Dry Upcycling of Spent Zn‐C Primary Battery Black Mass Into <scp> ZnMn <sub>2</sub> O <sub>4</sub> </scp> Electrodes for Supercapacitors

Spent Zn‐C primary batteries represent an abundant secondary resource of Zn‐ and Mn‐containing black mass, yet most recycling approaches rely on multistep hydrometallurgical or high‐temperature pyrometallurgical processing. This study presents a sustainable and entirely dry upcycling route that converts spent black...
