Problems solved by technology

[0004] While improving the positive and negative active materials, it is also necessary to improve the problem of electrolyte stratification. The existing method is to use colloidal electrolyte, but in the process of adding liquid, it is difficult for the glue to be added to the inside of the plate. The battery found that on the plate, the stratification of the acid still exists

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a lead paste for deep glue-type super solid lead-carbon batteries. Background technique [0002] At present, the lead-acid battery market for electric vehicles is increasingly saturated, and competition and price wars are extremely fierce. However, national policies have marginalized lead-acid batteries and vigorously supported the application of lithium batteries in electric vehicles. The survival of lead-acid battery manufacturers is facing difficulties. It is an unprecedented crisis, but if the specific energy of lead-acid batteries can be improved, the charging efficiency can be improved, and the service life can be extended, plus the advantages of lead-acid batteries compared to lithium batteries in terms of rich resources, high cost performance, recyclability, and safety, etc., then Lead-acid batteries still have room to survive. [0003] At present, the develo...
