Abstract: The present disclosure provides methods and systems for recovering metals from lithium-ion batteries, and specifically to methods and systems for recovering cobalt and nickel jointly in metallic form via electrowinning processes. The present disclosure further provides methods and systems for preparing lithium-ion battery materials for use in metal recovery processes.

Abstract: A method for manufacturing a high precision hollow metallic component, by obtaining, through extruding or roll forming, a precursor hollow metallic profile having a constant cross section and at least one precursor chamber; positioning the precursor hollow metallic profile in a split-die cavity, wherein at least two walls of said split die cavity have essentially outside dimensions of corresponding walls of the high-precision hollow metallic component; introducing a mandrel made of at least two parts into the precursor chamber; plastically deforming the precursor hollow metallic profile by expanding the mandrel to obtain finished dimensions of the high-precision hollow metallic component; removing the mandrel from the finished chamber after reversing an expanding action. A variable cross section hollow metallic component, with at least two chambers obtained with the method, is also described.
