The cells also exhibited an ultralong cycle life exceeding 2000 cycles and an extremely low capacity-decay rate (0.028% per cycle)—among the best performance demonstrated so far for Li/S cells, according to the researchers. The achieved best performance for earlier nitrogen-doped graphene-S nanocomposites was about 671 mA h g ?
