Secondary battery is one of the promising technology to overcome the depletion of fossil fuel as energy source. One of the major issues limiting the substantial use of secondary battery especially in electric vehicles, though, is the safety issue. Research has been actively moving forward on solid electrolytes that can replace the current liquid electrolytes in order to address this issue. In the past, studies have used lithium-ion conductive materials such oxides, sulfides and polymers but still facing limitation in the ion conductivity and lithium transference number for solid electrolyte to be commercialized. Recently, MOF and COF with high crystallinity and high porosity are receiving attention in the field of energy storage devices. Thus, the MOF in COF hybrid structure is utilized in this study with Ionic liquid to achieve a high-performance solid-state battery.
