Nitrogen and phosphorus co-doped porous carbons for high energy density and low shuttling Na/S batteries.

Porous carbons with their abundant availability and high electrical conductivity present significant potential as cathode materials for Na-S batteries. In this study, we report the synthesis of nitrogen and phosphorus co-doped porous carbon (P-N co-doped PC) through a one-step carbonization process utilizing ammonium polyphosphate as the source of nitrogen and phosphorus. The average reversible capacities for P-N co-doped PC were 920, 861, 823 and 756 mA h g at current densities of 0.
