| Popis: | High surface area, biomass-derived carbon has been prepared by means of chemical activation of waste fruit peels with potassium carbonate and investigated as novel sulfur cathode component for lithium-sulfur batteries As evidenced by scanning electron microscopy and nitrogen absorption isotherms, the synthesized material features hierarchical micro-macroporous structure with sponge-like arrangement of interconnected microfilaments. Composite sulfur cathode fabricated with the application of this carbon has been shown to exhibit a very large initial specific discharge capacity of 886 mAh g − 1 at 0.1 C current rate, which remained remarkably stable over subsequent 50 charge/discharge cycles (capacity loss |
