3D Interconnected Electrode Materials with Ultrahigh Areal Sulfur Loading for Li–S Batteries

Sulfur electrodes based on a 3D integrated hollow carbon fiber foam (HCFF) are synthesized with high sulfur loadings of 6.2–21.2 mg cm−2. Benefiting from the high electrolyte absorbability of the HCFF and the multiple conductive channels, the obtained electrode demonstrates excellent cycling stability and a high areal capacity of 23.32 mAh cm−2, showing great promise in commercially viable Li–S batteries.
