Nitrogen-doped Graphene Hollow Microspheres as an Efficient Electrode Material for Lithium Ion Batteries

Nitrogen-doped graphene hollow microspheres (NGHSs) have been employed as the anode material for LIBs, and exhibit significantly high rate capacity, good reversibility, and excellent cycling stability, which clearly demonstrate the potential uses of the NGHSs to boost both energy and power densities of LIBs.
