Lithium-Sulfur Batteries With High Capacity + Rate Performance Via Vertically Aligned Sulfur-Graphene Nanowall Cathodes
New cathode materials for lithium-sulfur batteries constructed out of vertically aligned sulfur–graphene (S-G) nanowalls on electrically conductive substrates — delivering high capacity + rate performance — have been developed by researchers at Beihang University in China. The new cathode materials allow for the fast diffusion of lithium ions + electrons … [continued]
