posted on 2024-01-24, 00:46 authored by Tomooki HOSAKA, Nobuhito NORO, Shinichi KOMABA<p>This study introduces a facile mechanochemical synthesis of K<i><sub>x</sub></i>Mn[Fe(CN)<sub>6</sub>] (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<sup>−1</sup> S cm<sup>−1</sup> than the KMnHCF and CNT mixture (2.35 × 10<sup>−2</sup> S cm<sup>−1</sup>) 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<sup>−1</sup> at 20 C in potassium cells.</p>
