ABSTRACT A large number of spent sodium‐ion batteries (SIBs) will be produced as SIBs become more widely used. However, components SIBs, such the cathode Prussian white Na 2 Mn[Fe(CN) 6 ], are toxic and hazardous, leading to water soil pollution posing a threat human health. Therefore, recycling is important meaningful. Here, we use phytic acid‐based low‐melting mixture solvents (LoMMSs) for efficient recovery hazardous at mild temperatures. Results show that highest leaching efficiency from could reach 94.7% by polyethylene glycol 200:phytic acid (14:1) 80°C 24 h with liquid/solid ratio 50:1. Furthermore, metal extracted leachate found precipitate when used anti‐solvent, ammonium hydroxide achieving precipitation 89.3% room temperature.
