Description
Technical field
The invention belongs to the storage battery field, be specifically related to a kind of manufacture method of colloid electrolyte lead-acid accumulator.
Background technology
Lead acid accumulator is easy to get because of raw material, makes simply, and stable performance, characteristics such as low price and great variety of goods still dominate in various secondary chemical sources of electric energy so far, occupy the maximum market share.Valve controlling sealed battery has appearred in the sixties in 20th century in the world, and its non-leakage acid solution is seldom discharged acid mist during charging, need not add dilute sulfuric acid and pure water in the use, thereby be non-maintaining.Valve controlling sealed battery comprises two types on absorption type battery and colloidal electrolyte battery.The former is adsorbed on dilute sulfuric acid electrolyte wherein with superfine glass fibre partition board (AGM), and the internal resistance of cell is little, and electrolyte content is relatively low, and heavy-current discharge performance is good, is suitable as start type battery and various emergency power supply (UPS).The AGM battery is the lean solution formula, electrolyte stratification can occur in discharging and recharging, and many, the weak heat-dissipating of big, the living heat of floating current is not suitable for deep discharge and recycles, and easily produces bulge and thermal runaway phenomenon, and its service condition is subjected to many restrictions.Colloid storage battery is to add SiO in dilute sulfuric acid
2The gel of class makes electrolyte become gelinite, loses flowability, and the complete no leakage of battery has been eliminated the electrolyte stratification phenomenon.Colloid storage battery is a pregnant solution type, its floating current is little, give birth to heat less, big, the good heat dissipation of specific heat, so be suitable for dark cycle applications, so more safe and reliable than AGM battery, it is long to recycle the life-span.In many conventional batteries and the inapplicable occasion of AGM battery, can use colloid storage battery.But the colloid storage battery internal resistance is high slightly, and its specific energy approximately reduces by 10%, its manufacturing process complexity, and prices of raw and semifnished materials height is so the price of colloid storage battery is more much higher than conventional batteries and AGM battery.At present, be that the countries in the world company of representative makes colloid storage battery and all adopts the U.S. to reach polyester that auspicious Mick (DARAMIC) company produces to apply the micropore PVC SiO that phenolic resins dividing plate or European A Moxier (ARMER-SIL) company produce with German sunlight storage battery company
2Dividing plate, its price is at 40-60 yuan/m
2, be the AGM dividing plate of domestic use and 5-10 times of other dividing plates, and supply is very inconvenient.So it is difficult that China adopts the import dividing plate to prepare colloid storage battery fully.
1993, the inventor changed the can colloidal electrolyte in order to improve the AGM battery with the AGM battery, made AGM colloid hybrid battery.Because electrolyte increases and the influence of gel to battery performance, this improved hybrid battery capacitance obviously increases, and deep discharge cycle life has also prolonged, and has promoted the development of China's electric bicycle industry.But this hybrid colloid storage battery perfusion colloid difficulty is separated because AGM, produces glue to the colloid percolation, and battery still can the seepage acid solution.Because battery structure does not change, in fact it be still lean solution formula battery, still has bulge and thermal runaway phenomenon.These shortcomings are seriously restricting the development of China's colloid storage battery industry
[1]
Summary of the invention
The objective of the invention is to improve battery structure, overcome perfusion colloid difficulty, eliminate the percolation of AGM to colloid, become the lean solution formula and be pregnant solution type, solve the low and expensive problem of external colloid storage battery specific energy simultaneously, a kind of method of being made colloid electrolyte lead-acid accumulator by the function admirable that is applicable to colloid storage battery, low-cost dividing plate is provided.

2Make gel.If adopt other to contain SiO
2Or the material of silicic acid, as Ludox, and produce colloid storage battery with rubber separator, also should belong to scope of the present invention.In addition, the content of gel (is amounted to into SiO in the colloid storage battery
2) what can not influence claim of the present invention.
Employed rubber separator is than other dividing plate low prices in the method for the present invention, prepared rubber separator battery, and it is deposited the glue amount and increases, and gel is full and uniform, no acid solution layering, the battery no leakage, battery cycle life is long, no thermal runaway.
Embodiment
Embodiment 1
Except AGM, the present invention has selected polyethylene (PE) dividing plate, 10g modification dividing plate, rubber separator to make the colloid storage battery test, and makes comparisons with the polyester coating phenolic resins dividing plate of DARAMIC.Here the rubber separator of usefulness is by natural rubber and SiO
2Reach sulphur and make through sulfuration, or natural rubber and SiO
2Make through electron radiation is crosslinked, its surface is a corrugated, helps pouring into colloid.Its resistivity≤0.003 Ω/dm
2, porosity is about 60%.Rubber separator mechanical strength height can stop antimony to shift between both positive and negative polarity, prevents dendrite short circuit, can make long life accumulator
[2]The 10g modification dividing plate here adds the diatomite modification in polyethylene.
The concrete preparation method of 4 test cells is as follows:
1. grid is the Pb-Ca alloy, and degree of oxidation of lead powder is 76%.
2. behind coated plate, curing drying, burst brush sheet, weld utmost point group.
3. insert different dividing plates, welding once more among the utmost point group.For the ease of operation, battery is uncovered
4. encapsulating charges.The prescription of colloid is the gas phase SiO that adds 3.0% weight in the sulfuric acid of proportion 1.28
2With a spot ofly help gel, the agent of lengthening the life, after strong agitation, directly pour in the battery and (need not vacuumize).Every single lattice battery pours into about 400ml colloid.After changing into according to a conventional method, survey battery 5A discharge time, its preceding 5 test capacity see Table 1.
Table 1, different dividing plate 12V, 40Ah colloid storage battery 5A discharge time
Because Pb-Ca alloy pole plate causes battery capacity early ageing, above-mentioned 5A presents significantly downward trend one by one discharge time, and it is no exception that polyester applies the phenolic resins dividing plate.The colloid storage battery capacity that rubber separator is made is comparatively stable, and a little more than polyester dividing plate battery.From the feature of long life that has of rubber separator, its price is also cheaply a lot of than polyester dividing plate.Therefore, rubber separator can be used as the dividing plate of colloid storage battery.
