Besides lithium-ion battery (LIB), potassium-ion battery is also potentially developed as an alternative battery with cheaper and more secure battery. The synthesize of complex compounds of KCu[Fe(SCN)6] was conducted using a direct reaction method. The characterization of complex compounds was conducted through melting point, SEMEDX and FTIR instrumentation, electrical conductivity, and cyclic voltammetry. The complex of K3[Fe(SCN)6] has melting point 92-95 °C, electrical conductivity f 714 S, and indicated an ionic compound. The characterization with SEM-EDX and FT-IR instruments showed the empirical formula of complex compounds was KCu[Fe(SCN)6]. The cyclic voltammetry analysis shows the complex as potassium-ion battery cathode material. © Published under licence by IOP Publishing Ltd.
