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.

Long-term cycling performance test of the S@NG electrode at 2 C discharge/charge rate. 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).

Numbers in parentheses are the specific energy of a battery made of the cathode and a silicon anode with a specific capacity of 2000 mAh/g and potential of 0.45 1 V at the beginning of the first charging of Li 2 S. Subsequent cycling showed that the material behaves similar to common sulfur cathodes with high energy efficiency.
