摘要：
We investigate the effect of Zn addition on an Al-air battery at the anode. The tested Al-air battery consists of a 6 mol% potassium hydroxide (KOH) electrolyte, a fiberglass separator, and a Pt/C + IrO2 cathode. The Zn-added Al(Al60Zn40)-air battery shows a higher power density of 48 mW/cm(2), while a pure Al-air battery exhibits a power density of 38 mW/cm(2). Approximately, 30 charge/discharge cycles of the Al-air battery were performed, while ~ 71 cycles of the Al60Zn40-air battery were performed. Adding Zn to the Al-air battery improves its electrochemical performance and the number of charge/discharge cycles can be significantly increased.
