2000 Design Lithium Sulfur Low Cost 
Green Car Congress
JUNE 7, 2020
Scientists from the Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a novel silica-based cathode for lithium–sulfur batteries, thereby enabling the realization of batteries that can last for more than 2,000 charge/discharge cycles. Silica, a low-cost metal oxide, is actually non-conducting.

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 ?
