摘要

•Hollow ZnCo2O4 porous microspheres were synthesized based on a template-free method.•This special nanostructure of ZnCo2O4 was first applied as cathode for Li-S battery.•It shows a reversible capacity of 642 mAh g−1 at a very high current density of 10C.•It can keep a discharge capacity at 704 mAh g−1 after 1000 cycles at 2C.
