Adiabatic and Nonadiabatic Charge Transport in Li–S Batteries [PDF]
Chemistry of Materials, 2018 The insulating nature of the redox end members in Li-S batteries, a-S and Li2S, has the potential to limit the capacity and efficiency of this emerging energy storage system. Nevertheless, the mechanisms responsible for ionic and electronic transport in these materials remain a matter of debate.
