Abstract

Here, a low-defect K₂Mn[Fe(CN)₆]-reduced graphene oxide (KMF-RGO) composite is fabricated, which demonstrates excellent cycling stability, fast rate capability, and exceptional air stability as a cathode material for potassium-ion batteries (KIBs). This work provides a practical strategy for the synthesis of high-performance K₂Mn[Fe(CN)₆] cathode materials for KIBs.
