Problems solved by technology

Although they have a certain ability to remove lead sulfate deposits on corroded lead plates, they cannot prevent the formation of irreversible lead sulfate
The liquid additive can only maintain the original performance of the battery during the whole use of the battery, but has no obvious effect on prolonging the life of the battery
In addition, when these liquid additives are added to the battery, the operation is very troublesome

Embodiment

[0016] Get eight 12V, 60Ah accumulators, and add 10 grams of 2,6-di-tert-butyl p-cresol and 2-mercaptobenzimidazole allyl sulfide mixture respectively to six of them as anti-aging agent (wherein antioxidant and anti-aging The agent weight ratio is 99:1), after three fillings and two discharges, the two sections are used as a group to do the following experiments. Store the two sections in a ventilated place, and test their performance according to the national standard after three months; test the performance of the two sections at -40°C according to the national standard; store the two sections and the other two sections without additives at -18°C Next, carry out the test of all items according to the national standard, until the storage battery battery life ends, promptly draw the test result (ie advantage) of the present invention.

Abstract

There is a kind of inhibitor for lead-acid secondary cell, its character is that it adds 2, 6-ditertiary butyl p-toluene cresel used as antioxidant and 2-sulfydryl benzene-imidazole propyl sulfur aether used as inhibitor into electrolyte of the secondary cell. It enhances operating factor of active material in the secondary cell through coordination effect of the two compounds, it has functions of antioxidation, resistant to corrosion and sedimer eliminating, it protects the plates of the secondary cell, the lead surface sediment created in oxidation-reduction process of the secondary cell is deoxidized into lead and lead oxide farthest of realize that the secondary cell nearly does not create the lead sulfate sediment. Thus, it keeps the attachment area of the charges effectively and transmits the charges swimmingly.

Description

technical field [0001] The invention belongs to the class of chemical additives, in particular to an antiaging agent for lead-acid storage batteries. Background technique [0002] At present, most lead-acid battery additives are liquid. Although they have a certain ability to remove lead sulfate deposits on corroded lead plates, they cannot prevent the formation of irreversible lead sulfate. During the whole use of the battery, the liquid additive can only maintain the original performance of the battery, but has no obvious effect on prolonging the life of the battery. In addition, these liquid additives are cumbersome to handle when added to the battery. Contents of the invention [0003] The purpose of the present invention is to avoid the disadvantages of the above-mentioned prior art and provide a lead-acid battery anti-aging agent that can significantly improve the service efficiency of the battery and prolong the service life. [0004] The object of the present in...
