Lithium Sulfur

Sulfurized carbon nanotubes (SCNT) with a high sulfur content (68%) have been produced with a unique method. Li–S cells comprised of the developed SCNT cathodes presented a long cycle life exceeding 1300 cycles and an extremely low capacity decay rate (0.025% per cycle) at 1/3 C rate. Moreover, their Coulombic efficiency was higher than 95.5%.
