A binder-free sulfur/carbon composite electrode prepared by a sulfur sublimation method for Li–S batteries†
Abstract
A binder-free sulfur/carbon composite electrode was prepared by a sulfur sublimation method. Sulfur nanoparticles fill large pores in a carbon paper substrate and primarily have a monoclinic crystal structure. The composite electrode shows a long cycle life of over 200 cycles with good rate performance in Li–S batteries.
