A thin sheet of graphene wrapped around a new multifunctional sulfur electrode that combines an energy storage unit and electron/ion transfer networks could lead to a promising design for rechargeable lithium-sulfur batteries. Lithium-sulfur batteries are of great commercial interest because they boast theoretical specific energy densities considerably greater than those of their already-well-established cousin, lithium ion batteries. And we clearly need battery improvements, there hasn't been anything substantial for 25 years. read more
