| 520 | _ | _ | |a The increasing demand for renewable energy sources, such as wind and solar, is driving the need for efficient and sustainable energy storage systems. Among the promising alternatives to conventional batteries, iron-air batteries have gained significant attention due to their high energy densities (2,500 WhL-1), intrinsic safety, environmental friendliness, and reliance on abundant materials. However, a key challenge with traditional iron-air batteries is the solid iron electrode, where surface passivation caused by oxidation products limits charge transport and leads to extended formation cycles. Therefore, the development of iron electrodes with a high loading of active material to enhance storage capacity, while ensuring efficient charge transport at practical current densities, is essential to fully unlock the potential of iron-air batteries.This study focuses on the investigation of iron-slurry/air battery designed to combine the advantages of conventional iron-air batteries with the design flexibility of flow batteries, enabling independent control of energy capacity and power output. Iron-coated carbon powder was initially synthesized as an active material, where conductive carbon particles facilitate electron transport. Key parameters such as iron content (to maximize capacity) and slurry viscosity (to ensure efficient flow and pumping) were optimized. The synthesized slurry was then characterized using X-ray diffraction (XRD) for phase identification, while morphological and elemental analyses were conducted using transmission electron microscopy (TEM), scanning electron microscopy (SEM), and inductively coupled plasma-optical emission spectroscopy (ICP-OES). Electrochemical behavior was evaluated through open circuit potential (OCP), cyclic voltammetry (CV), and chronopotentiometry (CP) measurements. Based on these physical and electrochemical characterizations, the optimized slurry formulation was selected and mixed with an alkaline electrolyte (KOH solution) to fabricate the iron slurry electrodes. A proof-of-concept iron-slurry/air battery was demonstrated for the first time, offering clear evidence of the system’s practical viability. This demonstration provides critical insight into the potential of slurry-based battery systems and suggests a viable pathway towards enhanced sustainability and efficiency in renewable energy storage applications. |
