Embodiment

[0008] The preparation method of the electrolyte of the present invention is: add 0.5-1.5 parts of sodium hypochlorite and 1-3 parts of phospholipids to 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 sodium hypochlorite, 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 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 c...

Abstract

The invention relates to a method for manufacturing a large-capacity less-maintenance energy storage colloid storage battery. Electrolyte of the storage battery contains 1% to 3% of phospholipid, 0.5%to 1.5% of sodium hypochlorite, 47% to 49% of silica sol and the balance sulfuric acid with the specific gravity being 1.530 to 1.600. Compared with the prior art, the sodium hypochlorite silica electrolyte is adopted in the method, the internal resistance of the colloid electrolyte is significantly reduced, the battery capacity is increased, and the service life is prolonged.

Description

technical field [0001] The invention belongs to a method and a device for directly converting chemical energy into electric energy, in particular it is a manufacturing method of a colloidal storage battery with large capacity and low maintenance. 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 colloidal storage battery of low-maintenance energy storage, and it is that the phospholipid of 5 / 1000-30 / 1000 content is 85% and 5 / 1000-15 / 1000 of oxalic acid. The addition of phospholipids 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...
