英文摘要	Potassium-ion batteries (KIBs) are favored by researchers because of the unique advantages. In this work, KIB cathode material nano-perovskite K(Mn0.95Ni0.05)F-3 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(Mn0.95Ni0.05)F-3/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(Mn0.95Ni0.05)F-3/MWCNTs after the 60th cycle can still reach 106.8 and 98.5 mAh g(-1) over the voltage range 4.2-1.2V vs. K/K+ at the current density of 35mAg(-1), respectively. Electrochemical performance studies showed that solid solution K(Mn0.95Ni0.05)F-3 had the potential applications as the cathode material for KIBs. Electrochemical impedance spectroscopy (EIS) was used to study the transport and reaction processes of ions at the solid-liquid interface. The main factors affecting electrochemical performance could be analyzed from the Nyquist plot of the EIS test.
