| Abstract Scope |
In this talk we explore the optimization of Al-air batteries through nanoscale design of microstructure, property control and device manufacturing. We specially introduce a three-dimensional (3D) Al7075 anode processing with femtosecond laser and friction-stir processing (FSP) and integrate 2D nanomaterials with nanowire for oxygen reduction catalysis. Friction-stir processing reduced the mean grain size from 30 μm to 3 μm. While laser cutting enables 3D structures, non-thermal inaction leads to grain refinement at a nanoscale. MnOOH nanowires supported by MXene displayed enhanced catalysis. In a double-face flowing Al-air battery system, the 3D Al7075 FSP anode exhibited significantly better electrocatalytic performance (discharge voltage of 0.76 V at 400 mA cm-2, and power density of 338 mW cm-2) than that of a commercial Al 7075 anode. |
