Abstract
The electrolyte of macromolecule nanometer polymer used in lead acid storage battery and its preparation method were related in this invention. It relates the area of lead acid storage battery. According the weight ratio, the electrolyte is mainly made up of the raw materials as following: ligand agent 0.1-1.5%, complexing agent 2.5-4%, catalytic agent 0.01-0.5%, stabilizing agent 2.3-3.8%, conditioning agent 0.1- 0.5%, antifoam agent 0.01-0.5%, sulfuric acid 36-45%, the others is water. It is characterized in that the content of silicon dioxide is low, the dosage is little and the cost is also low. And in that a steady colloid can be formed in the electrolyte which can elongate the gelatum time. Used in the minitype encapsulation lead acid storage battery, the capacity can increase greatly, the operational life can be elongated and the low temperature resistance can also be enhanced. The gel in the electrolyte can avoid the overflow of acid liquor. Otherwise, the electrolyte also has the merits of little inherent resistance, high capacity, longevity and good thixotropy and so on.
Description
Technical field
The present invention relates to the lead acid cell field.
Background technology
At present, colloidal electrolyte in the colloid battery that uses can roughly be divided into silicon sol system with silica-based, each molecule in the colloid that existing compound method obtains is independently, and just mixing does not physically embody colloidal character fully.Small sealed lead-acid battery is with its stable performance, advantage such as inexpensive, non-maintaining and obtained widespread use on electric vehicle in recent years.But along with the increase of people's environmental consciousness and the formation of various countries' green barrier, environmental problem is outstanding all the more.Do you how can satisfy people's demand and reduce environmental pollution again as far as possible? pollution in lead acid cell can be divided into the 3 bulks--three wastes of the three wastes of making----early stage, the acid pollution the when user uses, recycling substantially.First and the 3rd could both focus on, just second suitable dispersion, bad processing! Adopt colloidal electrolyte can prolong greatly store battery work-ing life, avoid the discharge of acid mist, but traditional colloidal electrolyte gel time is short, poor permeability, and wherein contained element silicon can make accumulator internal resistance increase, and charge-discharge performance descends, and loss increases.
Summary of the invention
The object of the invention is to provide a kind of high-molecular nano polymer electrolyte for lead-acid battery of avoiding the overflowing of acid solution, long service life.
The present invention is mainly mixed by each raw material of forming by following weight percent and forms: coordination agent 0.1～1.5%, complexing agent 2.5～4%, catalyzer 0.01～0.5%, stablizer 2.3～3.8%, conditioning agent 0.1～0.5%, defoamer 0.01～0.5%, sulfuric acid 36～45%, water surplus.
The present invention carries out complexing with coordination agent and larger molecular organics under the effect of catalyzer, further hinge forms the stable gel body under the effect at electrical forces in the time of in the middle of adding battery.Advantage is: dioxide-containing silica is low, and consumption is few, and cost is low, can form the colloid of stable homogeneous in electrolytic solution, and gel time is long, is used for small sealed lead-acid battery and can significantly improves cell container, increases the service life, and resistance to low temperature is superior.The present invention forms gel and avoids overflowing of acid solution in battery, it also has advantages such as internal resistance is little, capacity is high, the life-span is long, thixotropic property is good simultaneously.In addition, the low-temperature performance of the lead acid cell that the present invention makes is especially remarkable, is fit to the all-round popularization in south, northern market.
As preferred version of the present invention: coordination agent 0.5～1%, complexing agent 2.6～3.4%, catalyzer 0.01～0.1%, stablizer 2.5～3.5%, conditioning agent 0.1～0.2%, defoamer 0.01～0.1%, sulfuric acid 36～45%, water surplus.

Stablizer is Lithium Sulphate or alkali, the salt that contains lithium ion.
Defoamer is glycerine polyoxyethylene polyoxypropylene ether (GPE) or tributyl phosphate (TBP).
Conditioning agent is sodium hydroxide (NaOH), potassium hydroxide (KOH) or yellow soda ash (Na
2CO
3).
Coordination agent is that particle diameter is the nano fumed silica (SiO of 8～15nm
2).
The catalyzer agent is sodium amide (NaNH
2) or sodium Metal 99.5 (Na).
The present invention also provides a kind of compound method for preparing the high-molecular nano polymer electrolyte of above-mentioned lead acid cell.
That is, respectively coordination agent, complexing agent, catalyzer, defoamer, conditioning agent are formed in proportion the A component, stablizer, sulfuric acid and water surplus are formed the B component in proportion, then, mix A component and B component.
In addition, the pH value of A component is 9～12.
The inventive method technology is simple, conveniently manufactures, and product stability is good.
