Effect of cerium dioxide on the anode performance of aluminum-air batteries

In this word, the effects of adding different contents of CeO₂ to pure Al anode alloy plates on the anode performance of aluminum air batteries were evaluated using an electrochemical workstation, a blue dot test system, and scanning electron microscopy (SEM). The results showed that the addition of CeO₂ had a positive effect on the discharge performance of aluminum anodes for aluminum-air batteries, especially at high current density of 100 mA·cm⁻² for Al-0.20 wt% CeO₂ and Al-0.25 wt% CeO₂ anodes, and also improved the electrochemical activity, corrosion resistance, and anode utilization of aluminum anodes.
