example 1

[0012] In a negative plate of a lead storage battery, 0.25% by mass ratio of graphene additive is added, and the average number of graphene walls is 3 layers. The pulse cycle life of the lead storage battery prepared by using the additive plate is 40,000 times, and the charging time is shortened by 27%.

example 2

[0014] In a lead storage battery negative plate, 0.12% by mass ratio of multi-walled carbon nanotubes is added, and the average length of the carbon nanotubes is 5 micrometers. The pulse cycle life of the lead storage battery prepared by using the additive plate is 48,000 times, and the charging time is shortened by 35%.

Abstract

The invention relates to a negative plate additive for a lead storage battery. The additive is activated carbon, carbon black, graphene, carbon nano tube, carbon fiber, carbon aerogel, template carbon, mesoporous carbon, carbide derived carbon, polyaniline, polypyrrole, polythiophene, poly-alkylthiophene, poly-p-fluorophenyl thiophene or hydrogen evolution inhibition additive; after the negative plate additive is used, the lead storage battery has excellent pulse cycle life, and the charge acceptance of the lead storage battery is improved; the negative plate additive is used for lead storage batteries in the fields of electric vehicles, energy storage, electric tools, pulse emission, etc.

Description

technical field [0001] The invention relates to an additive for a negative plate of a lead storage battery, which belongs to the field of chemical engineering. Background technique [0002] Energy is the basis for the survival and development of human society, and the utilization of natural mineral energy to electric energy represents the process of technological development. The rapid development of human society in modern times, especially in the last century, has led to a sharp increase in the consumption of human resources, resulting in increasingly tense traditional fossil energy dominated by oil, and causing air pollution to become more serious. It is necessary to seek sustainable development and protect natural resources. and the natural environment has become a serious challenge in the 21st century. Electric energy has become an indispensable clean energy for human society. Any other resource utilization generally requires the use of electric energy. The storage, co...
