Problems solved by technology

According to research at home and abroad, such as "Research Progress on Carbon Additives for Valve Regulated Lead-acid Batteries for Hybrid Electric Vehicles" written by Zhao Jiequan and Liu Houtian, it is pointed out that directly adding a large amount of carbon to the negative electrode paste will easily cause carbon dioxide in the cycle process. The shedding of the lead paste reduces the life of the battery

Abstract

The invention relates to a lead and carbon composite material-containing lead-carbon super storage battery. The anode active material of the lead-carbon super storage battery contains the lead and carbon composite with high specific capacitance. The anode material of the lead-carbon super storage battery comprises 1 to 75 weight percent of lead, 2 to 95 weight percent of lead and carbon compositematerial with high specific capacitance and 1.5 to 5 weight percent of additive. The lead-carbon super storage battery provided by the invention can be manufactured by fewer steps, has a simple internal structure, is low in cost and has a long service cycle life due to the fact that the anode lead plaster is insusceptible to stripping.

Description

technical field [0001] The invention belongs to the technical field of lead storage batteries, and in particular relates to a lead-carbon super storage battery containing a lead-carbon composite material negative electrode and a preparation method thereof. Background technique [0002] Lead-acid batteries have a history of more than 150 years. Because of their good reliability, high cost performance, rich resources and recyclability, they have been widely used in social life, industrial production and even military fields. [0003] With the rapid development of the global economy and society, petrochemical resources and energy are becoming increasingly scarce, the ecological environment is deteriorating, and the pressure on environmental protection is increasing sharply. Human beings will be more dependent on renewable energy such as solar energy, wind energy, biomass energy, and hydrogen energy. Therefore, electric vehicles and The development of solar energy, wind energy a...
