Abstract
The invention relates to a polymer colloid electrolyte for a lead-acid storage battery, belonging to the field of chemical power supplies, in particular to the technical field of production of the polymer colloid electrolyte for the lead-acid storage battery. The polymer colloid electrolyte is mainly prepared from sulfuric acid, polymer gel, additive and deionized water through mixing according to a certain proportion, wherein the polymer colloid is prepared form polyvinyl alcohol colloid and potassium polyacrylate through mixing and processing according to a certain proportion; and the additive is a carbon nano-tube and stannous sulfate. The storage battery poured by using colloidal electrolyte has excellent starting property and stable discharge performance, improves the low-temperature discharge performance and the phenomenon of active material shedding because of vibration, and solves the problems of short storage period and short circulation service life.
Description
Technical field
The invention belongs to field of chemical power source, relate to a kind of electrolytical production technical field of polymer colloid that can be used for lead acid accumulator.
Background technology
Lead acid accumulator is with a long history, and colloid storage battery generally adopts gas phase SiO at present
2For matrix prepares colloidal electrolyte.Gas phase SiO
2Not only cost an arm and a leg, and the colloidal electrolyte of preparation exists SiO for a long time
2Content is low, freeze thaw stability is low, consolidate sour ability, gel strength problem of unstable.Produced the problem that the battery shock resistance is poor, initial capacity is low, colloid chaps aquation, battery leakage thereupon.
Summary of the invention
The object of the present invention is to provide electrolytical prescription of a kind of polymer colloid and preparation method to replace SiO
2Colloidal electrolyte is to address the above problem.
Polymer colloid electrolyte of the present invention is mixed by sulfuric acid, high-molecular gel body, additive and deionized water, and their quality is respectively 35～40%, 6～8%, 0.01～0.15% of configuration gross mass, and all the other are deionized water.
Described polymer colloid electrolyte gel body is mixed according to mass ratio by polyvinyl alcohol and polyacrylic acid potassium and is dissolved in water and makes colloidal sol at 10: 1, makes through shearing through high speed machine after 4 freeze thawing then again.
Described additive is the mixture of CNT (carbon nano-tube) and stannous sulfate, and the mass ratio of CNT (carbon nano-tube) and stannous sulfate is 1: 5.
The present invention is by the colloidal electrolyte good fluidity of high speed shear preparation, be poured into storage battery after, under effect of electric field, become semisolid by fluid, form the gel of stable performance.The gel particle size has abundant fluid course at nanoscale, has reduced the contraction of active material when low temperature, has improved low temperature performance.Polyvinyl alcohol can with metal ion-chelant, increase active material utilization.The interpolation of nano carbon tube improves electrolytic conductivity in metal ion in the polyacrylic acid potassium structure and the electrolyte, reduces the internal resistance of cell.And gel electrolyte is in gel state, and good springiness can delay the vibrations that battery is subjected to well.Semi-solid electrolyte water absorption is strong simultaneously, has avoided the generation of battery leakage phenomenon.Lead acid accumulator discharge performance with the polymer colloid electrolyte perfusion is stable, and startability is good, and deep discharge cycle life is better than traditional liquid electrolyte lead acid accumulator.
