Know-why of the present invention
(1) the conventional charge and discharge process analysis of excide battery
The electrochemical reaction that excide battery is corresponding is
Negative pole Pb-2e+SO
4 2-=PbSO
4
Positive pole PbO
2+ 2e+SO
4 2-+ 4H
+=PbSO4+2H
2o
net reaction is
As can be seen from net reaction, the active material in excide battery has metallic lead (Pb), brown lead oxide (PbO
2), sulfuric acid (H
2sO
4), lead sulfate (PbSO
4) and water (H
2o) 5 kinds of materials.For valve-control sealed excide battery, nearly all there is not loss problem (water may have insubstantial loss) in them, therefore sulfuric acid and water can not affect the useful life of excide battery, in all the other 3 kinds of materials, metallic lead can keep good conductivity, also the useful life of excide battery can not be affected, only have brown lead oxide and lead sulfate, its conductivity can be reduced along with growing up of crystal grain, consequently, cause excide battery internal resistance to increase, when excide battery is discharged, terminal voltage reduces, and must improve charging voltage during charging; And when charging voltage reaches decomposition voltage (containing the overpotential) of water, not only charge efficiency greatly reduces, and the adverse consequencess such as excide battery explosion, dehydration may be caused.
From analyzing above, the useful life of excide battery be extended, must see following some:
A. as can be seen from net reaction, discharge process (to the right) discharges the spontaneous process of electric energy for excide battery outside system, and charging process (left) is then the nonspontaneous process needing to provide to excide battery system electric energy;
B. newly-generated in electrochemical reaction process solid particle (comprising brown lead oxide or lead sulfate) is general less, and conductive capability is good;
C. little solid particle is grown up and is become the difficult bulky grain crystal needs the conducted electricity longer time;
D. excide battery, particularly power excide battery in use, can not realize " entirely fill and entirely put ", often be in the state that existing brown lead oxide has again lead sulfate, several hours, even several days, brown lead oxide or lead sulfate not may have grown into the bulky grain being difficult to conduct electricity, but some months, even several years, that is just unavoidable;
E. excide battery has allowed three kinds of states to exist: state I for positive pole only have brown lead oxide, negative pole only has lead, both positive and negative polarity is all without lead sulfate existence (full power state); State II all has lead sulfate to exist for both positive and negative polarity; State III be positive pole without brown lead oxide, both positive and negative polarity is all containing a large amount of lead sulfates (complete electroless state);
From e, the excide battery newly changed into and with rear be full of in time electricity excide battery be in state I; State II is in when (discharge process) and partial discharge are not full of again electricity in time during excide battery work; Can, lower than under the professional etiquette restriction of 1.75V, except the excide battery of designer of the present invention, second excide battery may be had to reach state III at current single lattice excide battery discharge voltage.
From c, d, when excide battery is in state II for a long time, the lead sulfate on both positive and negative polarity, must sulfation through 2 to 3 years, and namely grow up to bulky grain by granule, and particle looks more greatly faster, conductivity is poorer.From a, lead sulfate becomes plumbous and brown lead oxide is nonspontaneous process, needs, to excide battery charging, when hindering larger within it, must increase charging voltage, and this to be by the restriction of water decomposition voltage, and excide battery finally certainly will be caused to scrap.
Excide battery in use, if can " with filling " (with after be full of electricity immediately), then general still can hold mode I in de-activation procedure for excide battery.Really, through 2 to 3 years, brown lead oxide on positive pole also can become bulky grain by granule, make resistive in excide battery large, discharge voltage (electric current) reduces, but from a, discharge process is spontaneous reaction, we can use the present invention in several hours, first allow excide battery self-discharge, then to its suitable reverse charge, from b, brown lead oxide on positive plate will all be converted to the good granule lead sulfate of newly-generated conductive capability, from e, such excide battery closes on state by what be in state III, then being full of electricity to excide battery again makes it return to state I, thus make excide battery enter into second life cycle.
As can be seen here, as long as the structure of excide battery not destroyed (comprising shell, electrode and electrode diaphragm), active material (above-mentioned 5 kinds, particularly water) do not lose, use the present invention, " with filling; discharge in good time ", the useful life of excide battery will extend at double.
Should particularly point out, current excide battery operator always reminds excide battery user by traditional concept: " charging times of excide battery is certain, fills once less once ".This makes user dare not " with filling ", and consequently " current with on the both positive and negative polarity of excide battery, all there is " the bulky grain lead sulfate " of varying number.It can be asserted that: if there is the lead of 10% mole to change into bulky grain lead sulfate, then the ability of this excide battery can only be returned to former new battery 90% at most by the present invention.Therefore, manage businessman of the present invention and don't fail to tell that service object will adhere to " with filling ".
(2) the reverse charge process analysis procedure analysis of excide battery
In the excide battery spontaneous discharge later stage, as discharging current≤1000mA, its open circuit voltage is still at more than 6V, standing a period of time measures again, its open circuit voltage can rise further, this shows positive plate to still have remaining bulky grain brown lead oxide, these residual bulky grain brown lead oxide, specific area is little and conductive capability is poor, if carry out electrochemical reaction voluntarily by it by means of only connection external circuit and reach chemical balance, need the endless time theoretically, if now to its reverse charge, then can shorten said process widely.The standard electrode potential of excide battery both positive and negative polarity is:
1. negative pole Pb-2e+SO
4 2-=PbSO
4(-0.3553V)
2. positive pole PbO
2+ 2e+SO
4 2-+ 4H
+=PbSO4+2H
2o (1.685V)
By the standard electrode potential of above electrode reaction, can find out, lead during reverse charge on negative pole preferentially reacts and 1. generates lead sulfate, and be 2. difficult in early days react generates brown lead oxide; 2. positive pole preferentially reacts, and is difficult to react 1. generate lead.Certainly, if continue reverse charge, then the both positive and negative polarity of excide battery can be put upside down sooner or later, and finally damages excide battery.But, a small amount of plumbous to generate even if positive pole has, negative pole has a small amount of brown lead oxide to generate but does not reach the degree destroying both positive and negative polarity structure, also it doesn't matter, because excide battery is placed a period of time, the bulky grain brown lead oxide be not exhausted if positive pole still has, then all can there is following chemical reaction in both positive and negative polarity separately
③
Thus be all converted into lead sulfate respectively.As can be seen from 3. formula, this process can releases heat, adds the heat that discharge process produces, must excide battery be caused to generate heat, and therefore to excide battery reverse charge, attentional manipulation 12V excide battery cell side surface temperature can not more than 40 DEG C.Certainly, in order to accelerate reverse charge process, also the temperature-fall periods such as ventilation, cryostat can be taked.
If the bulky grain brown lead oxide that positive pole has not been exhausted, so for a small amount of lead, brown lead oxide that positive and negative electrode generates, when follow-up charging normal, they also can be consumed, thus recover the original appearance of processed excide battery completely.
