1. A method of forming a new lead-acid battery from recycling of a lead-acid battery comprising:
processing a spent lead-acid battery to generate a lead-bearing material;
forming a mixture comprising a carboxylate source and the lead-bearing material;
generating a lead salt precipitate in the mixture as the carboxylate source reacts with the lead-bearing material;
dissolving the lead salt precipitate;
isolating a liquid component of the mixture from one or more insoluble components of the mixture;
regenerating the lead salt precipitate;
isolating the regenerated lead salt precipitate from the liquid component of the mixture;
adding a hydride source to the liquid component;
treating the lead salt precipitate to yield a leady oxide;
forming a leady oxide active material with the leady oxide; and
forming a new lead-acid battery using the leady oxide active material.
