The VRLA battery is in the high temperature circulation charging process, and key reaction is for discharging and recharging the reaction of reaction and positive grid corrosion, and the inside battery reaction is as follows:
Anodal: pbO
2+ 3H
++ HSO
4 -→ pbSO
4+ 2H
2O-2e and Pb+O
2→ PbO

++ 2e and 2H
+→ H
2-2e
More than 2 pairs grip altogether reaction and consisted of the key reaction principle of high temperature circulation battery, under hot conditions, according to the Arrhenius equation, more than reaction is all accelerated.
Electrolyte stratification is the main failure mode of the early stage capacitance loss of VRLA battery, there is certain Action of Gravity Field in electrolyte itself, do not resemble the gas that produces that charges the flooded batteries at charge and discharge cycles process VRLA battery and play the effect of stirring electrolyte, thereby cause battery electrolyte existence lamination to a certain degree, obvious especially in high type battery, the top concentration of electrolyte is low, and the bottom concentration of electrolyte is high.Behind electrolyte stratification, for stand up pole plate with a slice for, same electrode variable concentrations can cause the surface electrical potential difference, according to formula: E=E

4), pole plate bottom current potential is high than the top current potential; In addition, when battery discharge, because pole plate top Ohmic resistance is lower, battery top begins first discharge, it is lower that concentration of electrolyte is compared the bottom, can form like this this chemical reaction process: place the negative plate bottom vertically to the upper plates depolarising of charging, the top of every pole plate is divided and often is in the full charge state like this, and the bottom is divided and often is in discharge condition.If things go on like this, thereby cause the battery capacity loss, cycle life reduces, and finally causes the storage battery battery to lose efficacy.This problem is for the sleeve configuration storage battery, particularly serious.
The positive/negative plate level is sleeping puts and can address the above problem, yet, for the 12V sleeve configuration storage battery that is applied to rack, its level is sleeping puts rear owing to be subject to the restriction of cabinet dimensions, can cause its capacity to be lower than traditional 12V sleeve configuration storage battery, therefore, in the past, be used in the internal structure that still adopts widely pole plate to place vertically in the 12V high temperature cyclic elongated structure valve-controlled type sealed lead acid of rack.
Theoretical according to AOS: along with the carrying out of circulating battery, positive active material carries out dilation repeatedly, neck region between the particle diminishes, so that the contact between the active material particle becomes more and more worse, the electric conductivity variation, finally cause the active material softening and shedding, battery capacity obviously decays, battery failure.Therefore improving the active material charge acceptance and improving the positive active material grain structure is the key that realizes the battery long circulation life.
At high temperature, according to the Arrhenius equation, 10 ℃ of the every risings of battery temperature, positive grid corrosion speed adds accompanies, the float life of battery reduces by half, that is to say under common VRLA battery quality guarantee life-span 25 ℃ of conditions to be 5-8 that when temperature is brought up to 35 ℃, the life-span of common VRLA battery only has 2-4.
VRLA battery case material is generally selected the ABS material at present, and the heat distortion temperature of ABS is about 90 ℃.The assembling pressure of VRLA battery is generally larger, and also there is certain air pressure in inside battery, the rising of temperature, so that ABS intensity descends, this is so that battery easier generation bulging under hot conditions.Under actual 55 ℃ of floating charges test, the bulging of ABS is probably at 1.5%-2%.The bulging of ABS groove, the easier increase that causes floating current further causes thermal runaway.

Embodiment
Put 1.1 the pole plate level is sleeping
There is certain Action of Gravity Field in electrolyte itself, play the effect of stirring electrolyte at the charge and discharge cycles process VRLA battery gas that produces that unlike flooded batteries, charges, thereby cause battery electrolyte existence lamination to a certain degree, obvious especially in high type battery, the top concentration of electrolyte is low, and the bottom concentration of electrolyte is high.Behind electrolyte stratification, for stand up pole plate with a slice for, same electrode variable concentrations can cause the surface electrical potential difference, according to formula: E=E

4), pole plate bottom current potential is high than the top current potential; In addition, when battery discharge, because pole plate top Ohmic resistance is lower, battery top begins first discharge, it is lower that concentration of electrolyte is compared the bottom, can form like this this chemical reaction process: place the pole plate bottom vertically to the upper plates depolarising of charging, the top of every pole plate is divided and often is in the full charge state like this, and the bottom is divided and often is in discharge condition.The pole plate level makes with a slice pole plate top and the bottom to be under the identical sulfuric acid concentration after crouching and putting, and can eliminate with a slice polar board surface voltage difference, makes the bottom pole plate also be in normal full charge state, has improved active material conductivity and the utilance of bottom pole plate.Fig. 2 has shown the contrast of conventional batteries and the sleeping battery cycle life of putting of pole plate level, and sleeping discharge pond has long cycle life.Its experimentation is as follows
Select same batch of positive plate, negative plate, dividing plate, cell through lid, through same assembling, acid filling, the electricizing activation operation forms 6 finished product batteries altogether.One group by normally standing up test, the called after conventional batteries, another group pole plate level crouches and puts test, the sleeping discharge of called after pond, carry out 100%DOD floating charge cycle life contrast test in 50 ℃ of environment, floating charge voltage is 2.25VPC, when capacity be lower than rated capacity 80% the time, battery testing finishes, and obtains Fig. 2.As can be seen from Figure 2, the sleeping pond of discharging has longer cycle life.
1.2 anode diachylon adds 4BS
As everyone knows, 4BS is the active path of avoiding the early activity material softening because crystal grain is large, and the active material mechanical strength is good.The size of 4BS crystallite dimension has obvious electrochemical action with distribution to the pole plate cycle performance, uncontrollable by 4BS amount and grain size that production process (paste mixing at high temperature and hot setting) control obtains, be difficult to guarantee the consistency of pole plate, and be not expected.The present invention adds a certain proportion of 4BS and carries out and cream as crystal seed in anode diachylon, so that a large amount of 4BS is evenly distributed in the pole plate, changed the pore structure of pole plate, thereby reached the effect that improves the life-span.What Fig. 3 showed is the cycle life comparison diagram that anodal interpolation 4BS battery and conventional batteries are carried out.
Select same batch of positive grid, negative plate, dividing plate, the groove lid makes 9 semi-finished product batteries, and first group of positive grid is coated with normal anode diachylon, the called after conventional batteries, it is the anode diachylon of 1% 4BS that second group of positive grid is coated with the interpolation mass percent, the called after anode diachylon adds the 1%4BS battery, it is the anode diachylon of 10% 4BS that the 3rd group of positive grid is coated with the interpolation mass percent, the called after anode diachylon adds the 10%4BS battery, through same assembling, acid filling, after the electricizing activation operation, form the finished product battery.Carry out 100%DOD floating charge cycle life contrast test in 50 ℃ of environment, floating charge voltage is 2.25VPC, when capacity be lower than rated capacity 80% the time, battery testing finishes, and obtains Fig. 3.As can be seen from Figure 3, anodal interpolation 4BS content is higher, and more to the improvement of battery cycle life, anode diachylon adds the cycle life that 4BS has improved battery.
Can improve cycle life according to the above-mentioned pole plate horizontal positioned that experiment showed,, and its raising effect to cycle life is more obvious than adding 4BS.But owing to limit by applied interior of equipment cabinet shape, must be able to satisfy rack and install, such as, as shown in Figure 4, they are formed by connecting by 4 12V sleeve configuration storage batterys, and the final profile of the present invention as much as possible profile with conventional batteries is consistent.Scheme for the pole plate horizontal positioned, because the arrangement of pole plate and the variation of placement direction, in the situation that is subject to the cabinet dimensions constraint, the pole plate size is forced to change, therefore, and with regard to embodiment 1, improved cycle life, but under same profile, its design capacity can be affected, a little less than conventional batteries.
Further, shown in Fig. 1,4 and 5,14,15,16, it is the relative structure of lug diagonal that storage battery of the present invention adopts utmost point group, namely for a utmost point group, the lug of all positive plates all is in a side of positive plate one end, and the lug of negative plate is in the opposite side of the end opposite of negative plate.
With reference to Fig. 5, the lug of traditional 12V sleeve configuration storage battery is all drawn in the pole plate upper end.The grid because electric current is flowed through, produce voltage drop at each node of grid, the voltage drop that different nodes produce is different, little near the pressure drop of lug place, large away from the pressure drop of lug place, for the pole plate of traditional 12V sleeve configuration storage battery, cause pole plate bottom active material utilance not enough, and pole plate top too utilize.
And adopt technical scheme of the present invention, the current density of grid so that flow through, the voltage drop more uniformity that distributes, the active material utilization at pole plate two ends approaches, thereby optimized grid design, reduced the voltage drop of pole plate, the path of having improved electric current, reach and improve the pole plate charge acceptance, improve the purpose of active material utilization.
Fig. 6 is traditional 12V sleeve configuration battery grid and the battery grid voltage drop distribution comparison diagram of the present invention that computer simulation records.The computer model experiment is based upon on the two boards bar phantom basis, a grid lug is the arrangement that above-mentioned conventional batteries adopts, another piece grid lug is arrangement of the present invention, the grid shape of two grids is identical, utilize Abaqus software to set up pressure drop distribution curve between each grid node, thereby obtain Fig. 6.
Adopt as can be seen from Figure 6 after the technological means of the present invention the voltage drop relative conventional batteries that distributes more even.
Obtain in computer simulation on result's the basis, above-mentioned 12V sleeve configuration storage battery is carried out the initial capacity contrast test with the pole plate horizontal positioned that adopts the present invention program, utmost point group for the storage battery of the relative structure of lug diagonal, and the capacity of discovery battery can improve about 3%.
Select same batch positive plate, negative plate, dividing plate makes 6 semi-finished product batteries altogether, the called after conventional batteries, the relative upper and lower side of another group called after lug diagonal is drawn battery, and through same assembling, acid filling after the electricizing activation operation, forms the finished product battery.Both differences only at the positive and negative lug of conventional batteries at homonymy, the relative upper and lower side of lug diagonal is drawn the positive and negative lug of battery at the place, diagonal angle of heteropleural.Under normal temperature condition, carry out 10 hour rate initial capacity contrast tests by YD/T 799-2002 standard.Obtain Fig. 7 according to test data.
As can be seen from Figure 7, adopt positive and negative lug in the setting of the diagonal angle of heteropleural, the capacity of battery promotes about 3%.
Grid has collector and supports the double action of active material in battery.According to the Arrhenius equation, 10 ℃ of the every risings of battery temperature, positive grid corrosion speed adds accompanies.If positive grid corrosion distortion, the collector effect of positive grid will reduce greatly, and the performance of battery obviously descends.Therefore under the high temperature applied environment, the excellent corrosion that improves positive grid is important.
The present invention adopts more corrosion resistant slicker solder silicon ternary alloy three-partalloy as positive grid alloy material, alloy component (mass percent): tin 0.1%～1.0%, and silicon 0.01%～0.1%, surplus is plumbous.Element silicon adds in the terne metal can become large so that grid alloy is cast rear crystal grain, and reduce at the grain boundary corrosion position, thus so that its corrosion resistance raising.It is the core that the interpolation of silicon has reduced grain nucleation that its crystal grain becomes large reason, causes coarse grains.
What Fig. 8 showed is positive grid corrosion picture contrast after the high temperature accelerated corrosion life test of the same terms and time.This experiment selects plumbous calcium tin positive grid and the slicker solder silicon positive grid of casting of casting to carry out the rotproofness contrast.Lead-calcium-tin alloy component (mass percent) wherein: calcium: 0.06%, tin 1.2%, surplus is plumbous; Slicker solder silicon alloy component (mass percent): tin 0.1%, silicon 0.01%, surplus is plumbous.At 60 ℃ of H
2(density: 1.304g/cm3), it is the relative Hg/Hg of 1.35V-1.38V(that two grids of above identical lattice structure are applied anode potential to SO4 solution
2The SO4 electrode), etching time is 2 months.After the end, make grid sample observing samples grid corrosion situation under metallomicroscope, the result obtains Fig. 8.By comparison diagram 8 as can be known, adopt slicker solder silicon ternary alloy three-partalloy as positive grid alloy material, the relative lead-calcium-tin alloy of its corrosion resisting property is better.Tin content increase the corrosion resistance that can improve grid, what of number of grain boundaries have certain relation with silicone content, and silicone content is more in formula range provided by the invention, and its crystal boundary is fewer, corrosion-resistant better, but tin content surpasses 1.0%, and after silicone content surpassed 0.1%, the continuation of tin, silicone content increased, crystal boundary and corrosion-resistant on improvement not obvious, so tin content is 0.1%～1.0%, silicone content is comparatively suitable between 0.01%～0.1%.
Battery case is the reservoir vessel of VRLA battery, generally adopts the ABS material as container, under hot conditions, there is certain bulging in battery case owing to be subject to cell internal pressure, so that pole plate and dividing plate close contact no longer, thereby have influence on the performance of battery, might cause thermal runaway under the ultimate attainment condition.Battery case of the present invention is selected take ABS as base material, in the ABS material, add (mass percent) N-phenyl maleimide 0.1%～10%, glass fibre 0.1%～10%, talcum powder 0.1%～10%, styrene-grafted maleic anhydride 0.1%～10%, it is structurally-modified that the cell through lid material is carried out intramolecule, thereby the groove cover material is not deformed under higher temperature and external force, thereby improve the anti-deformation of battery case under hot conditions.The ABS material improves 10 ℃～30 ℃ relatively.
