Synergistically engineered flexible/free-standing metals oxide and mixed metal oxides nanoclusters with reversible Na+ storage and enhanced initial coulombic efficiency

Structure Engineering of WS2@Carbon Nanofibers for CO2 Capture, Supercapacitors, and Na-Ion Storage

“…Pure CNF is brittle and has limited ionic conductivity and electrolyte affinity, requiring the inclusion of metallic crystallites to scatter applied stresses and avoid crack formation, as well as conductive additives to modify ionic conductivity and electrolyte absorption capacity due to its 1 T /2H heterophase structure (Figure S1). , It is obvious that both phases are more feasible for energy storage devices after modification. We would therefore like to develop an effective strategy that can not only prepare the high-ratio metallic phase of TMDC nanomaterials but also prevent the metallic phase transformation to the 2H phase .…”

“…8−11 Moreover, CNF have been the focus of worldwide research due to their inter-and intrafiber conductivity as well as their great flexibility for free-standing electrodes. 12 In addition, the electrospinning technology for producing flexible CNF and the ability to customize their graphite layer growth direction are major aspects that encourage researchers to examine the full potential of CNF in the energy storage device industry. Flexible CNF, when paired with TMDC nanosheets, would provide low diffusion distances for rapid ion transport and robust structural integrity to effectively buffer the loss of mechanical strength during charge/discharge cycles.…”

“…Carbonaceous materials, such as mesoporous carbons, carbon nanotubes, MXene, or graphene, and carbon nanofibers (CNF) offer lower cost and energy for cyclic regeneration, readily tunable pore structure, and surface functionalization for CO 2 capture. − Moreover, CNF have been the focus of worldwide research due to their inter- and intrafiber conductivity as well as their great flexibility for free-standing electrodes .
