Hollow carbon nanospheres are synthesized via the hydrothermal carbonization of glucose in the presence of nanosized latexes templates. The resulting disordered carbon hollow nanospheres exhibits excellent characteristics in terms of reversible capacities, cycling performance, and rate capability for application as an anode material in Na-based batteries.
