Synthesis and Characterization of Complex from K₄[Co(SCN)₆], Zinc(II) Chloride and Quinoline as Electrode Material of K-Ion Battery

Abstract:

Prussian Blue Like (PBL) compounds that are potentially used as K-Ion Battery (KIB) electrodes have been synthesized from zinc(II) chloride and quinoline (Qn) precursors combining melting and direct reaction method. The formed K₂[Zn(Qn)₂][Co(SCN)₆] compounds melt in range 179-181°C with conductivity value reaches 468 μS/cm. Thiocyanate and quinoline ligands were characterized using FT-IR and UV-Vis spectrometry. The cyclic voltammetry of the formed compounds showed the reduction potential up to -0.34 V (versus AgCl/Ag).
