Polymer electrolyte coated sulfur@carbon fiber composite solid electrode was prepared by the two methods of microscopic and macroscopic coating with polymer electrolyte in the cathode sheet of lithium sulfur battery. The microscopic morphology of the electrode was characterized by scanning electron microscopy, and the corresponding performances of the battery with different cathode structures were also analyzed. Results show that the electrode structure of microscopic polymer solid electrolyte coated active material is favorable for ion transfer. Macroscopically constructing a polymer solid electrolyte film on the electrode surface can improve the cyclic stability of the electrode and inhibit the shuttle effect. The all-solid lithium-sulfur battery assembled with the membrane electrode structure has good cycle performance. After 270 cycles, the Coulomb efficiency still keeps over 98 %.
