Carbon nanotube / sulfur nanocomposites for lithium-sulfur batteries

摘要

Lithium-sulfur batteries potentially offer very high specific energies and are therefore candidates for future generation energy storage in various mobile applications. However, multiple challenges regarding the material design of different cell components need to be overcome. Among them, the low conductivity of sulfur requires the design of new carbon materials for contacting and stabilizing the active component. Here, we introduce vertical aligned carbon nanotube / sulfur nanocomposite electrodes as cathodes with very high capacity.
