Abstract Scope |
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. In this presentation, we will address the influence of water-soluble additive sucrose and pH on the fabrication of ice-templated sintered porous metal oxides for Li-ion batteries and mechanical properties. It will be discussed that for a given solid loading of suspensions (i.e., targeted porosity) and freezing front velocity, sucrose and pH have remarkable influence on the templated microstructure and compressive mechanical response. Preliminary results on the electrochemical performance of these materials will also be presented. |
