Popis: | The fabrication and design of electrodes that transfer more energy at high rates is very crucial for battery technology because of the increasing need for electrical energy storage. Usually, reducing a material’s volume expansion and improving its electrical conductivity can promote electron and Li+/Na+ ion transfer in nanostructured electrodes and improve rate capability and stability. Here, we demonstrate a general metal–Aspergillus niger bioleaching approach for preparing novel fungus-inspired electrode materials that may enable high-performance lithium ion/sodium ion batteries with one-dimensional architectures. The fungus functions as a natural template to provide large amounts of nitrogen/carbon sources, which are functionalized with metal sulfide nanoparticles, yielding various metal sulfide nanoparticles/nitrogen-doped carbonaceous fibers (MS/NCF (MS = ZnS, Co9S8, FeS, Cu1.81S)) with high conductivity. In addition, the as-obtained MS/NCF has a uniform fiber architecture and abundant porous structu... |
