Hierarchical NiCo2O4 spinel nanowire array (H-NCO-NWA) electrocatalysts have been prepared through a facile template-free co-precipitation route. The as-prepared H-NCO-NWA exhibits amesoporous (ca. 8 nm) structure and a high specific surface area of 124 m(2) g(-1). The assembled Li-air batteries presented lower overpotentials, reasonable specific capacity, and enhanced cyclability.
