| titleOfInvention | Preparation method and application of high-performance porous lithium-sulfur battery positive electrode material based on carbon/oxygen-rich functional groups |
| abstract | The invention utilizes the reaction between compounds containing carbon/oxygen functional groups (such as compounds containing hydroxyl and carbonyl) to further carbonize the reaction product at high temperature, so as to synthesize a polar material rich in the carbon/oxygen functional groups and a unique porous structure, and further prepare a high-performance porous lithium-sulfur battery cathode material. The special porous carbon material rich in carbon/oxygen functional groups greatly improves the chemical adsorption effect of the host material on polysulfide, reduces the loss of polysulfide, provides a huge specific surface and increases reaction site active sites, thereby reducing electrochemical polarization, improving the reaction rate, and improving the energy density, the power density and the cycle life of the electrode material to a great extent. The invention uses the domestic raw materials with low price, is environment-friendly and has simple and convenient method. The material prepared by the invention can be widely used for preparing high-performance lithium ion and sodium ion batteries and other energy conversion and storage devices such as lithium/sodium-sulfur batteries, metal air batteries and the like. |
