Abstract
The present disclosure relates generally to recycling lead-acid batteries, and more specifically, relates to purifying and recycling the lead content from lead-acid batteries. A method includes reacting a lead-bearing material with a first carboxylate source to generate a first lead carboxylate. The method includes reacting the first lead carboxylate with a second carboxylate source to generate a second lead carboxylate. The method further includes applying an electrical bias to an aqueous solution of the second lead carboxylate to generate metallic lead.
