| titleOfInvention | Polyamine composite material, slurry, electrode plate, lithium-sulfur battery and preparation method |
| abstract | The invention discloses a polyamine composite material, slurry, an electrode plate, a lithium-sulfur battery and a preparation method thereof. The polyamine composite material comprises a carboxylated carbon-based material at the innermost layer, sulfur at the intermediate layer and polyamine at the outermost layer, wherein part or all of amino groups on the polyamine and part or all of carboxyl groups on the carboxylated carbon-based material are subjected to dehydration condensation to generate bonding. The material can improve the specific discharge capacity of sulfur, adsorb lithium polysulfide and inhibit the falling of sulfur. The invention also provides a preparation method of the material. The invention also discloses slurry which comprises a conductive agent, a binder, a solvent and the polyamine composite material. The invention also discloses an electrode plate, which comprises a current collector and an electrode material layer positioned on the current collector, wherein the electrode material layer is a coating layer formed by the polyamine composite material or a coating layer formed by coating the slurry on the current collector and removing the solvent. |
