Abstract

The hydrochloric acid and dilute sulfuric acid are mixed to obtain a mixture, and the additive and solidifying agent are mixed to obtain another mixture, then both two mixtures are mixed together so as to obtain the invented electrolyte for accumulator. After having been stirred and emulsified said electrolyte can be stored for a long period up to a year, and the accumulator made up by using said electrolyte does not automatically discharge, and within a year it has no need of adding electrolyte or regulating density of electrolyte, only has need of adding a small quantity of distilled water, and can be used for a long period. Its service life is 1-3 times that of general accumulator, and its price is identical to that of general accumulator.

Description

The high-energy battery of electrolyte and manufacturing process thereof and manufacturing thereof

The present invention relates to a kind of electrolyte and manufacturing process thereof with and the high-energy battery made.

At present; the storage battery that generally uses is lead acid accumulator; the electrolyte of its use all is that density is 1.28 dilute sulfuric acid; the sulfur dioxide acid mist environmental pollution that this electrolyte produces is very big; its pollution level is also bigger than vehicle exhaust, is unfavorable for environmental protection, and this kind electrolyte also can corrode and wash away pole plate in addition; cause pole plate to damage in early days and the pole plate layer on active material PbO ₂Come off; shortened useful life,, adopted negative plate to Duo one arrangement usually than positive plate in order to protect positive plate; the capacity of the distribution mode restriction storage battery of this pole plate; must maintaining, the liquid feeding that changes according to the season, adjust proportion and replenish electricity, the power-on and power-off potential difference is big, storage battery surface sulfuric acid liquid spills fouling and discharges automatically; and storage short constantly (needing to replenish in 28 days); to harsh weather, environment (mountain area, desert) conformability is poor, and low temperature is born 18 ℃ of starting vehicle difficulties.

Therefore, purpose of the present invention is exactly at above-mentioned situation, provides a kind of environmental pollution few, the electrolyte of long service life.

Another object of the present invention just provides this electrolytical manufacturing process.

The 3rd purpose of the present invention is electrolytical soft solid high-energy battery with regard to the electrolyte that provides a kind of the present invention of utilization and make.

Electrolyte of the present invention is made (volume is a percentage) by following raw material.

Phosphoric acid 0.6-1

Additive 0.55-0.6

Dilute sulfuric acid 51-52

Curing agent 47-48

Described phosphoric acid meets GB1282-77; Described additive is to be formed through the pure water dilution by industrial glycerine, and the density after the dilution is 1.34-1.36; Described dilute sulfuric acid is to be formed through the pure water dilution by the special-purpose sulfuric acid of storage battery, and the density after the dilution is 1.56-1.57; Described curing agent be by the sodium silicate of conformance with standard HGB3111-59 with the pure water dilute filtration of heating, and form by ion-exchange water purifying apparatus.The density of this curing agent is 1.055-1.06.Above used its purity requirement of pure water more than 350,000 ohm.

Above-mentioned electrolytical manufacturing process is as follows:

(1), phosphoric acid is poured into made mixture A in the dilute sulfuric acid;

(2), additive is poured into made mixture B in the curing agent;

(3), mixture B is poured into make mixture A+B among the mixture A and be electrolyte of the present invention.

This mixture A+B will be frozen into the soft solid state automatically after 20-30 minute, therefore must could inject when this mixture A+B is liquid state when making storage battery.Can long preservation prepare against use at any time in order to make this electrolyte, can will place after the mixture A+B stirring and emulsifying in the bin, just become the liquid electrolyte that can use at any time after slaking 6--10 days, the liquid electrolyte that this is standby, in case be injected into the storage battery the inside, will be frozen into the soft solid state after 4 hours.

High-energy battery of the present invention, the liquefied mixture A+B that the electrolyte of employing is made for the present invention, this liquefied mixture A+B can be frozen into soft solid automatically after injecting accumulator 20-30 minute, become the soft solid electrolyte.The distribution of its pole plate is that positive plate is many, and negative plate Shaozheng pole plate is Duoed one than negative plate.Described positive plate is to scribble one deck by SnO, Bi at common polar board surface ₂O ₃And the lead plaster made in 12: 12: 100 ratio of lead powder.Owing to be injected into electrolyte mixture A+B in the storage battery, can be frozen into the soft solid state automatically after half an hour, thereby avoided vehicle erosion corrosion to pole plate in the vibration processes that frequently jolts to make PbO ₂Come off in advance, also reduce simultaneously storage battery and when big load uses, produce buckling phenomenon and short-circuit between plates fault, long service life, under normal circumstances its useful life is longer more than one times than the useful life of the storage battery of liquid electrolyte, can reach 3-4, in addition because electrolyte is that soft solid does not have excessive phenomenon, free from environmental pollution, in addition behind this electrolyte expendable, in use need not replenish electrolyte again and adjust electrolytical density, need only can use by auxiliary point distilled water, need not boost charge again in 1 year, as the charging after deposit need not, can self-discharge.Resting period, can be for 1 year.This battery capacity is big, and adaptive capacity to environment is strong, not influenced by temperature, and its temperature that is suitable for is-40 ℃-+65 ℃.Solid electrolyte can not dissolve under+65 ℃ environment.This electrolyte, split can also cruising 30-100 kilometer for storage battery in vehicle traveling process.

Below in conjunction with accompanying drawing electrolyte production technology of the present invention is described further

Fig. 1, electrolyte technological process of production figure.

(1), phosphoric acid is poured into made mixture A in the dilute sulfuric acid;

(2), additive is poured into made mixture B in the curing agent;
