Morphology control and interface characteristics of well-dispersed nanomaterials in K-ion batteries

Potassium ion batteries (KIBs), the working mechanism of which is similar to that of lithium-ion batteries (LIBs), have drawn much interest as power sources for large-scale grid energy storage because of their low cost and abundant resources. In this paper, the feasibility of KMnF(3) as a cathode ma...

Sumario:Potassium ion batteries (KIBs), the working mechanism of which is similar to that of lithium-ion batteries (LIBs), have drawn much interest as power sources for large-scale grid energy storage because of their low cost and abundant resources. In this paper, the feasibility of KMnF(3) as a cathode material for KIBs, the optimization of synthesis conditions and the interface characteristics of the charge and discharge process have been studied in detail. The study of interface characteristics is mainly done through the non-destructive test of electrochemical impedance spectroscopy (EIS).
