Zinc Air Batteries

Researches about renewable rechargeable battery have attracted the attention of many scholars, due to increasing demands of energy and global energy crisis. Zinc-air batteries are one of most promising energy sources, but the morphological changes and forming dendritic of zinc anodes greatly limit their cycle life during the charging-discharging process. In order to improve zinc-air batteries electrochemical performance and control dendritic growth, surface of zinc anodes is irradiated by femtosecond laser with different power. The electrochemical results indicate that zinc anodes of zinc-air batteries with different surface structures show different electrochemical properties. Due to the removing oxide layer on the surface of zinc anode, adding contact areas of zinc anodes and electrolytes, and restraining dendritic growth by femtosecond laser processing, first discharge time of zinc anodes with surface structures of zinc-air batteries is about 10 times than that of without processing. It is also found that more intense chemical reactions occur in the area treated by femtosecond laser.
