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 w...
