Sulfur- layered porous carbon nanostructured matrix - Co3O4 composites: An enhancement of cycling performance in sodium-sulfur battery

For future applications in electric vehicles, power tools, portable devices, and other areas, developing effective cathode materials for sodium-sulfur batteries is crucial. Sulfur is a promising low-cost cathode material due to its high energy density, environmental friendliness, and natural abundance. Sodium-sulfur batteries, with a theoretical capacity of 1672 mAh g-1, offer a higher capacity compared to conventional sodium-ion batteries. However, their use has been limited by the dissolution of intermediate polysulfides, which can impact performance.
