<p>This study introduces a facile mechanochemical synthesis of KxMn[Fe(CN)6] (KMnHCF) and carbon nanotube (CNT) composite (KMnHCF@CNT) as a positive electrode material for potassium-ion batteries. The KMnHCF@CNT, synthesized by a simultaneous process of mechanochemical synthesis and carbon compositing, shows a homogeneous composite and achieves a much higher electron conductivity of 7.16 × 10−1 S cm−1 than the KMnHCF and CNT mixture (2.35 × 10−2 S cm−1) synthesized by the two-step process. The improved electron conductivity demonstrates reduced carbon content in the electrode and excellent rate performance of maintaining 80 mAh g−1 at 20 C in potassium cells.</p>
