Description
Technical field
The invention belongs to accumulator field, be specifically related to a kind of electrolyte of nano-colloid storage battery.
Background technology
Storage battery is also called accumulator, is the equipment that chemical energy becomes electric energy.Lead-acid accumulator since invention, has been had the history of more than 100 year from 1958 so far.Lead-acid accumulator has simple in construction, dependable performance, easy to use, raw material are easy to get and the advantage such as low price, it is widely used in the various fields in the national economy such as transportation, communication and national defence, it has also become social production and indispensable energy products in 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 traditional lead-acid accumulator there is also premature capacity loss, service life short wait series of problems, its symptom is positive plate grid corrosion, lead plaster softening and shedding, negative pole sulfation etc..Lead-acid accumulator connect circuit discharging time, electronics by anode (negative plate) discharge, the Pb2+ ion of formation immediately with SO42-ionic reaction, deposit into insoluble lead sulfate at the electrode surface.At negative electrode (positive plate), PbO2 is reduced to water and Pb2+ ion by the electronics from external circuit, and Pb2+ ion reacts with sulfate ion again immediately, is deposited on electrode by PbSO4.When accumulator is discharged completely, negative electrode (positive plate) and anode (negative plate) be transformed substantially into PbSO4 (Gu)., there is reversible electrochemical reaction, i.e. accumulator charging in the additional backward voltage of accumulator.During overcharge, positive plate generates thick titanium dioxide lead layer and releasing oxygen, and negative plate forms biscuit lead layer and release hydrogen.
The five of lead-acid accumulator are big, and ingredient is 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 big, and solid sour ability, service life are short.
Accumulator is the energy carrier of electric motor car, and current electromobile battery is mostly lead-acid accumulator, this battery liquid facile hydrolysis, layering, and battery acid amount is few, and battery performance declines fast, and easily fills drum when charging, it is difficult to meet the demand for development of current power car.
Summary of the invention
Goal of the invention: present invention aims to the deficiencies in the prior art, it is provided that a kind of electrolyte of nano-colloid storage battery.
Technical scheme: in order to reach foregoing invention purpose, the present invention is specifically achieved like this: a kind of electrolyte of nano-colloid storage battery, described electrolyte comprises the component of following weight portion: 43.0～44.0 parts of sulphuric acid；Deionized water 54.8～55.8 parts；Nano silicon 0.8～1.5 part；0.008～0.013 part of surfactant；Stabilizer 0.05～0.10 part；α naphthols acid 0.008～0.013 part；O-methoxybenzaldehyde 0.02～0.04 part；Sulfoxide additive 1～3 part；2,4,6-tri-thiol s-triazine trisodium-salt solution 3～8 parts.
