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. However, using sulfur in batteries is tricky for two reasons.

Researchers in China, with colleagues from Lawrence Berkeley National Laboratory, have synthesized an additive-free nanocomposite cathode in which sulfur nanoparticles are wrapped inside nitrogen-doped graphene sheets (S@NG). Furthermore, the S@NG cathode can be cycled with an excellent Coulombic efficiency of above 97% after 2000 cycles.
