Positive electrode active material and preparation method thereof, positive electrode material, positive electrode, and lithium-sulfur battery |
| abstract |
A positive active material, comprising graphene, a metal sulfide catalyst doped with a heterogeneous metal element supported on the graphene, and elemental sulfur, the elemental sulfur being supported on the graphene and the heterogeneous metal Element-doped metal sulfide catalysts. The invention also provides a preparation method of a positive electrode active material, a positive electrode material, a positive electrode, and a lithium-sulfur battery. The lithium-sulfur battery using the positive electrode active material provided by the present invention has longer cycle life and stronger cycle performance. |
