capacity dramatically decreases at the second cycle, which
suggest that a surface film can be formed effectively during the
first cycle [33]. After 20 cycles, the specific capacity maintains
about 300 mA h g , so the NiO hollow spheres seem a promising
anode materials for lithium-ion batteries in terms of slow capacity
fading rate and high coulombic efficiency.

In summary, this paper describes a simple solvothermal
method that leads to the mesoscale assembly of NiO nanosheets
into spheres. The geometric constraints and surfactant-assistant
growth mechanisms have been used to properly discuss assembly

SBET of NiO is tunable, which implies the feasibility to tune
the surface areas of porous materials by adjusting the quantity
of surfactant.
