Porous Mg thin films for Mg–air batteries†
Abstract
An alkaline primary Mg–air battery made from a porous Mg thin film displayed superior discharge performances, including a flat discharge plateau, a high open-circuit voltage of 1.41 V and a large discharge capacity of 821 mAh g−1, suggesting that the electrochemical performances of Mg–air batteries can be improved by controlling the Mg anode morphology.
