The present invention relates to closed lead acid storage battery, especially relevant with the life-span closed lead acid storage battery long, that reliability is high that possesses based on the dividing plate of glass fibre.
Background technology
In the closed lead acid storage battery that automobile is used or battery vehicle is used, the cushion thin plate of glass fibre is practical as dividing plate, and as the practice of the absorbency that will improve dividing plate, improvement electrolyte retentivity, that is: making glass fibre and inanimate matter powder combinations has been technique known.
As this dividing plate, be with average diameter 0.5 μ m～1.0 μ m to contain the alkali silicate glass fibre be the fiber of main body and be 100m with the specific area
2The above SiO 2 powder of/g is that the powder of main body carries out wet type and mixes and copy, and when above-mentioned fiber twines mutually, above-mentioned powder particle is got involved form between fiber and the fiber lead accumulator with dividing plate (with reference to patent documentation 1: the spy opens clear 60-221954 communique).
At patent documentation 1 (claims, hurdle, the 2nd row～bottom right reciprocal, the 1st page of hurdle, lower-left the 7th row, the 2nd page of upper right hurdle the 1st row～the 5 row, the 2nd page of hurdle, lower-left the 4th row～the 11 row, the 3rd page of hurdle, lower-left the 6th row～the 11 row) in, record in the closed lead acid storage battery that the cushion thin plate with the glass fibre below the average diameter 1 μ m uses as dividing plate, when the pole plate height for example is large-sized battery more than the 180mm, because the suction range that the capillarity phenomenon of fiber causes reduces, so the electrolyte maintenance dose on the top of cushion thin plate is than bottom much less, produce so-called electrolyte and become stratification, can not obtain the such problem of performance of expectation.The invention of patent documentation 1 is, is that 0.5 μ m～1.0 μ m contain the alkali silicate glass fibre and specific area is 100m by using average diameter
2The SiO 2 powder that/g is above, by containing the waterglass shape adhesion coating that produces on the alkali silicate fiberglass surfacing technology that both address this problem of adhering, rather than the filling rate of the compaction force by adjusting the pole plate group, electrolyte solves.
In addition, to prevent that electrolyte from becoming stratification etc. is purpose, in closed lead acid storage battery, pole plate group separator uses with the baffle plate of the glass fibre more than the fiber diameter 6.0 μ m as main body, the acid proof inorganic particle that can keep electrolyte to the maximum interpolations 2% of sulfuric acid electrolyte, for the pole plate group who is made of positive plate, negative plate, baffle plate, the drying regime before injecting electrolyte is with 10～50kg/dm
2Pressure it is carried out compacting (with reference to patent documentation 2: the spy opens flat 7-94206 communique).
Though in the patent documentation 2 (claims 2 in claims, paragraph 0004～0005,0015) in, disclose because compacting pole plate group, between pole plate and baffle plate, be difficult to produce the technology that the gap prevents into stratification, but also put down in writing owing to can not maintenance exert pressure equably, when with above 50kg/dm
2Pressure compacting pole plate group time, battery case just expands, in addition, because inorganic particle adds in electrolyte, rather than in based on the baffle plate (dividing plate) of glass fibre, add, so in order to prevent the one-tenth stratification of electrolyte, for by based on the interpolation of positive plate, negative plate, glass fibre the pole plate group that constitutes of the dividing plate of inorganic particle, not talkative permission is to surpass 50kg/dm
2The pressure of (about 49kpa) carries out compacting to it.
The prior art that applies very high compaction force as the pole plate group (utmost point group) to lead accumulator has: with clad formula positive plate and thickener formula negative plate, protect the closed metal clad type lead accumulator that the mutual lamination of fluidity dividing plate forms the pole plate group by tabular, this battery is that the pole plate group is subjected to 40kg/dm
2Above compactness compacting, to protect the fluidity dividing plate be (with reference to patent documentation 3: the spy opens flat 5-198311 communique) based on the glass fibre of fiber diameter below 0.4 micron; Will be between positive plate and negative plate clamping glass isolator and lamination utmost point group, be 30～80kg/dm with this utmost point group's compaction force
2Be received into negative absorption closed lead acid storage battery in the battery case (with reference to patent documentation 4: the spy opens flat 11-185764 communique); With positive plate and negative plate by the cushion thin plate lamination that constitutes by glass fibre etc. the pole plate group be received in the closed lead acid storage battery in the battery case, on its lamination direction, adding 39200N/m on the above-mentioned pole plate group
2The closed lead acid storage battery that above group presses (with reference to patent documentation 5: the spy opens the 2002-42857 communique).
In patent documentation 3 (claims, paragraph 0005,0009), disclose by compactness is set at 80kg/dm
2(about 78.4kpa) makes the contact area of positive plate and dividing plate become big, and discharge capacity becomes big situation, but does not relate to life-saving; The invention of patent documentation 4 (claim 3 of claims, paragraph 0018,0023), for the compacting positive plate be provided, suppress elongation, long closed lead acid storage battery of life-span, pole plate group's compaction force is set at 30～80kg/dm
2, but concrete disclosed compaction force is to 35kg/dm
2(about 34.3kpa); The invention of patent documentation 5 (claim 1 in claims, paragraph 0014～0019,0034～0038) in order to suppress the distortion of positive plate and negative plate, is pressed along with the pole plate group being received in the battery case inchmeal additional clusters, by adding 39200N/m
2(about 39.2kpa)～98000N/m
2Group (98kpa) presses, improved life-span height ratio flash-over characteristic, but when inserting the pole plate group to battery case, inserting the group that can not apply on the pole plate group at first more than the 39.2kpa presses, in addition, above-mentioned any one invention is not to use the dividing plate that contains SiO 2 powder, neither turn to purpose to prevent the electrolyte stratification.
In addition, relate to electrolyte content, have the electrolyte content impregnation of 0.9～1.0 times of scope that to be equivalent to be received into the spatial volume of the pole plate group in the battery case to remain on closed lead acid storage battery among the pole plate group (with reference to patent documentation 6: the spy opens clear 60-185370 communique).
Patent documentation 6 (claims, the 2nd page of upper left hurdle the 15th row～the 18 row) invention, when the not enough pole plate group's of electrolyte content spatial volume 0.9 the time, the absorption reaction of gas just takes place, capacity is reduced, therefore to be set at 0.9～1.0 times of scope, do not allow electrolyte content be set at not enough pole plate group spatial volume 0.9.
In the big capacity closed lead acid storage battery that the height of pole plate uprises, in order to make the battery of (electrolyte the becomes stratification) high performance and long service life that stagnates partially that prevents inside battery electrolyte up and down, the electrolyte content of closed lead acid storage battery is reduced to suitable scope, make the electrolyte of pole plate inside remain in the hole of positive and negative electrode and baffle plate (with reference to patent documentation 7: the spy opens clear 60-243976 communique).
Patent documentation 7 (the 1st, the 2nd of claims,～the 2 page of upper left hurdle of the 5th row reciprocal, the 1st page of hurdle, bottom right the 4th row) upward discloses, the electrolyte content of average each groove is set at 2.3～3.5 times of the total pore space of positive/negative plate, but the total pore space of pole plate group that does not openly comprise baffle plate (dividing plate) is made much.
Yet, the automobile that is requiring high output with and battery vehicle usefulness closed lead acid storage battery in, taking the distance between pole plate shortened etc. reduces the method for liquid resistance.,, just cause and soak into short circuit that the SiO 2 powder of putting down in writing not only has the effect that keeps electrolyte, and the effect that prevents to soak into short circuit is arranged in above-mentioned known document if the distance between pole plate shortens.When the dividing plate of SiO 2 powder being sneaked into glass fibre was used in closed lead acid storage battery, even the pole plate height is the battery about 130mm, the liquid that also can produce electrolysis became the problem of stratification as can be known.

Embodiment
Below, illustration embodiments of the present invention, but the invention is not restricted to following execution mode.
Glass fibre can use the glass fibre of the market sale of common use on dividing plate.Average diameter is unqualified, but is preferably 0.8 μ m～3.5 μ m.
SiO 2 powder can use dry process silicon dioxide or wet silicon dioxide or the diatomite etc. of common use on dividing plate, but preferably its specific area also is 100m
2More than/the g.This is because good to the wetability of acid, and specific area is big more, and to become powder superior more to the dispersion stabilization of water.
The amount of the SiO 2 powder of anti-sulfuric acid does not limit, and contains 1～40% of separator but can make, and is preferably 5～30%.If 1% of not enough separator just lacks the effect that absorbency improves; If 40% of overweight, resistance is just too high, the shortcoming that also exists SiO 2 powder to come off easily.
The inanimate matter powder of glass fibre and anti-sulfuric acid and the wet type of carrying out are mixed and to be copied, but beyond glass fibre, also the synthetic fibers of polyester fiber etc. can be mixed and copy.
Pole plate group's compaction force is the pressure that is equivalent to pole plate group with the drying regime unit are during compacting on the lamination direction.This compaction force is to reduce slowly before about 70% at the filling rate that reaches electrolyte from drying regime, thereafter before this filling rate reaches about 80～90% during in slowly rise, from here on when the filling rate of electrolyte is reduced to 70% left and right sides from about 80～90%, compaction force is than much lower when drying regime begins to rise to 70% left and right sides.For example, the compaction force of drying regime is 60kpa; When the filling rate of electrolyte is about 70% the time, compaction force becomes about 30kpa; Thereafter when this filling rate be about 90% the time, compaction force is about 40kpa, is reduced to approximately 70% the time when this filling rate from here on, compaction force becomes about 20kpa.
When pole plate group's compaction force is 60kpa when above, between pole plate up and down the difference in specific gravity of electrolyte be that cycle life significantly improves below the 0.04d.If not enough 60kpa, even the electrolyte filling rate of pole plate group total pore size volume is 92% relatively, the difference in specific gravity of electrolyte is also above 0.04d up and down between pole plate, and cycle life shortens.
Even pole plate group's compaction force is more than the 60kpa, when the electrolyte filling rate of relative pole plate group total pore size volume is bigger than 92%, between pole plate up and down the difference in specific gravity of electrolyte occasion above 0.04d is also arranged; Even but the sort of occasion, pole plate group's compaction force and the occasion of not enough 60kpa relatively, between pole plate up and down the difference in specific gravity of electrolyte diminish, cycle life improves.
The upper limit about pole plate group compaction force is unqualified, but from the angle that the pole plate group is convenient to assemble, is preferably below the 140kpa.
Pole plate group total pore size volume is tried to achieve according to following formula, and the electrolyte filling rate of pole plate group total pore size volume removes the volume of the electrolyte that injects battery case and calculates by pole plate group total pore size volume relatively.
Pole plate group total pore size volume=positive plate pore volume+negative plate pore volume+partition pores volume
Positive plate pore volume=positive plate volume-positive active material volume-anodal lattice body volume
Negative plate pore volume=negative plate volume-negative electrode active material volume-negative pole lattice body volume
Partition pores volume=dividing plate volume * (partition pores rate)
When the electrolyte filling rate of relative pole plate group total pore size volume is 92% when following, up and down electrolyte density difference is that cycle life significantly improves below the 0.04d between pole plate.When bigger than 92%, even pole plate group's compaction force is 60kpa, the difference in specific gravity of electrolyte is above 0.04d up and down between pole plate, and cycle life shortens.
Even the electrolyte filling rate of pole plate group total pore size volume is below 92% relatively, when the not enough 60kpa of pole plate group's compaction force, the difference in specific gravity of electrolyte also has the occasion above 0.04d about between pole plate, even but the sort of occasion, with the electrolyte filling rate of relative pole plate group total pore size volume than 92% big occasion relatively, the difference in specific gravity of electrolyte also diminishes about between pole plate, and cycle life improves.
Lower limit about the electrolyte filling rate is unqualified, but when less than 76%, sulfuric acid amount (electrolyte content) tails off, discharge capacity tails off, and, because the contact area of electrolyte and active material tails off, the height ratio flash-over characteristic reduces, so be preferably more than 76%.
Below, further describe the present invention based on embodiment, but the invention is not restricted to following record, the positive plate of the battery of test method or formation, negative plate, positive active material, negative electrode active material, dividing plate, electrolyte and cell shapes etc. are arbitrarily.
