"Reforming Magnet Waste to Prussian Blue for Sustainable Sodium-Ion Bat" by Qing Yan Li, Chunmei Xu et al.
Increasing generation of permanent magnet waste has resulted in an urgent need to preserve finite resources. Reforming these wastes as feedstock to produce renewables is an ideal strategy for addressing waste and energy challenges. Herein, our work reports a smart and sustainable strategy to convert iron in magnet wastes into Prussian blue analogues that can serve as cathode materials for sodium-ion batteries. Moreover, a method to control feed rates is proposed to generate high-quality materials with fewer [Fe(CN)6] vacancies at a feed rate of 3 mL min-1. The recycled Na1.46Fe[Fe(CN)6]0.85·â...
