Abstract
The invention relates to the technical field of preparation of electrochemical cell electrode materials, and provides a carbon-coated polysulfide heterojunction material, which is composed of a core body and a shell body coating the outer side of the core body, wherein the core body is a polysulfide heterojunction and the shell body is a carbon layer. The polysulfide heterojunction is a mixture oftwo or more transition metal sulfides. The method for preparing the polysulfide heterojunction material is easy to operate, low in processing cost, good in treatment effect, wide in application range, recyclable and friendly to environment. The material is coated with carbon and is used as an electrochemical cell electrode material to solve the technical problem of low ion and electron transmission speed in the electrode material in the prior art, thereby achieving a high reversible capacity and good rate performance.
