A team at Sun Yat-sen University in China has developed new high-performance, stable cathode for Li-S batteries consisting of a 3D activated carbon fiber matrix (ACFC) and sulfur. The structured 3D foldable sulfur cathode (ACFC-S) delivers a reversible capacity of about 979 mAh g −1 at 0.2C; a capacity retention of 98% after 100 cycles; and 0.02% capacity attenuation per cycle.
