a) Schematic of FLP–carbon nanotube (CNT) matrix used as host for lithium polysulfide catholyte. b) SEM of FLP–CNT. c) Galvanostatic charge–discharge voltage profiles of the first cycle at 0.2 C. d) Cycling stability and CE. The inset shows the utilization of sulfur at a current density of 1 C (calculated based on the maximum capacity during cycling; the theoretical capacity is 1675 mA h g⁻¹).
