Embodiment Construction

[0007] Get three 12V, 60A / H lead-acid accumulators, two of them add 10 grams respectively by compound 2,6-di-tert-butyl-4-methylphenol and 1(H)-2-p-chlorobenzylbenzimidazole The resulting mixture acts as an additive in a weight ratio of the two components of 90:10. After three charges and two discharges, one battery should be stored in a ventilated place, and the first battery and the third battery without this additive should be charged and discharged three times a day in the morning and afternoon, and the output voltage should be measured once a day. After one month, put the two batteries under the condition of -40°C, carry out normal charging and discharging at the same time, measure the output voltage once a day, and after another month, put them in the normal environment and carry out the normal test (same as above). Three months later, the three storage batteries were tested and dissected, and the test results were obtained, showing the advantages of the present inventio...

Abstract

The additive for electrolyte of lead acid accumulator consists of 2, 6-ditert-butyl-4-methyl phenol and 1(H)-2-p-chlorobenzyl benzimidazole in the weight ratio of 9:1. The accumulator with the additive has 1-2 times increased service life, excellent long time charge performance, very low evaporated electrolyte amount, 5 % raised output voltage and excellent low temperature use effect up to -40 deg.c. The additive is white powder, non-toxic, smell-less, no corrosive, and suitable for all kinds of lead acid accumulators, and has no environmental pollution. The additive is convenient in use and once addition is enough to each accumulator.

Description

1. Technical field [0001] The invention relates to a chemical additive, in particular to a lead-acid accumulator electrolyte additive capable of significantly improving the service efficiency and prolonging the service life of the accumulator. 2. Background technology [0002] Most of the existing lead-acid series storage battery additives are liquid, and the main function of the additive is to prevent the lead plate of the storage battery from generating deposits and remove the lead sulfate deposits on the lead plate that has been corroded. After using liquid additives, although the original performance of the battery can be maintained, it has no effect on prolonging the life of the battery. In addition, liquid additives are difficult to operate during use. 3. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a solid additive, which can not only improve the service efficie...
