Description
Technical field
The present invention relates to battery technology field, especially a kind of battery liquid and storage battery.
Background technology
Lead acid accumulator by since invention, has had the history of more than 100 year from 1958 so far.Lead acid accumulator has that structure is simple, dependable performance, easy to use, raw material are easy to get and the advantage such as low price, be widely used in the various fields in the national economy such as communications and transportation, communication and national defence, become indispensable energy products in social production and human lives.
Lead acid accumulator is widely applied to every field always, especially field of telecommunications, stand-by power supply, accumulation power supply and power applications etc., but also there is premature capacity loss in traditional lead acid accumulator, useful life short wait series of problems, its symptom is positive plate grid corrosion, lead plaster softening and shedding, negative pole sulfation etc.
When circuit discharging connected by lead acid accumulator, electronics is discharged by anode (negative plate), the Pb2 of formation
+ion immediately with SO42
-ionic reaction, is deposited as insoluble lead sulfate at the electrode surface.At negative electrode (positive plate), PbO2 is reduced to water and Pb2 by the electronics from external circuit
+ion, Pb2
+ion reacts with sulfate ion again immediately, is deposited on electrode by PbS04.When storage battery discharges completely, negative electrode (positive plate) and anode (negative plate) substantially change into PbSO4 (Gu)., there is reversible electrochemical reaction, i.e. charge in batteries in the additional reverse voltage of storage battery.During overcharge, positive plate generates thick titanium dioxide lead layer and releasing oxygen, and negative plate forms biscuit lead layer and release hydrogen.
Five large parts of lead acid accumulator are positive pole, negative pole, barrier film, electrolyte and battery case, and wherein electrolyte is one of principal element affecting battery performance.Common electrolyte internal resistance is large, Gu sour ability, useful life are short.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of battery liquid and storage battery, can significantly improve its access times and useful life.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of battery liquid, comprise the sulfuric acid of 37wt% ~ 45wt%, the stannous sulfate of 0.3wt% ~ 0.7wt%, the ammonium sulfate of 0.14wt% ~ 0.4wt%, the sodium sulphate of 0.42wt% ~ 0.92wt%, 4 of 0.5wt% ~ 0.6wt%, 5-carbovinate vinylene, 4-methyl-5-propyl group the vinylene carbonate of 0.5wt% ~ 3.5wt%, the cyclohexylbenzene of 0.3wt% ~ 0.62wt%, the methyl phenyl ethers anisole of 0.1wt% ~ 0.54wt%, the modified polyacrylamide of 0.3wt% ~ 0.5wt%, the EDETATE SODIUM of 0.3wt% ~ 0.7wt%, 0.05wt% ~ 0.2wt%2, 6-di-tert-butyl-4-methy phenol, 0.05wt% ~ 0.2wt%1(H)-2-p-chlorobenzyl benzimidazole, the sulfoxide additive of 1wt% ~ 3wt%, 2 of 4wt% ~ 8wt%, 4, 6-tri-thiol s-triazine trisodium-salt solution, 5wt%-10wt% nanometer grade silica, surplus is deionized water.
Preferably, described sulfoxide additive is one or more the mixture in dimethyl sulfoxide (DMSO), diphenyl sulfoxide, thionyl chloride, sulfolane or dipropyl sulfone.
Preferably, the purity of described sulfuric acid is for analyzing pure rank.
Preferably, described deionization resistivity of water >=18M Ω.
For solving the problem, the embodiment of the present invention additionally provides a kind of lead acid accumulator, comprises above-mentioned lead-acid accumulator electrolyte.
The present invention has following beneficial effect:
By 4,5-carbovinate vinylene, 4-methyl-5-propyl group vinylene carbonate, the interpolation of propylene sulfite and methyl tertiary butyl ether(MTBE), electrolyte is made to have suitable dielectric constant and viscosity, define form compact and stable SEI film, improve high temperature SEI film stability at high temperature simultaneously, improve the resistance to elevated temperatures of electrolyte, the use of sulfoxide additive, cycle performance and the high temperature performance of electrolyte can be improved, adopt s-triazine to mix as sulphuric acid electrolyte solution additive by a certain percentage with sulfuric acid; The mechanism of action is mixed up by the coordination of s-triazine, reduce polar plate of lead acid storage battery sulfation, improve battery performance and improve circulating battery useful life, ammonium sulfate, magnesium sulfate and sodium ethylene diamine tetracetate form deoxidier jointly, in the use procedure of lead acid accumulator, the reasons such as the dehydration that the impacts such as pole plate is put owing to overcharging, excessively, temperature cause or sulfuration, acidification phenomenon can be formed, cause lead oxide to come off, pole plate is loose, poor activity, the deoxidation of this deoxidier assists lead sulfate particle to decompose fast and reduction.Can supplement the moisture in electrolyte, solve mistake water problem, adjust pH value in optimum state, nanometer grade silica has good thixotropy, mobility and thickening property simultaneously.
