"store up to two times more energy per kilogram... double the range of electric vehicles without any increase in the weight of the battery pack. Also, sulfur is more abundant and less problematic to source than the cobalt used in traditional lithium-ion battery cathodes... much longer cycling lives than typical lithium-sulfur battery... improve both cathode and anode while providing high conductivity and interfacial stability... more stable by grafting to polymer... prevents more sulfur from dissolving into the electrolyte"
