Various fields in the national economy such as national defence, it has also become indispensable energy products in social production and human lives.
Lead-acid accumulator is widely applied to every field, especially field of telecommunications, stand-by power supply, accumulation power supply always
With power applications etc., but traditional lead-acid accumulator there is also premature capacity loss, and service life is short to wait series of problems, its disease
Shape 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 pb of formation2+Ion immediately with
so4 2-Ionic reaction, is deposited into insoluble lead sulfate at the electrode surface.At negative electrode (positive plate), from the electronics of external circuit
By pbo2It is reduced to water and pb2+Ion, pb2+Ion is reacted with sulfate ion, by pbso again immediately4It is deposited on electrode.Electric power storage
When electric discharge completely in pond, negative electrode (positive plate) and anode (negative plate) are transformed substantially into pbso4(Gu).The additional reverse electricity of accumulator
, there is reversible electrochemical reaction in pressure, that is, accumulator charges.During overcharge, positive plate generates thick titanium dioxide lead layer and release oxygen
Gas, negative plate forms biscuit lead layer and release hydrogen.
Five big ingredients of lead-acid accumulator are positive pole, negative pole, barrier film, electrolyte and battery case, wherein electrolyte
It is one of principal element of impact battery performance.Common electrolyte internal resistance is big, Gu sour ability, service life are short.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of lead-acid accumulator electrolyte and accumulator, can significantly improve
Its access times and service life.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows.

For solving the above problems, the embodiment of the present invention additionally provides a kind of lead-acid accumulator, comprises above-mentioned lead acid storage battery
Pond electrolyte.
The method have the advantages that
By 4,5- carbovinate vinylene, 4- methyl -5- propyl group vinylene carbonate, propylene sulfite and first
The interpolation of base tertbutyl ether, so that electrolyte has suitable dielectric constant and viscosity, defines form compact and stable sei film, with
When improve high temperature sei film stability at high temperature, 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, mixed by a certain percentage as sulphuric acid electricity using s-triazine and sulphuric acid
Solution solution additive；The mechanism of action is mixed up by the coordination of s-triazine, reduces polar plate of lead acid storage battery sulfation, improve battery electricity
Chemical property improves circulating battery service life, and ammonium sulfate, magnesium sulfate and sodium ethylene diamine tetracetate collectively form deoxidizer, in lead
During the use of acid accumulator, pole plate due to overcharging, cross put, the reason such as dehydration that the impact such as temperature causes or sulfuration, meeting
Form acidification phenomenon, lead to lead oxide to come off, pole plate is loose, poor activity, the deoxidation of this deoxidizer is to assist lead sulfate
Granule quickly decomposes and reduction.The moisture in electrolyte can be supplemented, solve the problems, such as dehydration, the adjustment of ph value exist simultaneously
Optimum state, polyvinyl alcohol can increase active material utilization with metal ion-chelant.Polyglycol ether can improve nanoscale
Silicon dioxide dispersibility in the electrolytic solution, makes electrolyte more stable, and what alleviation battery was subject to well shakes.
