Abstract
Prussian Blue Like (PBL) complex compounds have been synthesized and studied as K-Ion Battery (KIB) electrodes. KIB can be developed as an alternative battery because its advantages are more cheaper and secure in comparison with L-Ion Battery (LIB). In this research, the complex compound of K2[Zn(Q)2][Co(SCN)6] was synthesized from K4[Co(SCN)6], Zinc(II) Chloride and Quinoline using a direct reaction method. Synthesized complex compounds was characterized through melting point, SEM-EDX, FT-IR, electrical conductivity,UV-Vis and cyclic voltammetry. The PBL complex has melting point 179-181degree C, electrical conductifity 468 microsiemens, and indicated an ionic compound. Characterization using FT-IR showed the pbl complex has a functional groups of thiocyanate and quinoline. The UV-Vis spectrum of K4[Co(SCN)6] and PBL complex shows absorption peaks at 619.5 and 519 nm. The PBL complex can be oxidized on 0.34 V.
