摘要: This study reports on a facile approach to the fabrication of nanoporous carbon cathodes for lithium sulfur batteries using gyroid replicas based use polystyrene-poly-4-vinylpyridine (PS-P4VP) block copolymers as sacrificial templates. The free-standing network with highly ordered and interconnected porous structure has been fabricated by impregnating precursor solution into copolymer nanotemplates subsequently carbonizing them. A wide range analytical tools have employed characterize material. Prepared nanostructures are envisioned great potential in myriad areas such energy storage/conversion devices owing their fascinating morphology exhibiting high surface area uniform porosity three-dimensional networks. resulting structures infused elemental found work promising electrode demonstrating...
