Lead-acid storage battery activation liquid and preparation method thereof

Abstract

The invention relates to a lead-acid storage battery activation liquid. The activation liquid comprises the following components: potassium carbonate, polyaspartic acid potassium, stannous sulfate, polyvinyl alcohol, potassium dihydrogen phosphate, sodium sulfate, sodium carbonate and deionized water. The preparation method of the lead-acid storage battery activation liquid comprises the followingsteps: adding the potassium carbonate, the polyaspartic acid potassium, the potassium dihydrogen phosphate, the stannous sulfate, the sodium sulfate and the sodium carbonate into 80-110 parts of deionized water, and stirring for more than 20 minutes till that solids are completely dissolved to obtain a mixture A; adding the polyvinyl alcohol into 100-120 parts of deionized water in a heating andstirring state, keeping a temperature at 80-95 DEG C, and continuously stirring till that the liquid temperature is reduced to a room temperature so as to obtain a mixture B; and uniformly mixing themixture A and the mixture B to obtain the activation liquid. The activation liquid of a lead-acid storage battery has advantages of short activation time and high activation efficiency; and the activation liquid and the preparation method are simple and feasible, there is no toxic and side effect in a process, safe and environment-friendly performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of battery repair and reuse, and in particular relates to a lead-acid battery activation solution and a preparation method thereof. Background technique [0002] Lead-acid batteries are widely used in communication, electric power, energy storage, automobile, finance, aerospace, rail transit, and TV signal transmission industries due to their advantages of low price, stable voltage, wide operating temperature range, and high current discharge capacity. With the rapid development of the electric bicycle industry, while lead-acid batteries are being used in large quantities, the problem of battery failure and scrapping has also become the focus of attention of governments, enterprises and users in various places; Pollution Prevention and Control Technology Policy" mentions that "encourage scientific and technological research on the regeneration of waste battery resources, develop economical and efficient wast...

AI Technical Summary

Problems solved by technology

This kind of lead sulfate has poor conductivity, high resistance, low solubility and dissolution rate, and it is difficult to dissolve and recover during charging. Its existence hinders the reaction between the active material and the electrolyte, which reduces the action area and the amount of active material. , eventually lead to insufficient battery capacity failure

[0004] After exploration and research, adding activation solution is one of the effective methods to eliminate the degree of vulcanization and improve the charge-discharge cycle performance; however, the existing activators have defects such as long activation time and low activation efficiency, and the overall effect is not good.
