Abstract
The colloidal electrolyte that a kind of lead acid accumulator is used is the solution formation by sulfuric acid, Ludox, alkali metal (Li, Na, K) hydroxide.Earlier with alkali hydroxide soln and Ludox mixing, slowly add sulfuric acid then and gently stir evenly and form during preparation.Can once pour into, discharge is used after the initial charge, secondary pouring, also can once pour into the back and directly use, capacitance is all above existing request of national standard.
Description
The present invention relates to colloidal electrolyte and manufacture method thereof that lead-acid battery is used.
Electrolytic liquid sulfuric acid exists shortcoming such as easy leakage acid solution, acid solution volatilization and causes etching apparatus and human body in the lead-sour battery, is particularly tilting and is shaking, rocks and use its harm particularly outstanding under the condition.People createed colloidal electrolyte in the last few years, had solved this class problem preferably.Particularly people's such as Susi Susanti invention (CN90102353.1) has been illustrated Ludox content (with SiO
2And＞9.9% unfavorable factor meter)＜3%; Prove the combined influence of Ludox and two kinds of concentration of sulfuric acid again; In colloidal electrolyte, add aluminium hydroxide in order to improve capacitance.Made colloidal electrolyte has solved the aquation that forefathers exist, be full of cracks in colloidal electrolyte, gel is fast and cause the shortcoming that perfusion is difficult, cost is high, and forefathers' colloidal electrolyte capacity (is 100% with the electrolyte sulfuric acid battery capacity) is brought up to 86.0～91.6% from about 50～60% or 80%.
The purpose of this invention is to provide the more special colloidal electrolyte of a kind of performance: capacitance surpasses electrolyte sulfuric acid; Also do not have solution leakage in 90～180 ° of uses of long-term inclination, can use without charging after the electrolyte perfusion.Another object of the present invention provides the more easy method of this electrolyte of preparation, makes its cost more cheap.
Colloidal electrolyte provided by the invention is made up of sulfuric acid, Ludox and small amount of alkali metal hydroxides and water, and alkali metal hydroxide wherein mainly is the hydroxide of Li, Na, K.Sulfuric acid proportion is 1.40～1.60; Thickness of silica gel is that 8～10%(is with SiO
2Meter), granularity is 3～5 * 10
-8M, no CL; And the concentration of alkali hydroxide soln is 1～5%, and the composition of colloidal electrolyte (volume) is:
Sulfuric acid 1000.00
Silicon sol solution 500.00～1000.00
Alkali hydroxide soln 0.30～0.70
During preparation be in nonmetallic vessel, solution with alkali metal hydroxide under stirring is added in the silicon sol solution, the sulfuric acid that will prepare and be cooled to room temperature then adds, be fed in the storage battery after the light stirring evenly, liquid level is higher than filter screen 3～5mm, is supplemented to former liquid level when liquid level descends to some extent after static a few hours.Then need not carry out conventional initial charge if do not drop into the discharge use in 48 hours, being supplemented to colloid surface with deionized water or distilled water frequently in the initial charge has obvious ponding.Adding colloidal electrolyte (i.e. perfusion for the second time) after the initial charge again to being higher than filter screen 20～25mm, can come into operation later at any time.If when discharge is used in back 48 hours of perfusion, can drop into discharge after 4～12 hours immediately and use as long as leave standstill, do not need initial charge.If carry out second perfusion then for the second time the electrolytic condenser of perfusion pour into used electrolyte for the first time wherein Ludox content be high slightly, the proportion of sulfuric acid also needs big.Electrolyte solution its proportion after mixing is 1.28 ± 0.01, meets the requirement of a plumbous acid accumulator, 0.5～1.0 hour at normal temperatures formation colloid; And its gel time prolongs 1～2 times after pouring into battery.The battery capacity of being irritated by this electrolyte dress is big, and the usefulness height is through standard testing repeatedly with on probationly on ship, car all obtain goodish result.
The present invention compares its advantage with background technology: (1) main electricity function index height, and above the regulation of China's national standard (GB5008.1-85).1. the storage battery with colloidal electrolyte perfusion of the present invention discharges its capacity first more than 125%, even its capacity that discharges for the third time is also more than 110%; 2. discharge time lasting, can reach more than the 24h, and general colloid battery discharge time is all below 20h; 3. starting capability is strong, can be with the 3C20A discharge 60S of regulation in-18 ℃ of environment, and single lattice average voltage is 1.5V.(2) there are not leakage, nothing volatilization, pollution-free, particularly because twice perfusion electrolyte difference, its viscosity difference, little in pole plate group internal resistance, and on pole plate top thickness is arranged is the gel electrolyte of 15～25mm, battery is in for a long time with ground and is 90 degree even 180 degree work and ne-leakages, and the upper strata outer casing rupture also can be worked as usual; (3) the electrolyte particularly of the present invention use of can under the situation of not carrying out initial charge, can directly discharging, and have the excellent properties that surpasses existing electrolytical capacitance equally, can save electric energy and man-hour in a large number; (4) used alkali metal hydroxide in the prescription, play very important function on enhancing electrical property and capacitance, method for making is simple, with low cost in addition.
Example 1
The colloidal electrolyte preparation, raw material specification is:
Sulfuric acid; Be made into proportion by the concentrated sulfuric acid and deionized water and be respectively 1.42 and 1.56 two kinds.
Silicon sol solution: concentration is that 8%(is with SiO
2Meter), granularity is 3～5 * 10
-8M, no chlorine root, formulated by commercially available Ludox and deionized water.
Potassium hydroxide solution: concentration is 5%, and is formulated by reagent product and deionized water.
Prepare two kinds of electrolyte, its each raw material consumption (volume rises) is as follows:
The molten KOH solution of sulfuric acid Ludox
Ⅰ 20(D:1.42) 10 0.005
Ⅱ 10(D:1.56) 10 0.005
During preparation in Plastic Drum with silicon sol solution and potassium hydroxide solution stirring and evenly mixing, slowly sulfuric acid is added then, gently stir well even.Earlier the electrolyte I is poured in the 6-Q-195 battery to being higher than filter screen 3～5mm, leave standstill, added I one time in per 2 hours, carry out conventional initial charge after 6 hours, added deionized water every 2～3 hours, rate of water make-up is looked the colloidal electrolyte surface has obvious ponding to be advisable.The II electrolyte poured into battery in 3 hours after the initial charge, liquid level is higher than filter screen 20～25mm.The discharge test capacitance is 110%.
Example 2
The colloidal electrolyte preparation just replaces KOH with LiOH as example 1.Battery carries out capacity test after I perfusion-initial charge-II perfusion, three times discharge capacity is respectively 130%, 135%, 140%.
Example 3
Preparation colloidal electrolyte raw material consumption (liter) is:
Sulfuric acid (D: 1.50) 10
(10% with SiO for silicon sol solution
2Meter, granularity is 3～5/10
