Lead content of lead-acid battery lead paste

What are the components of a spent lead-acid battery?

Lead sulfate, lead dioxide and lead oxide are the main components of lead paste in a spent lead-acid battery. In addition, there are a few impurities in spent lead paste, which have great influence on the performance of the new battery; therefore, it is necessary to remove them. In this study, a novel approach with

Can lead paste be recycled from spent lead acid battery under vacuum?

Conclusions A research investigation for recycling lead from lead paste in the spent lead acid battery under vacuum has been developed in this work.

What is the recovery of lead from spent lead acid battery paste (SLP)?

The recovery of lead from spent lead acid battery paste (SLP) is not only related to the sustainable development of the lead industry, but also to the sustainable evolution environment.

How are lead-acid batteries separated?

Usually, spent lead-acid batteries are separated in lead recycling plants by dismantling and sorting into four fractions: lead paste, metallic fragments, waste acid, and plastic case ( Worrell and Reuter, 2014; Zhang et al., 2019 ). The processing of lead paste is relatively complex because it contains refractory lead sulphate.

Can spent lead paste be converted into high purity metal lead?

The experimental results demonstrate that spent lead paste could be well converted into high purity metal lead via the cooperative electrochemical reduction and desulfurization approaches during the direct electrolysis process.

Is spent lead acid battery a contaminant?

With the wide application of lead acid battery, spent lead acid battery has become a serious problem to environmental protection and human health. Though spent lead acid battery can be a contaminant if not handled properly, it is also an important resource.
