Summary: A lithium sulfur composite electrode (SCPV) is prepared by in situ permeation of PEDOT:PSS onto the surface of a SC (sulfur and carbon nanotubes) electrode. The SCPV electrode exhibits higher discharge capacities compared to the SC electrode at different rates, attributed to the storage of electrolytes and excellent conductivities of PEDOT:PSS. Moreover, the SCPV cathode shows superior cycling stability due to the in situ fixation of PEDOT:PSS, inhibiting shuttle effect and volume change.
