SiO sub(2)-coated sulfur particles with mildly reduced graphene oxide as a cathode material for lithium-sulfur batteries

For the first time, SiO sub(2)-coated sulfur particles (SCSPs) were fabricated viaa 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, maintainin...

Summary:For the first time, SiO sub(2)-coated sulfur particles (SCSPs) were fabricated viaa 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 super(-1) after the 50 super(th) cycle.
