Abstract:
... An advanced cathode material, nitrogen-doped carbon-coated Na₃V₂(PO₄)₃ hybriding with multiwalled carbon nanotubes (CNTs) composite, namely double-nanocarbon synergistically modified Na₃V₂(PO₄)₃ of sodium ion battery, was fabricated through a simple sol–gel approach. According to the systemical analysis of experimental results on this composite structure, it is found that N-doping not only increas ...

Abstract:
... This study proposes a facile method for synthesis of Au-coated magnetic nanoparticles (AuMNPs) core/shell nanocomposites with nanoscale rough surfaces. MnFe₂O₄ nanoparticles (NPs) were first modified with a uniform polyethylenimine layer (2 nm) through self-assembly under sonication. The negatively charged Au seeds were then adsorbed on the surface of the MnFe₂O₄ NPs through electrostatic interact ...

Abstract:
... The practical use of lithium–sulfur batteries for the next-generation energy storage, especially the automobiles, was hindered by low electronic conductivity of sulfur and the resulting poor rate capabilities. Here, we report a sulfur–carbon composite by confining S into a graphene sandwiched in mesoporous carbon nanosheets with a two-dimensional ultrathin morphology, suitable mesopore size and la ...

Abstract:
... In order to get an element substituted into Na₃V₂(PO₄)₃/C in an appointed V site, the simple sol–gel method is used to design and prepare a series of Na-rich Na₃₊ₓV₂–ₓNiₓ(PO₄)₃/C (x = 0–0.07) compounds. To get a charge balance, the ratio of Na, V, and Ni would be changed if Ni goes into a different site. Hence, ICP is applied to probe the real stoichiometry of the as-prepared Na₃₊ₓV₂–ₓNiₓ(PO₄)₃/C ...
