A team at the University of Manchester (UK) has developed a doped graphene cathode for highly stable lithium-sulfur batteries. In an open access paper in the Nature journal Communications Chemistry , they report 100% charge capacity of Li-S batteries using the cathode material with 500 charge/discharge cycles at 0.5

(b) Capacity retention of sulfur–TiO 2 yolk–shell nanostructures cycled at 0.5 C, in comparison with bare sulfur and sulfur–TiO 2 core–shell nanoparticles. The authors say that, to the best of their knowledge, this is the first time that a lithium–sulfur battery with this level of performance has been described.
