Abstract

A facile ball-milling route, which can help in large-scale synthesis, is developed to prepare graphene-wrapped sulfur/carbon nanotubes composite. Electrochemical tests show that the obtained composite demonstrates high sulfur utilization and good cycle performance. As calculated by the total mass of the composite, a high reversible capacity of 626.0 mA h g^-1 can be obtained after 70 cycles at a current density of 400 mA g^-1.
