Reducing pore tortuosity in electrodes of lithium (Li)-ion batteries through directional alignment of the pore structure can minimize the path for ion transportation and facilitate the process. In addition, mechanical properties of electrodes are vital to withstanding mechanical stresses that originate during battery assembly and charging/discharging cycles. The ice-templating technique enables the synthesis of ceramic materials with directional porosity and has drawn significant attention for the fabrication of porous electrodes for Li-ion batteries. However, very little progress has been made on the fabrication of these electrodes using ice-templating technique. In this presentation, we will address the influence of various intrinsic parameters on microstructure development in ice-templated sintered porous metal oxides and compressive mechanical properties. It will be discussed that for a targeted porosity, intrinsic parameters can have remarkable influence on the templated microstructure and compressive mechanical properties. Few results on the electrochemical performance will also be presented.
