Embodiment

[0008] The preparation method of the electrolyte of the present invention is: add 0.5-1.5 parts of ethanol and 1-3 parts of phosphoric acid into 47-50 parts of sulfuric acid with a specific gravity of 1.530-1.600, stir evenly at normal temperature, take the sulfuric acid solution and the silica sol solution respectively One portion, mix and stir well to infuse into the accumulator.

[0009] Compared with the prior art, the present invention, due to the addition of ethanol, one prolongs the coagulation time of the colloid by about 7 minutes, which increases the operating time of the hair process, and the other is that the colloid shrinkage rate decreases, the sulfuric acid content increases, and the battery capacity increases. The resistance is significantly reduced and the life span is increased. After testing the sample, the initial starting capacity: 1.69V, 20-hour rate capacity: 92%, -18°C starting: 1.575V, charging acceptance capacity: 9A, charging storage capacity: 1.49V,...

Abstract

The invention relates to a method for improving performance of transforming chemical energy of a storage battery into electric energy. The electrolyte contains: 1%-3% of phosphoric acid, 0.5%-1.5% ofethanol, 47%-49% of silica sol, and the balance of sulfuric acid having a specific gravity of 1.530 to 1.600. Compared with the prior art, since the scheme of the invention adopts the ethanol silica gel electrolyte, the internal resistance of colloidal electrolyte is obviously reduced, the battery capacity is increased, and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to a method for improving the chemical energy conversion of a storage battery into electric energy. Background technique [0002] Gel batteries have been widely used in society due to their characteristics of no acid leakage and long battery life, and their electrical performance has gradually improved with the deepening of research. Application number is 88106105.0 in the Chinese invention patent application open specification has introduced a kind of manufacturing method of low-maintenance energy-storage silica gel storage battery, and it is that the content of 5 / 1000-30 / 1000 is 85% phosphoric acid and 5 / 1000-15 / 1000 of oxalic acid. The addition of phosphoric acid and oxalic acid has undoubtedly played a certain role in improving the electrical performance of the battery, but the internal resistance and capacitance of the battery are still not very satisfactory. Contents of the invention [0003] The purpose of the present ...
