Abstract: Hollow NiO microspheres with porous shell are synthesized through the ion exchange of a facile zinc citrate template with the subsequent chemical etching. As an anode material for LIBs, the porous hollow NiO electrode shows much higher reversible capacity and better cycling stability in comparison with the ZnO-NiO composite. After 400cycles under a high current rate of 1C, the discharge capacity of the NiO electrode is steadily maintained around 700mAg-1. This excellent high power performance is attributed to the unique hollow and porous nanostructure, which not only increases the speed of mass transport but also accommodates the drastic volume change during the cycling process.
