Electrolyte of super battery

Abstract

The invention discloses an electrolyte of a super battery. The electrolyte comprises 35-50% of sulfuric acid, 1-10% of a silicate, 0.1-2% of sodium hexametaphosphate, 0.2-1% of nanometer carbon, 0.3-1.5% of cetyltrimethylammonium bromide, 0.1-1.5% of a sulfate, 0.02-0.4% of a polymeric stabilizing agent and 45-52% of water. The electrolyte of the invention allows the charging accept capability of the battery to be improved and the cycle life of the battery to be obviously improved. The electrolyte has the advantages of no generation of corrosive gases in the production process, realization of no pollution in the preparation process and the use process and no pollution of wastes, and fundamental solving of main disadvantages of electrolytes of traditional lead acid batteries.

Description

[0001] technical field [0002] The invention relates to the field of storage batteries, in particular to an electrolyte for a super battery. Background technique [0003] Lead-acid battery is the most mature battery among all chemical power sources. It has low price, high safety, and is the most widely used secondary battery at present. Shortcomings such as short battery life and difficulty in fast charging greatly limit its application, and with the development of electronic instruments and electric vehicles, higher requirements are placed on matching batteries and their performance. A lot of research has been done on the specific energy and active material utilization, and it is found that adding appropriate additives can effectively improve battery performance, including positive electrode additives, negative electrode additives and electrolyte additives.

AI Technical Summary

Problems solved by technology

[0004] Traditional lead-acid batteries use sulfuric acid solution as the electrolyte, which causes destructive pollution to the natural environment during production, use and disposal, which has become a fatal injury to the development of this product

Moreover, a large amount of acid mist will be generated during the charging and discharging process, which will cause serious pollution. Corrosive gases will be generated during the production process, polluting the environment, and the acid stratification effect of the electrolyte. The sulfuric acid generated during charging tends to sink to the bottom of the battery. In the presence of a vertical concentration gradient, the reduction of PbS04 at the bottom becomes more difficult and the bottom is sulphated first

If the battery loses water, the acid concentration of the electrolyte increases, which also increases the possibility of sulfation of the negative electrode and eventually leads to battery failure.
