| titleOfInvention | Polypyrrole-coated hollow porous cobalt manganate-loaded sulfur composite material, preparation method thereof, lithium-sulfur battery positive electrode and lithium-sulfur battery |
| abstract | The invention discloses a polypyrrole-coated hollow porous cobalt manganate-loaded sulfur composite material, a preparation method thereof, a lithium sulfur battery anode and a lithium sulfur battery, wherein ZIF-67 and potassium permanganate are dispersed in an aqueous solution, and the obtained cobalt manganate powder has a dodecahedron hollow structure through hydrothermal reaction; the method comprises the steps of preparing a cobalt manganate/sulfur composite material by a sulfur smoking method, then further wrapping a polypyrrole conductive layer on the outer surface of the composite material, improving the cycle stability and the rate capability of the lithium-sulfur battery, enabling the hollow structure to contain more adsorbed sulfur, improving the sulfur loading capacity, enabling the cobalt manganate to have active sites which strongly adsorb polysulfide, effectively slowing down the shuttling effect of the polysulfide between a positive electrode and a negative electrode, meanwhile, enabling an outer layer conductive polymer to enhance the conductivity of the composite material, improving the conductivity of the positive electrode of the lithium-sulfur battery, further slowing down the shuttling effect of the polysulfide between the positive electrode and the negative electrode, and enhancing the cycle stability and the rate capability of the lithium-sulfur battery. |
