(211f) Laser-Synthesized Zn/Co-Based Metal-Organic Frameworks Composited with Reduced Graphene Oxide As High-Performance All-Printed Energy Storage Devices

Supercapacitors (SCs) with rapid recharge rates and substantial power output bridge the gap between conventional capacitors and batteries, making them essential components in energy storage applications. Metal-organic frameworks (MOFs) have emerged as promising candidates for SC technology due to their unique properties, including high porosity, tunable pore size distribution, and exceptional structural adaptability. When composited with other materials, such as carbon-based compounds, graphene, and graphene oxide, to produce hybrid nanocomposites (HNCs), they achieve high conductivity and enhanced chemical stability, making them ideal as high-performance electrode materials in SCs. This study presents a rapid and cost-effective method for synthesizing bimetallic MOFs composited with reduced graphene oxide (rGO) for energy storage applications. Our results demonstrate that Laser-derived bi-MOF-rGO HNCs exhibit high specific capacitance and power density, showcasing their potential for SC technology. Furthermore, we successfully integrate these HNCs into an all-printed active electrode material layer using sequential inkjet printing, offering a pathway for developing high-performance printed electronics.
