(D) Cycle performance and Coulombic efficiency of MPNC-S70 cycled at a current density of 0.35 mA cm−2 for the first two cycles and 0.70 mA cm−2 for the subsequent cycles. The capacity values were calculated based on the mass of sulfur. Reprinted with permission from (Song et al., 2014). Copyright 2014, Wiley-VCH.
