SiO2-coated sulfur particles with mildly reduced graphene oxide as a cathode material for lithium–sulfur batteries

Abstract

For the first time, SiO₂-coated sulfur particles (SCSPs) were fabricated via a facile two-step wet chemical process for application as a novel lithium–sulfur cathode material. With the addition of mildly reduced graphene oxide (mrGO), SCSPs demonstrate even greater cycling stability, maintaining over 700 mA h g⁻¹ after the 50^th cycle.
