Abstract

The invention provides electrolyte solution for preparing sodium silicate storage battery. The electrolyte solution comprises, by volume, 12%-15% of sodium silicate (Na2OSiO2) comprising 31%-37.9% of silica (SiO2) granules, 11%-16% of sodium sulfate, 9%-10% of sodium carbonate, 0,014%-0.028% of poly-3-chlorobutylene, 0.38%-1.18% of amino-polysiloxane, and the balance water. The invention further provides a method for preparing the electrolyte solution. The method includes the following steps of preparing raw materials according to the above ratio, heating the raw materials in a high-pressure container with internal pressure ranging from 2.85 to 6.17 megapascals to 100-400 DEG C, keeping the temperature and pressure conditions for 21-31 hours, and cooling to obtain clear sodium silicate liquid electrolyte solution with nano-scale silicon dioxide (SiO2) granulated. Severe acid mist pollution generated by preparation of electrolyte solution of a conventional lead-acid battery is avoided, so people and environment can be protected from pollution. Difficulties of hydrogen evolution flash explosion and acid mist corrosion are solved, scrapped electrolyte is pollution-free and easy to deal with and can be utilized as acid compound fertilizer, and the battery counter electrode can also be recycled.

Description

technical field [0001] The invention relates to a sodium silicate accumulator, in particular to an electrolytic stock solution for manufacturing a sodium silicate accumulator and a method for preparing the electrolytic solution. Background technique [0002] In 1859, French engineer Plante invented the lead-acid battery, which brought profound changes to the development of human productivity and social progress. However, the pollution caused by lead-acid batteries in the process of manufacture and use and their wastes also brings serious harm to human beings. It is especially worth noting that a large proportion of lead-acid batteries in my country are still old-fashioned open batteries, which are prone to gas and acid during use. A certain amount of lead and sulfuric acid are released into nature every year. According to statistics, a rotten small lead-acid battery can make one square meter of land useless. Traditional lead-acid batteries have become a serious source of ...
