Abstract
The invention relates to an electrolyte of lead-acid battery and preparation method thereof. The electrolyte comprises the following raw materials by parts by weight: 20-40 parts of deionized water, 62-68 parts of dilute sulphuric acid, 1.5-2.5 parts of nano aerosol and 2-2.5 parts of electrolyte active agent; wherein the electrolyte active agent is formed by analytically pure potassium sulphate, zinc sulphate, ammonium sulphate, magnesium sulphate, aluminium sulphate, sodium sulphate, cobalt sulphate, aluminium phosphate and lithium iodide in certain ratio; and multiple micro elements are added into the electrolyte, so that the nano silicon oxide particles have favourable dispersity, the prepared electrolyte has no sedimentation, flocculation or layering for a long time, and meantime service life and environmental performance of battery can be effectively improved.
Description
Technical field
The present invention relates to a kind of electrolyte and preparation method thereof, electrolyte of especially a kind of lead acid accumulator and preparation method thereof.
Background technology
At present; In lead acid accumulator production, generally use wherein a kind of main preparation method of colloidal electrolyte to be gelatinizing agent with the nano fumed silica powder; Because the nano fumed silica powder has good thixotropy, flowability, thickening property, is applied in the lead acid accumulator, can improve the electrical property of lead acid accumulator; Increase the service life, so nano fumed silica is improved the preferred material of battery liquid function in recent years by extensive conduct.But because nano silicon particle diameter small specific surface is long-pending big, absorption produces and reunites and sedimentation very easily each other, when being applied in the battery liquid, can produce can and the result of use that the sedimentation layering influences storage battery at short notice because of dispersion that can not be good.And various trace elements joins in the battery liquid, can prevent the accumulator plate sulfuration, and can effectively reduce the volatilization of battery liquid, not only improves battery capacity and useful life, has also promoted the environmental-protecting performance of storage battery.
Summary of the invention
The technical issues that need to address of the present invention provide electrolyte prescription of a kind of lead acid accumulator and preparation method thereof; Can make the nano silicon grain of adding have good dispersiveness; The electrolyte long period of preparation does not have sedimentation, do not have flocculation and does not have layering, and the contained multiple minor metallic element of electrolyte activating agent can effectively improve and promote storage battery use and environmental-protecting performance simultaneously.
Technical scheme of the present invention is electrolyte of a kind of lead acid accumulator and preparation method thereof; Comprise following raw materials in weight portion: deionized water 20-40, dilution heat of sulfuric acid 62-68, nanoscale aerosil 1.5-2.5, electrolyte activating agent 2-2.5 form; Wherein deionized water resistance is not less than 16 megaohms; Dilution heat of sulfuric acid density is 1.5-1.6, and the particle diameter of nanoscale aerosil is 20-40nm, and specific area is 300m
2More than/the g, electrolyte activating agent each component and ratio thereof are: deionized water 1000, potassium sulfate 20, zinc sulfate 20, ammonium sulfate 13 magnesium sulfate 25, aluminum sulfate 30, sodium sulphate 15, cobaltous sulfate 13, aluminum phosphate 25, lithium iodide 5.Carry out the first step by the following order step: be dissolved in potassium sulfate, zinc sulfate, ammonium sulfate, magnesium sulfate, aluminum sulfate, sodium sulphate, cobaltous sulfate, aluminum phosphate, lithium iodide in the deionized water, mix, make the electrolyte activating agent; Second step: mix deionized water, nanoscale aerosil, electrolyte activating agent, dilution heat of sulfuric acid and make solution and be cooled to≤35 ℃; The 3rd step: disperse disposable completion electrolyte manufacturing process with carrying out high speed shear in the above-mentioned solution immigration titanium alloy colloid mill.In the test that is equal to; Add potassium sulfate, zinc sulfate, ammonium sulfate in the electrolyte activating agent and will increase 15-20% than its battery capacity of electrolyte activating agent, the battery cycle life that do not add potassium sulfate, zinc sulfate, ammonium sulfate; This method has used new active agent formulation and high speed shear to disperse technology of preparing simultaneously; It is that the time is controlled at 10-20min with titanium alloy colloid mill high speed dispersion that high speed shear is disperseed technology of preparing, and linear velocity is controlled at 18-25m/s during dispersion.
Advantage applies of the present invention makes the excellent properties of nano silicon such as good thixotropy, flowability, thickening property be able to abundant release at the good dispersion of electrolyte; Sedimentation, flocculation and lamination do not take place in the good stability of electrolyte, the electrolyte that produces for a long time; Can alleviate the corrosion of grid and suppress dehydration, have good high current charge-discharge and the little effect of storage battery self discharge, electrolyte does not have acid mist and produces, and is environmental.
