Abstract
The present invention is a kind of silica-gel accumulator and preparation method thereof.Its electrolyte contains: the phosphoric acid of 1%-3%, the ethyl alcohol of 0.5%-1.5%, the sulfuric acid that the silica solution of 47%-49% and the specific gravity of surplus are 1.530-1.600.Compared with prior art, the present invention colloidal electrolyte internal resistance is substantially reduced, and battery capacity increases, life due to using ethyl alcohol silica gel electrolyte.
Description
Technical field
The invention belongs to which chemical energy to be directly changed into the method and apparatus of electric energy, a kind of silica gel electric power storage is specifically said it is
Pond and preparation method thereof.
Background technique
Colloid storage battery with its acid nonleakage, battery life is long the features such as, be socially widely used, and with research
Deepen continuously, electrical property is gradually increased.Application No. is in 88106105.0 China's application for a patent for invention prospectus
The production method for describing a kind of silica-gel accumulator needing less maintenance, it is to joined 5/1000-30/ in colloidal electrolyte
The oxalic acid of phosphoric acid and 5/1000-15/1000 that 1000 content is 85%.The addition of phosphoric acid and oxalic acid, undoubtedly to raising battery
Electrical property play certain effect, but internal resistance, capacitance of battery etc. be not still very ideal.
Summary of the invention
The purpose of the present invention is new additive is added in the electrolyte of battery, with provide a kind of new electrolyte and
Its preparation method improves the performance of battery further.
The purpose of the present invention can be reached by following scheme: battery of the invention, and electrolyte is by silica gel, sulphur
Acid, phosphoric acid composition, are characterized by electrolyte and also contain ethyl alcohol, each ingredient concrete content are as follows: the phosphorus containing 1%-3%
Acid, the ethyl alcohol containing 0.5%-1.5%, the silica solution containing 47%-49% are 1.530-1.600's containing the specific gravity having a margin
Sulfuric acid.
The silica solution that the present invention uses is that sodium metasilicate is diluted to specific gravity with distilled water is between 1.030-1.050, normal
Temperature lower purification 30-36 hours, make its silica (SiO2) content be 4.5%-5.5% sodium hydride (Na2O) content is 2.5%-
3%.
Specific embodiment
Below with reference to one embodiment, a kind of silica-gel accumulator provided by the invention and preparation method thereof is carried out detailed
Explanation.
Embodiment
The preparation method of electrolyte of the present invention are as follows: 0.5-1.5 parts of ethyl alcohol and 1-3 parts of phosphoric acid are added to 47-50 parts of specific gravity
To be stirred evenly in the sulfuric acid of 1.530-1.600 at normal temperature, the sulfuric acid solution and each portion of silicon sol solution are taken, mixing is simultaneously
It stirs evenly, it can injecting accumulator.
Compared with prior art, the present invention one makes the colloid solidification time extend 7 minutes or so since ethyl alcohol is added, this
Sample increases hair processing operation time, the second is colloid shrinking percentage reduces, sulfuric acid content increases, and battery capacity increases, in electrolyte
Resistance is substantially reduced, life.Sample is through detecting, first start ability: 1.69V, 20 hour rate capacity: 92%, -18 DEG C are risen
Dynamic: 1.575V, charge acceptance: 9A, charge hold capacity: 1.49V, electro-hydraulic hold capacity are fine.Indices reach
Or be more than national lead-acid accumulator standard, it is comparatively ideal low internal resistance, high capacity, long-life colloid storage battery.
