With its historically long popularity in major structural applications, the use of iron has also recently begun to be explored as a functional material. For this purpose, it is more advantageous to use iron as a porous structure, because it can provide higher surface area and reaction rate. This study uses a freeze-casting method, which consists of simple, low-cost processing steps, to produce Fe foam with a mean pore size of 10 μm. We examine the influences of various parameters (i.e., freezing temperature, powder content, and sintering time) on the processing of Fe foam, along with its oxidation kinetics at 550 °C with various heat treatment times. We confirm that Fe2O3 and Fe3O4 oxide layers are successfully formed on the surface of Fe foam. With the Fe oxide layers as an active anode material, the Fe foam can potentially be used as a three dimensional anode current collector for a lithium-ion battery.
