From: Single step transformation of sulphur to Li2S2/Li2S in Li-S batteries
Electrochemical performance of a CSC-S composite cathode using 1.0 M LiPF6 in EC/DMC (1:1 v/v) as electrolyte.
(a) Discharge/charge profiles of CSC-S composite at C/20 (84 mA g−1). (b) Differential capacity plots (DCP) for the 2nd, 3rd and 4th discharge/charge cycle. (c) Cycling performance and Coulombic efficiency at C/5 (335 mA g−1). (d) Rate capability of the cell at various discharge rates. The voltage range is 1 to 3.5 V vs Li+/Li. The capacity values are given related to the sulphur mass. (e,f) Pictures of the separators after 10 and 400 cycles.
