Scalable Synthesis Nano-Perovskite K(Mn_0.95Ni_0.05)F₃ Cathode by Homogeneous Precipitation Method for Potassium-Ion Batteries.

ABSTRACT: Potassium-ion batteries (KIBs) are favored by researchers because of the unique advantages. In this work, KIB cathode material nano-perovskite K(Mn_0.95Ni_0.05)F₃ with concentration gradient was synthesized by EDTA-assisted homogeneous precipitation method for the first time and characterized. The solid solution material was deposited on the multi-walled carbon nanotubes (MWCNTs) to form K(Mn_0.95Ni_0.05)F₃/MWCNT nanocomposites to improve the electron conductivity of the electrode material so as to obtain the excellent electrochemical performance. As expected, the charge and discharge capacities of K(Mn_0.95Ni_0.05)F₃/MWCNTs after the 60th cycle can still reach 106.8 and 98.5 mAh g^-1 ove
