Abstract
The invention, belonging to an electrolyte, particularly discloses a novel electrolyte as a medium for a chemical battery or an electrolytic capacitor. The electrolyte comprises 53-57 weight portions of pure water, 42-46 weight portions of sulfuric acid, and 0.8-1.2 weight portions of anhydrous sodium sulfate. According to the invention, the problems that easy volatilization and seepage and large influence to service life and stability in a high temperature environment, and possible instant vaporization under high temperature high pressure, explosion caused by volume increasing, and low conductivity of the ionic conduction method used by the electrolyte existing in the electrolyte in the prior art are solved.
Description
Technical field
The present invention relates to electrolyte, be specifically related to the electrolyte that a kind of chemical cell or electrochemical capacitor are used as medium.
Background technology
Electrolyte is the most traditional electrolyte, and electrolyte adds salt of weak acid electric capacity matter by organic solvent and obtains through heating.The negative electrode of the alminium electrolytic condenser on the common meaning all is this electrolyte.Electrolyte is the medium (certain corrosivity is arranged) of uses such as chemical cell, electrochemical capacitor, and for their operate as normal provides ion, and the chemical reaction that takes place in the assurance work is reversible.Use electrolyte to do negative electrode many benefits are arranged.The contact area that at first is liquid and medium is bigger, and is helpful to promoting capacitance like this.The electrochemical capacitor that next is to use electrolyte to make, the high temperature of the highest ability 260 degree so just can be through wave-soldering (wave-soldering be one important procedure that the SMT paster is installed), resistance to pressure is also more intense simultaneously.In addition, use electrolyte to do the electrochemical capacitor of negative electrode, after medium was breakdown, as long as breakdown current does not continue, electric capacity can self-healing so.But existing electrolyte also has its weak point.At first be volatilization, seepage easily under hot environment, very big to life-span and stability influence, electrolyte also might instant vaporization under HTHP, and volume increases and set off an explosion (be exactly us the normal quick-fried slurry of saying); Next is that its conductance of ion guide electrical method of adopting of electrolyte is very low, has only 0.01S (conductivity, the inverse of ohm)/CM, and this causes the ESR value (equivalent series resistance) of electric capacity high especially.
The electrolyte of storage battery by special-purpose sulfuric acid and the formulated by a certain percentage density of distilled water generally be 1.24-1.30g/cm cube.Proportion 12.75-1.285G/CM3 sulfuric acid adds pure water, if water consumption in the battery use adds the pure water charging and gets final product.
Summary of the invention
The purpose of this invention is to provide novel electrolyte; The invention solves the volatilization easily under hot environment of existing electrolyte, seepage, very big to life-span and stability influence; And the also possible instant vaporization of electrolyte under HTHP; The volume increase sets off an explosion the very low problem of its conductance of ion guide electrical method that electrolyte adopted.
Novel electrolyte of the present invention is made up of following raw materials by weight percent: pure water 53-57, sulfuric acid 42-46, anhydrous sodium sulfate 0.8-1.2.
Further, novel electrolyte of the present invention also has following characteristics, is made up of following raw materials by weight percent: pure water 54-56, sulfuric acid 43-45, anhydrous sodium sulfate 0.9-1.1.
Further, novel electrolyte of the present invention also has following characteristics, pure water 53-56, sulfuric acid 43-45, anhydrous sodium sulfate 0.8-1.1.
Further, novel electrolyte of the present invention also has following characteristics, is made up of following raw materials by weight percent: pure water 53-56, sulfuric acid 43-46, anhydrous sodium sulfate 0.9-1.2.
The concentration of above-mentioned sulfuric acid is 98%.
Electrolyte of the present invention has the volatilization of under hot environment, being not easy, seepage, long service life, and stable performance, electrolyte can instant vaporization under HTHP, and is safe in utilization, the advantage that conductivity is good.Electrolyte of the present invention is particularly suitable in storage battery, acting on.
