Graphene oxide-sulfur (GO-S) nanocomposite cathodes for high-capacity, stable cycling lithium sulfur batteries

Green Car Congress

With a theoretical specific capacity of about 1675 mAh g -1 and a theoretical specific energy of 2600 Wh kg -1 , elemental sulfur (S) is very attractive as a cathode material for high-specific-energy rechargeable lithium batteries. These reduced products can also diffuse back to the cathode during recharging. Earlier post.).
