Embodiment 1

[0058] The battery that is directly converted from chemical to liquefaction to electrolytic solution provided in this embodiment specifically includes the following steps:

[0059] 1). Preparation of SiO containing ultrafine particles 2 The electrolyte stock solution:

[0060] a. Weigh 14% of the total volume containing 34.95% SiO 2 Na 2 OSiO 2 , Where SiO 2 The particle size is 32nm;

[0061] Weigh 12% of the total volume of Na 2 SO 4 ;

[0062] Weigh 9.95% of the total volume of Na 2 CO 3 ;

[0063] Weigh 0.4% of the total volume of polyaminosiloxane;

[0064] Weigh 0.015% of the total volume of poly-3-chlorobutene;

[0065] The balance is distilled water; the above raw materials are all chemically pure raw materials purchased on the market.

[0066] Specific preparation process:

[0067] First, the above-mentioned good Na 2 OSiO 2 Put it into a high-pressure container, add Na in turn 2 SO 4 , Na 2 CO 3 , Poly3-chlorobutene, polyaminosiloxane and distilled water, mix well and re...

Embodiment 2

[0083] The battery produced by directly changing from chemical to liquefaction to electrolytic solution provided in this embodiment includes:

[0084] 1. Take 15 parts by volume of the electrolytic stock solution of ultrafine particles prepared in Example 1, and add 32 parts by volume of deionized water, and stir for 10 minutes. Use a hydrometer to measure the specific gravity of the diluted solution to be 0.89 to 1.09, and its pH value Is 7.5;

[0085] 2. Take the diluted electrolytic stock solution prepared in step 1 and add sulfuric acid, first adjust the specific gravity of sulfuric acid to 1.40, and then mix and stir with the volume ratio of sulfuric acid: diluted electrolytic stock solution of 4:1 to make the specific gravity reach 1.28;

[0086] 3. Put the mixed solution prepared in step 2 into a high-voltage electric field above 600V for polarization, molecular rearrangement makes the ion movement channel unobstructed and the internal resistance is extremely small. Said is ...

Embodiment 3

[0091] The steps in this embodiment are the same as those in embodiment 1, except that the specific conditions are different, and the differences are as follows:

[0092] 1) Ultra-fine particles of SiO 2 The preparation of the original electrolyte solution: using commercially available chemically pure, containing 34.95% SiO 2 Na 2 OSiO 2 , Where SiO 2 The particle size is 50nm, weighing 16% of the total volume of Na 2 OSiO 2 Material; buy Na in the market 2 SO 4 Accounted for 10.5%;, chemically pure Na purchased on the market 2 CO 3 ; Weigh 11% of the total volume of chemically pure polyaminosiloxane purchased on the market; weigh 0.8% of the total volume of chemically pure poly-3-chlorobutene 0.02%; the balance is Distilled water

[0093] 2). Take step 1) ultra-fine particles of SiO 2 15 parts by volume of the electrolytic stock solution, and add 59.5 parts by volume of distilled water, stir for 10 minutes, use a hydrometer to measure 0.89 to 1.09, and its pH value is 9;

Abstract

The related preparation method for comprises: first preparing the electrolyte, adding 30-60 times water to every one share electrolyte for dilution, and adding inorganic acid as 4:1 with respect to the diluted liquid; polarizing the mixed liquid in electronic field over 600V to obtain the polarized liquid, stirring in a stirrer with 100-300r / min speed for 3-10min, splitting out the liquid with dc pump, canning in the accumulator shell directly, and sealing well. The product has charge acceptance as 2. 6 times to the lead-acid one, and over three times to common colloid battery. This invention is simple and produces little pollution.

Description

Technical field [0001] The invention relates to a method for manufacturing a storage battery, in particular to a storage battery that is directly converted from chemical to liquefaction to electrolyte and a preparation method thereof. Background technique [0002] Electrolyte is an important part of battery manufacturing. When the shell, plate, and separator are fixed, the performance of the battery depends on the electrolyte. Generally, in the process of manufacturing lead-acid batteries, sulfuric acid solution is used as the electrolyte. On the one hand, a large amount of corrosive white smoke is produced when sulfuric acid is mixed with water; on the other hand, a large amount of corrosive is also produced when the battery is sulfated. This corrosive white smoke causes serious harm to people and the environment. On the other hand, the process of manufacturing lead-acid batteries is complicated and labor-intensive. People have been trying to find an environmentally friendly ele...
