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.

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. Furthermore, the S@NG cathode can be cycled with an excellent Coulombic efficiency of above 97% after 2000 cycles.

Researchers from Tsinghua University have developed what they call a “promising strategy” to tackle the intrinsic problems of lithium metal anodes for Lithium sulfur batteries—dendritic and mossy metal depositing on the anode during repeated cycles leading to serious safety concerns and low Coulombic efficiency.
