Abstract Scope |
High performance Al-air batteries are attractive to replace Li-ion batteries with reducing cost and enhanced safety. In this work, we developed nanostructured Al anodes using femtosecond laser processing. We study different micro-to-nano structures to regulate the ion transporting, manage thermal dissipation during large C-rates for discharging and charging, and suppress the dendrite formation during recharging. The significant improvement of C rates is evidenced. Point-like holes, lines and grid network are compared and the optimized ratio of pore and the activated volume is probing. The roles of nanostructures and grain size are also elucidated. Our study is paving the way to apply Al-air batteries for driving drones. |
