AI Technical Summary

Problems solved by technology

However, there are many deficiencies in the current battery
(1) Easy to vulcanize: the battery plate is easy to vulcanize, causing damage to the plate and causing the battery to be scrapped prematurely; 75% of the damaged and scrapped batteries are caused by vulcanization
(2) Only 75%-80% of the active substances in the new battery play a role, and some of them do not play a role, and the battery can no longer be used when it is scrapped
(3) Short life: the existing batteries can generally only be used for 8 months, and some can only be used for 3 months
(4) Long charging time: a general battery takes about 70 hours for a single charge
(5) Poor cold resistance: at -20°C, the battery is not easy to start
(6) Poor heat resistance: the electrolyte in the battery is easy to evaporate, and water needs to be added frequently
Although its performance on lead-acid batteries has improved, there is still room for further improvement

Embodiment 1

[0042]Add 125 kg of distilled water to a 300 cubic meter enamel reaction kettle with stirring, slowly add 50 kg of sulfuric acid under continuous stirring, the temperature rises, and when the temperature drops to 25-30°C, add cobalt sulfate 1.4 in order kg, 1 kg of hydroxylamine sulfate, 5 kg of aluminum sulfate, 4 kg of cadmium sulfate, 2.7 kg of magnesium sulfate, and 3 kg of oxalic acid. In the process of adding raw materials, it is necessary to wait for the former raw material to dissolve before adding the latter.

Embodiment 2

[0044] The equipment and steps of this embodiment are the same as those in Embodiment 1. The raw materials are 135 kg of distilled water, 54 kg of sulfuric acid, 1.8 kg of cobalt sulfate, 1.3 kg of hydroxylamine sulfate, 9 kg of aluminum sulfate, 6 kg of cadmium sulfate, 3.7 kg of magnesium sulfate, oxalic acid 5 kg.

Embodiment 3

[0046] The equipment and steps of this embodiment are the same as those in Embodiment 1. The raw materials are 130 kg of distilled water, 52 kg of sulfuric acid, 1.6 kg of cobalt sulfate, 1.2 kg of hydroxylamine sulfate, 7 kg of aluminum sulfate, 5 kg of cadmium sulfate, 3.1 kg of magnesium sulfate, oxalic acid 4 kg.

Abstract

The disclosed activator for lead-acid accumulator includes distilled water, sulfuric acid, cobalt sulfate, hydroxylamine sulfate, aluminum sulfate, cadmium sulfate, magnesium sulfate, and binary carboxylic acid. Advantages are: preventing pole plates from vulcanizing, increasing capacity and service life of accumulator, shortening time for charging accumulator, reducing evaporation of electrolyte in use, reducing internal resistance, avoiding overcharge. Moreover, the invention solves self-discharge issue of accumulator effectively.

Description

technical field [0001] The invention relates to the technical field of electrochemistry, in particular to a lead-acid storage battery activator. Background technique [0002] my country is a big country in the production and use of batteries. Batteries are widely used in mechanical power, firepower, water power, solar energy, wind power generation and other fields, and can also provide electric energy for automobiles, trains, airplanes, ships, ships, tanks, armored vehicles, battery cars, electric bicycles, etc. It goes deep into various fields of national economic construction, national defense construction and daily life. But there are many weak points in present storage battery. (1) Easy to vulcanize: the battery plate is easy to vulcanize, causing damage to the plate and causing the battery to be scrapped prematurely; 75% of the damaged and scrapped batteries are caused by vulcanization. (2) Only 75%-80% of the active substances in the new storage battery play a role,...
