Problems solved by technology

[0002] The so-called storage battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary. After discharge, it can regenerate internal active substances by charging—store electrical energy as chemical energy; convert chemical energy again when it needs to be discharged For electrical energy, this type of battery is called a battery, also known as a secondary battery. The battery is a chemical "power source" widely used in the world. It has the characteristics of stable voltage, safety and reliability, low price, wide application range, rich raw materials and recycling. The advantage of high utilization rate is that it is the battery with the largest output and the widest application among all kinds of batteries in the world. The plates of ordinary batteries are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are: The voltage is stable and the price is cheap; the disadvantages are low specific energy, short service life and frequent daily maintenance. However, due to the large amount of sulfuric acid used in the production process of ordinary batteries, it causes serious pollution to the environmental soil and water sources. At the same time, because ordinary batteries mostly use lead , Mercury, and cadmium alloys are used as plates. In order to prevent the vulcanization of battery plates, frequent daily maintenance will lead to acid corrosion and acid mist pollution, and mercury and cadmium poisonous pollution after vulcanization of plates can cause irreversible damage to personnel and the environment. At the same time, because the discarded electrolyte of ordinary batteries is not easy to recycle, the lead sulfate in it will cause great pollution and damage to the soil and water environment

Abstract

The invention discloses silicon-magnesium compound salt electrolyte for a storage battery. The silicon-magnesium compound salt electrolyte is characterized by being prepared by mixing the following components according to weight percent: 15-24% of silicate, 13-20% of magnesium salt, 3-6% of corrosion inhibitor, 5-10% of antioxidant, 7-10% of catalyst, 0.5-3% of stabilizer, 10-15% of dispersant and11-41.5% of solvent. All the components coordinate and react with each other, so that the prepared electrolyte is environmentally friendly and non-toxic; sulfuric acid is not used in the mixing and preparing process, so that the environment, soil and water source are not contaminated seriously, further, frequent routine maintenance caused by vulcanization of a polar plate of the storage battery is prevented, so that acid corrosion and acid mist pollution are not caused, in addition, waste electrolyte is easy to recycle and has a long service life.
