Hetero-CoP/FeP nanoparticles embedded in porous carbon nanofibers were used as the anode for sodium-ion batteries, exhibiting fast Na+ kinetics and excellent cycling stability.
Cubic-shaped WS2 nanopetals/flowers on nitrogen-doped nanoporous carbons, with excellent rate capability and cycling stability of sodium-ion batteries, were developed from Prussian blue nanocubes via solvothermal methods.
A graphene/N-doped porous carbon nanofiber (RGO/NPC) composite was designed as an anode material for sodium-ion batteries (SIBs). A microstructure of fine and uniform N-doped porous carbon nanofibers decorated on 2D RGO sheets was obtained.
SnS/C nanocomposites were simply prepared as anode materials for sodium-ion batteries. They showed excellent cycling stability at various current densities with more than 90% of its capacity delivered when the current increased from 50 to 500 mA g−1.
TiO2−x@NC with plenty of oxygen vacancies and surface nitrogen-doped carbon coating has been prepared and exhibits excellent cycling stability and superior rate capabilities as an anode material for SIBs.
