Abstract
Sn4+xP3 @ amorphous Sn-P composites are a promising cheap anode material for sodium-ion batteries with high capacity (502 mA h g−1 at a current density of 100 mA g−1), long cycling stability (92.6% capacity retention up to 100 cycles), and high rate capability (165 mA h g−1 at the 10C rate).Keywords
