| titleOfInvention | Self-supporting lithium-sulfur positive electrode material of network polymer containing N, O atoms and preparation method thereof |
| abstract | The invention discloses a self-supporting lithium-sulfur positive electrode material of a reticular polymer containing N, O atoms and a preparation method thereof, wherein the preparation method comprises the following steps: step one, preparing N, O-containing dinitrile monomer; mixing the obtained dinitrile monomer with a catalyst to obtain a mixture; step three, heating the mixture to obtain a polymer; grinding the polymer into powder, and then sequentially carrying out acid washing and water washing to obtain a powder material; and step six, adding the composite material of the reticular polymer and the sulfur and the carbon nano tube into water, and carrying out ultrasonic treatment and filtration to obtain the composite material of the reticular polymer and the sulfur. The lithium-sulfur battery taking the reticulated polymer containing N, O atoms as the positive electrode material has good stability. |
