The　most　challenging　issue　in　flexible/portable　energy　storage　devices,　such　as　metal-air　batteries,　is　the　insufficient　electrocatalytic　performance　of　the　air-electrode　for　oxygen　reduction/evolution　reactions　due　to　low　activity　and　decomposition　of　the　electrocatalyst　from　the　electrode＇s　surface.　In　an　effort　to　overcome　these　barriers,　robust　and　highly　active　FeNi@NCNTs　nanowire　arrays　are　rationally　synthesized　on　carbon　cloth　which　directly　serves　as　an　integrated　air-electrode　for　zinc-air　batteries.　FeNi@NCNTs/CC　shows　excellent　bifunctional　electrochemical　performances　toward　oxygen　reduction　reaction　(onset　potential　=　0.95　V,　half-wave　potential　=　0.77　V　vs　RHE)　and　oxygen　evolution　reaction　(eta　=　252　mV@10　mA　cm(-2)),　and　exhibits　excellent　stability　after　being　tested　for　more　than　720　hours.　More　importantly,　flexible　solid-state　rechargeable　Zn-air　batteries　directly　equipped　with　the　FeNi@NCNTs/CC　air-cathode　are　demonstrated　to　exhibit　a　high　discharge　voltage　(approximate　to　1.0　V@2　mA　cm(-2))　and　a　low　charge　voltage　(approximate　to　1.65　V@2　mA　cm(-2)),　along　with　an　excellent　mechanical　and　cycling　stability　(voltage　gap　increased　approximate　to　0.03　V　after　200　cycles).　The　novel　designed　air-cathode　and　simple　methodology　for　flexible　solid-state　rechargeable　Zn-air　batteries　contribute　valuable　enlightenment　toward　the　development　of　emerging　portable　electronics　in　practice.
