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).

The Nobel Prize in Chemistry 2000 was awarded jointly to Alan J. The CAS team sandwiched their PNTF layer between the sulfur cathode and the separator to act as the functional interlayer for the Li–S battery. 2 sulfur loading on the electrode, the initial discharge capacity is 1102 mAh g ?1 Heeger, Alan G. —Ma et al.

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.

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.
