Li–S batteries have been considered as next generation Li batteries because of their high-theoretical energy density. Over the past few years, researchers have made significant efforts in breaking through critical bottlenecks, which impede the commercialization of Li–S batteries. Beginning with a basic introduction to Li–S systems and their associated mechanism, this review will highlight the application of one specific carbon family, nitrogen-doped carbon materials in sulfur-based cathodes. These materials will include nitrogen-doped porous carbon, carbon nanotubes, nanofibers, and graphene. The article will conclude with a summary of recent research efforts in this field as well as the future prospects for the use of nitrogen-doped carbon materials in Li–S batteries.
