| titleOfInvention | A kind of bimetallic sulfide lithium-air battery cathode material and preparation method and application thereof |
| abstract | The invention provides a bimetallic sulfide lithium-air battery positive electrode material and a preparation method and application thereof; the invention first prepares carbon black modified carbon paper, and then uses a co-precipitation method to in-situ grow cobalt zinc on the surface of the carbon black modified carbon paper Bimetallic MOF nanosheet arrays, and finally, hollow zinc-cobalt bimetallic sulfide nanosheet arrays were prepared by low temperature hydrothermal method using thioacetamide as the sulfur source. The positive electrode material obtained by the invention has a hollow and three-dimensional porous structure, more exposure of trivalent cobalt ions, a partial crystalline structure, and can adjust the adsorption energy of the discharge intermediate product LiO 2 , and induce the formation of a disc-shaped discharge product composed of a cross-linked sheet-like structure. Li 2 O 2 , etc., the above-mentioned comprehensive effects make the obtained material of the present invention show excellent electrochemical performance when used in the positive electrode of lithium-air battery, effectively suppress side reactions, and greatly reduce by-products (lithium carbonate, lithium carboxylate, etc.) generation, reduced overpotentials, and improved electrochemical properties such as capacity and battery cycle life. |
