Abstract

This study presents a comprehensive valorization strategy for spent zinc-carbon batteries, converting both black mass and graphite rod into high-performance carbon dots-decorated zinc oxide (ZnO-CDs) material for energy storage and photocatalytic applications. Selective alkaline leaching achieved an 82% zinc recovery with minimal co-dissolution of manganese (
