| titleOfInvention | Preparation method of three-dimensional porous carbon aerogel material and application of three-dimensional porous carbon aerogel material in lithium-sulfur battery |
| abstract | The invention belongs to the technical field of lithium-sulfur batteries, and particularly relates to a preparation method of a three-dimensional porous carbon aerogel material, which comprises the following steps: (1) adding melamine and triethanolamine into a formaldehyde aqueous solution to prepare a melamine-formaldehyde prepolymer; (2) adding lignin into water, firstly adjusting the pH value to fully dissolve the lignin, and then adjusting the pH value to separate out the lignin in the form of nano particles; (3) uniformly mixing hydrophilic silicon dioxide with the solution obtained in the first two steps; (4) slowly adding toluene into the solution obtained in the step (3) to obtain emulsion, polymerizing the emulsion into hard gel, and soaking the hard gel in ethanol to replace the internal phase; (5) sintering at high temperature, etching off silicon dioxide with hydrofluoric acid, and drying. The method has the advantages of simple process and low production cost, the prepared carbon aerogel material has a three-dimensional network and a hierarchical pore structure, and the carbon aerogel material can realize sulfur fixation and catalysis when being applied to the lithium-sulfur battery anode, realize high sulfur load, greatly improve the cycle stability, the rate capability and the coulombic efficiency of the lithium-sulfur battery anode and has higher practical application value. |
