Utility
Systems and methods for continuous alkaline lead acid battery recycling
27 Jul 21
Lead is recycled from lead paste of lead acid batteries in a process that employs alkaline desulfurization followed by formation of plumbite that is then electrolytically converted to pure lead.

Utility
Electrodeposited lead composition, methods of production, and uses
22 Jun 20
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.
