Description

Low acid, low sodium, high-energy silicon ability electrolyte and manufacturing approach thereof

Technical field

The present invention relates to a kind of low acid, low sodium, high-octane silicon ability electrolyte and manufacturing approach thereof.

Background technology

In recent years, the sealed lead-acid accumulator free from maintenance technical development is rapid, and obtains extensive use.But deficiency such as existing sealed lead-acid accumulator free from maintenance technology exists, and internal resistance is big, capacity is low, discharge performance decline, thermal runaway, battery charge dilatancy, cycle life have only about 300 times.

Summary of the invention

The objective of the invention is deficiency, provide a kind of low acid, low sodium, high-octane silicon can electrolyte to existing battery, this electrolyte is poured into storage battery after, chemical synthesis technology changes into and can process valve-regulated power accumulator by the AGM technology by plumbic acid.

Another object of the present invention is that the manufacturing approach of this low acid, low sodium, high-octane silicon ability electrolyte is provided.

For realizing first above-mentioned purpose: low acid provided by the invention, low sodium, high-octane silicon ability electrolyte, the composition material of by volume calculation electrolyte is following:

1, concentration is 30%, particle diameter is the Nano silica sol 4.5-5% of 10-20nm;

2, concentration is 10% metabisulfite solution 0.5-1%;

3, concentration is 10% oxygenation agent liquid 0.5%;

4, proportion is 1.4 sulfuric acid solution 50-55%;

5, through the pure water 38.5-44.5% after the filtration of quantum tube through ring.

For forming another above-mentioned purpose, the manufacturing approach of this electrolyte comprises the steps:

1, Ludox is added 3 times in the pure water of its volume, add simultaneously metabisulfite solution,

Oxygenation agent liquid is 2000 rev/mins through magnetic stirring apparatus with rotating speed and stirred 20-30 minute, forms the silicon complex liquid;

2, the silicon complex liquid with step 1 adds in the sulfuric acid, adds the pure water of residual volume simultaneously, is 2000 rev/mins through magnetic stirring apparatus with rotating speed and stirs 20-30 minute, after quantum tube through ring filtration treatment, produces the electrolyte of Ph value for 2-4 again.

After this electrolyte poured into storage battery, chemical synthesis technology changed into and can process valve-regulated power accumulator by the AGM technology by plumbic acid.Confirm that through repeatedly putting into practice the battery that this electrolysis is processed has the following advantages:

1, self discharge stream is little, and large current charge efficient is high, and the charging back resting period is long;

2, internal resistance is little, is fit to heavy-current discharge, and discharge steadily;

3, compare with the lead-acid battery of same capability, specific energy is big;

4, temperature be suitable for wide, in-40-50 ℃ scope, the normal use;

5, use has extended cycle life, and discharging and recharging number of times is more than 1 times of lead-acid battery

6, low-voltage, the low capacity discharge performance is good;

7, memoryless charging;

8, non-maintaining, no acid mist produces, and non-pollution discharge meets the requirement of energy-saving and environmental protection, efficient, storage battery.

Embodiment

Embodiment:

The composition material of by volume calculation electrolyte is following:

1, gets that concentration is 30%, particle diameter is the Nano silica sol 5% of 10-20nm;

2, getting concentration is 10% metabisulfite solution 0.5%;

3, getting concentration is 10% oxygenation agent liquid 0.5%;

4, getting proportion is 1.4 sulfuric acid solution 50%;

5, the pure water 44% of quantum tube through ring after filtering of learning from else's experience.

Manufacturing approach is following:

Step 1, with concentration be 30%, particle diameter is 10-20nm; The Nano silica sol that accounts for cumulative volume 5% is incorporated as 3 times of its volumes; Promptly account in the pure water of cumulative volume 15%; Metabisulfite solution and the concentration that to add concentration simultaneously be 10%, account for cumulative volume 0.5% is 10%, accounts for the oxygenation agent liquid of cumulative volume 0.5%, is 2000 rev/mins through magnetic stirring apparatus with rotating speed and stirs 20 minutes, forms the silicon complex liquid that accounts for cumulative volume 21%;

Step 2, the silicon complex liquid adding proportion that step 1 is obtained are 1.4, account in the sulfuric acid solution of cumulative volume 50%; Add residual volume simultaneously; Promptly. account for the pure water of cumulative volume 29%; Is 2000 rev/mins through magnetic stirring apparatus with rotating speed and stirred 30 minutes, again after quantum tube through ring filtration treatment, produce 100% cumulative volume, Ph value is the electrolyte of 2-4.

Wherein, the quantum tube through ring that the quantum device that uses in the making is produced for the technological Co., Ltd of German IAB bio-energy.Oxygenation agent liquid is the Lower Ordovician Series dolomitic limestone of " Li Zegang ring ", has negative ion-releasing function, is a kind of natural ore, and it is processed oxygenation agent liquid after levigate.

After the electrolyte of the foregoing description poured into storage battery, chemical synthesis technology changed into and can process valve-regulated power accumulator by the AGM technology by plumbic acid.

Fig. 1 has represented the discharge curve chart by the 12V17Ah power accumulator of this making,

It is 6A that Fig. 1 is illustrated in discharging current, and the situation of discharging 174 minutes is 6A * 174 minute=17Ah between its electric current is taken the opportunity.
