A multifunctional bridged-carbon scaffold: a universal electrodeposition platform for bifunctional catalysts toward flexible zinc–air batteries
A universal ORR-integrated substrate strategy enables electrodeposition of diverse OER catalysts (<i>e.g.</i>, NiFe-LDH, Co(OH)<sub>2</sub>, FeS-Fe<sub>3</sub>O<sub>4</sub>) on cotton-derived N,S-doped cotton carbon cloth (NS-CCC) as bifunctional self-supporting electrodes. NS-CCC provides intrinsic ORR activity and conductive 3D scaffolds, while interfacial M-O/N-C bonds enhance catalyst anchoring. NiFe-LDH/NS-CC achieves 380 mV OER overpotential at 100 mA cm<sup>-2</sup> and 0.78 V ORR half-wave potential, empowering stable flexible Zn-air batteries for more than 700 cycles.
