Better cathode materials for lithium-sulphur-batteries

Researchers have for the first time fabricated a nanomaterial made from nanoparticles of a titanium oxide compound that is characterized by an extremely large surface area, and tested it as a cathode material in lithium-sulphur batteries. The highly porous nanomaterial possesses high storage capacity that remains nearly constant over many charging cycles.
