A team at the University of Manchester (UK) has developed a doped graphene cathode for highly stable lithium-sulfur batteries. This technique is a one-step fabrication process without a binder to form a current collector for lithium sulfur battery cathodes. C, 1 C, 2 C and 3 C charge rates. —Huang et al.

(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.
