Electrolyte for accumulator without maintenance

Abstract

The invention relates to an accumulator non-maintenance electrolyte which belongs to field of lead-acid accumulator. The accumulator non-maintenance electrolyte comprises by volume percent: 0.1-0.3 of magnesium carbonate, 3-5 of rosin powder, 0.2-0.3 of humic acid, 0.3-0.4 of potassium permanganate, 2-3 of protanetrione, and the balance of dilute sulfuric acid with specific gravity of 1.27. Advantages of the accumulator non-maintenance electrolyte are that: generation of sulfated pole plate and abscission of pole plate active material are avoided, transition of complex particles are generated, evacuation is magnified, liquid surface tension and adhesive force is increased, reaction speed of ions is quickened, terminal voltage and starting current of accumulator are increased, the electrolyte is not easy to ice in winter and volatilize in summer, quality and purity of electrolyte are greatly increased.

Description

1. Technical field [0001] The invention relates to a storage battery maintenance-free electrolyte, which belongs to the field of lead-acid storage batteries. 2. Background technology [0002] In the past, the electrolyte was only prepared as a dilute sulfuric acid solution with a specific gravity of 1.28. This electrolyte is easy to evaporate the water in the electrolyte during charging, discharging and use, which will increase the specific gravity of the dilute sulfuric acid solution. If the water is not replenished in time, the plate will be severely corroded, causing the active material of the positive plate to fall off, vulcanize and short circuit. . In addition, the starting performance of the vehicle is poor, and the volatilization loss is too large in summer, resulting in a lack of liquid, which makes the pole plate exposed to the air, and the pole plate is oxidized and thickened to pierce the separator and cause a short circuit between the poles. This is one of the...

This electrolyte is easy to evaporate the water in the electrolyte during charging, discharging and use, which will increase the specific gravity of the dilute sulfuric acid solution. If the water is not replenished in time, the plate will be severely corroded, causing the active material of the positive plate to fall off, vulcanize and short circuit.

In addition, the starting performance of the vehicle is poor, and the volatilization loss is too large in summer, resulting in a lack of liquid, which makes the plates exposed to the air, and the plates are oxidized and thickened to pierce the separator and cause a short circuit between electrodes.
