Abstract: The present invention provides a high-performance lithium-containing organic sulfur electrode material and a preparation method of an integrated flexible electrode. According to the present invention, 1,3-diisopropenyl benzene with diene bonds and Li2S6 are used as precursors to react to generate the lithium-containing organic sulfide Poly (Li2S6-r-DIB) through an in-situ polymerization method. The synthesized lithium-containing organic sulfide Poly (Li2S6-r-DIB) can be directly attached to a flexible conductive carbon cloth to prepare the integrated flexible electrode due to its good viscosity when heated to a certain temperature. The obtained flexible electrode has the advantages of high capacity, high flexibility, stable structure and the like.
