Abstract:
Metallic lithium embodies a large amount of energy. In order to improve sustainable use of this reactive element, it is crucial to harness this energy effectively. A lithium/sulfur (Li/S) battery has been regarded as one of the candidates for next generation battery because of high theoretical capacity at 1672 mAh per g, low cost of the materials, and environmentally benign nature of elemental sulfur. By using novel 3-D scaffolds based on nano-structured carbon infiltrated with sulfur, great improvements in energy density and cycle life have been demonstrated. Novel Concepts for scaffold to scaffold recovery from spent batteries for enhancing sustainability is discussed.
