Zusammenfassung: | The invention discloses a preparation method of a positive electrode material for a solid electrolyte lithium-sulfur battery, relates to a method for preparing a positive electrode material for a lithium-sulfur battery and aims at solving the problems that the compatibility of the positive electrode material for the lithium-sulfur battery and a solid electrolyte is poor and capacity attenuation isfast. The method comprises the following steps of (1) pretreatment of raw materials; (2) mixing of elemental sulfur and a carbon material; (3) grinding of a mixture; (4) preparation of a carbon-sulfur composite material; and (5) preparation of a positive electrode of the solid polymer electrolyte lithium-sulfur battery. The coulombic efficiency of the battery assembled by the positive electrode of the solid polymer electrolyte lithium-sulfur battery prepared through the method can reach over 90%; and the electrode can be applicable to the solid electrolyte lithium-sulfur battery and has considerable specific capacity |
