Low-defect K2Mn[Fe(CN)6]-reduced graphene oxide composite for high-performance potassium-ion batteries†
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.
