detection of a large amount of existence to iron causes interference (being generally make testing result higher than actual content).The concentration impurity ion detected in these batteries does not have regularity, but the concentration impurity ion in the cream of pole must have certain scope, in theory, concentration impurity ion is more low better, so when detecting the foreign ion in the battery of same batch, its concentration must become to concentrate on the region near 0, and can not become normal distribution that intermediate value is larger or the distribution near maximal value.So, if when comparing battery quality, the foreign ion in the cream of pole can be added up, calculate the capacity data of above-mentioned lead-acid battery according to above-mentioned foreign ion, and then carry out the detection of lead-acid battery performance.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this instructions is recorded.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
