Three-dimensional Honeycomb MoP@C Nanocomposite with Advanced Sodium/Potassium Ion Storage Performance
Graphical Abstract: Three-dimensional honeycomb MoP@C composites were prepared and used as anodes for sodium-ion batteries and potassium-ion batteries. 3D MoP@C shows high reversible capacity and cycle stability (250 mAh g−1 at 0.5 A g−1 after 100 cycles for sodium-ion batteries and 147.2 mAh g−1 at a high current density of 1 A g−1 for potassium-ion batteries because honeycomb structure can alleviate the volume expansion of MoP and provide excellent conductivity.
