Abstract
The present invention relates to an accumulator electrolyte with the advantages of no environmental pollution, long service life and long term storage property, and a preparation technique for the accumulator electrolyte. The accumulator electrolyte is prepared from main raw materials of phosphoric acid, an additive, diluted sulfuric acid and a solidifying agent, and prepared by that phosphoric acid is mixed with diluted sulfuric acid, an additive is mixed with a solidifying agent, and two mixtures are mixed. The electrolyte after being stirred and emulsified can be stored for a long term as long as a year. An accumulator made from the electrolyte can not automatically generate electric discharge, is free from adding the electrolyte or adjusting the density of the electrolyte in a year, and can be used for a long term only by adding a little distilled water. The service life of the accumulator is three times longer than that of a common accumulator, and the price of the accumulator is equivalent to that of the common accumulator.
Description
Technical field: the present invention relates to a kind of storage battery.
Technical background: at present, the storage battery that generally uses is lead acid accumulator, and its electrolyte that uses all is that density is 1.28g/cm
3Dilute 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; be unfavorable for environmental protection; 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 the storage time short (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.
Summary of the invention: purpose of the present invention is exactly at above-mentioned situation, provides a kind of environmental pollution few, the storage battery of long service life.The used electrolyte of storage battery of the present invention is made (consumption is a percent by volume) 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 1.34-1.36g/cm
3Described 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 1.56-1.57g/cm
3Described 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 1.055-1.06g/cm
3. top its purity requirement of used pure water is more than 350,000 ohm.Above-mentioned electrolytical manufacturing process is as follows: (1), phosphoric acid poured into make 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 the injecting accumulator 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 is few, and positive 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 lead powder is the lead plaster that 12: 12: 100 ratio is made by weight.Owing to be injected into the electrolyte mixture A+B in the storage battery, can be frozen into the soft solid state automatically after half an hour, thereby have 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 boost charge again in a 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 can not dissolved for solid electrolyte under-40 ℃ one+65 ℃ the environment.This electrolyte, split can also cruising 30-100 kilometer for storage battery in vehicle traveling process.
Description of drawings: Fig. 1, electrolyte technological process of production figure.
Embodiment: (1), phosphoric acid poured into make 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 this mixture A+B among the mixture A and be electrolyte of the present invention.
