ABSTRACT
Searching for a suitable electrolyte in lithium-ion battery is a challenging task. The electrolyte must not only be chemically and mechanically stable but should also be safe, fabricated using a sustainable approach and able to transport lithium ions efficiently. Metal-organic framework (MOF) is a suitable candidate material that has three-dimensional (3D) crystalline compound which is made from organic ligands as linkers and metal clusters. The cross-linkage between organic ligands and metals creates a network of coordination polymer which contains adjustable voids with high total surface area. Functionalization of MOF could further enhance the properties of MOF, which includes organic linker modification and guest molecule incorporation. In this study, zirconium and iron-based MOFs were synthesized and functionalized with amine and imidazole to tune its physical properties. X-ray diffraction revealed high crystallinity when MOF was loaded with guest molecule. The morphology of MOFs was characterized and it was found that the 3D framework of MOF was not disintegrated upon modification. Smooth surface was expected when fabricating this MOF as solid electrolyte. The existence of main functional groups in MOFs also confirms the successful synthesis of these MOFs.
