摘要： The inventive subject matter is directed to continuous electrochemical production of highly pure micro- or nanostructured lead that at least partially encloses the electroprocessing solvent and molecular hydrogen and optional guest compounds to form a mixed matrix. Such compositions are particularly suitable for cold forming of various structures and/or for alloy and composite material production.

摘要： Lead from lead acid battery scrap is recovered in two separate production streams as clean grid lead and as high-purity lead without smelting. In preferred aspects, lead recovery is performed in a continuous process that uses an aqueous electroprocessing solvent and electro-refining and spent electroprocessing solvent can be recycled to the recovery process.
