Scalable Mechanochemical Synthesis of High-quality Prussian Blue Analogues for High-Energy and Durable Potassium-Ion Batteries

Prussian blue analogues (PBAs) are recognized as promising cathode materials for potassium-ion batteries (PIBs), particularly the low-cost and high-energy K 2 Mn[Fe(CN) 6 ](KMnF). However, conventional solution-based synthesis inevitably introduces [Fe(CN) 6 ] 4- defects and lattice...
