Beschreibung
Zusammenfassung:	An immobilized chalcogen system or body comprising a mixture of chalcogen, where at least 17 wt% of the chalcogen is sulfur. The system further includes a carbon with a carbon skeleton that comprises an aromatic conjugated π-bonding system. The activation energy for a chalcogen particle to escape the immobilized chalcogen system or body is ≥ 96 kJ/mole. Preferably the activation energy is ≥ 99 kJ/mole. More preferably the activation energy is ≥ 102 kJ/mole. Most preferably the activation energy ranges from 137.3 kJ/mole to 144.9 kJ/mole. Preferably the immobilized chalcogen system or body may be used as the cathode material of a battery.
