Know-why of the present invention
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
4with water H
2o5 kind material.For valve-control sealed excide battery, they nearly all do not exist loss problem water still may have insubstantial loss, 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 can not affect the useful life of excide battery, 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 the decomposition voltage that charging voltage reaches water contains overpotential, not only charge efficiency greatly reduces, and may cause the adverse consequencess such as excide battery explosion, dehydration.
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 discharges the spontaneous process of electric energy for excide battery to the right outside system, and charging process is then left the nonspontaneous process needing to provide to excide battery system electric energy;
B. newly-generated in electrochemical reaction process solid particle comprises 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, all there is full power state without lead sulfate in both positive and negative polarity; 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 the complete electroless state of a large amount of lead sulfates.
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, the brown lead oxide on positive pole also can become bulky grain by granule, made 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, allow excide battery discharge, from b, such brown lead oxide will all be converted to the good granule lead sulfate of newly-generated conductive capability, is then full of electricity to excide battery again and 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 is not destroyed comprise shell, electrode and electrode diaphragm, above-mentioned 5 kinds of active material, particularly water does not lose, and uses the present invention, and " with filling, discharging ", the useful life of excide battery will extend at double in good time.
1. to the new battery of the excide battery newly changed into, with filling, ensure that, under non-charging and discharging state, excide battery is in state I all the time.
2. charger adopts the charging of pulse constant voltage to described excide battery, and charging voltage should be less than the decomposition voltage of water.
3., when the discharge voltage of described excide battery can not meet instructions for use, with the present invention, this excide battery is discharged.Charging method is, by load from big to small, points 4 times, each electric discharge 1 hour, even longer time but be always consuming timely no more than 8 hours, until indicator light completely can not luminescence.
4. abundant discharge off, charges to state I with constant voltage charger immediately, then the serviceability of excide battery can be made almost to return to and newly change into state.
