Embodiment Construction

[0019] With reference to accompanying drawing, the present invention comprises the following steps:

[0020] 1. Configure the electrolytic stock solution. The composition of the electrolytic stock solution is:

[0021] A. Contains 31-37.9% pure silicon dioxide (SiO 2 ) of sodium silicate (Na 2 OSoO 2 ) 12~15%;

[0022] B. Sodium sulfate (Na 2 SO 4 ) 11~16%;

[0023] C. Sodium carbonate (Na 2 CO 3 )8.87~10%;

[0024] D. Poly-3-chlorobutene 0.014~0.028%;

[0025] E. Polyaminosiloxane 0.38~1.18%;

[0026] F. The balance is water. The above is volume percentage;

[0027] 2. Dilute the prepared electrolytic stock solution and water with a volume ratio of 1:30-50 and add water. The specific gravity of the diluted liquid is 0.87-1.1 g / cm 3 , the pH value is 8.5-9.1;

[0028] 3. Adjust the specific gravity of the inorganic acid to 1.356-1 g / cm 3 , mixing and stirring the diluted liquid and the inorganic acid at a volume ratio of 3.8 to 4:1;

[0029] 4. Place the mixed ...

Abstract

The invention provides an electrolyte used for manufacturing a sodium silicate storage battery. The electrolyte comprises 12-15% of sodium silicate (Na2OSiO2), 11-16% of sodium sulfate, 9-10% of sodium carbonate, 0.014-0.028% of poly(3-chlorobutene), 0.38-1.18% of polyaminosiloxane, and the balance water, wherein the sodium silicate contains 31-37.9% of silica (SiO2) particles, and above percentages are volume percents. The invention also provides a preparation method of the electrolyte of the sodium silicate storage battery. The preparation method comprises the following steps: weighing above materials according to above formula, putting the materials into a high pressure container, heating the container to the temperature in the high pressure container of 100-400DEG C and the pressure in the high pressure container of 2.85-6.17MPa, maintaining the temperature and the pressure for 21-31h, and cooling to room temperature to obtain the clarified liquid electrolyte containing granulated nano-scale SiO2. According to the preparation method, severe acid mist pollution in the making of traditional electrolytes is overcome, so there are no pollution damages to humans and the environment, and problems of hydrogen evolution flash-explosion, acid mist corrosion and the like are solved; and used electrolytes are acidic composite fertilizers, have no pollution and are extremely easy to process, and battery plates can also be recycled.

Description

technical field [0001] The invention relates to the field of accumulators, in particular to a method for manufacturing an accumulator. Background technique [0002] In 1859, French engineer Plante invented the lead-acid battery, which brought profound changes to the development of human productivity and social progress. However, the pollution caused by lead-acid batteries in the process of manufacture and use and their wastes also brings serious harm to human beings. It is especially worth noting that a large proportion of lead-acid batteries in my country are still old-fashioned open batteries, which are prone to gas and acid during use. A certain amount of lead and sulfuric acid are released into nature every year. According to statistics, a rotten small lead-acid battery can make one square meter of land useless. Traditional lead-acid batteries have become a serious source of pollution and need to be improved urgently. [0003] In recent years, with the progress of in...
