The Cover Feature illustrates the morphology of the binder‐free electrode (bf‐PPy+Co 3 O 4 @CF) and its reactions in seawater. The binder‐free (bf) air electrode is structured with Co oxide (Co 3 O 4 ) anchored on carbon fiber (CF) tissues with the assistance of polypyrrole‐doped carbon (PPy/C) by using a simple infiltration technique. The bf‐PPy+Co 3 O 4 @CF electrode exhibits excellent bifunctional stability for seawater batteries, presenting a comparable performance to the binder‐included Pt/C+IrO 2 electrode.
