Improving the electrochemical properties of the red P anode in Na-ion batteries via the space confinement of carbon nanopores

Abstract

We develop a strategy to improve the electrochemical properties of red P by controlling the sodiation reaction to form NaxPy intermediates rather than the complete sodiation product of Na3P. The resultant red P@carbon nanocomposite shows a highly stable cyclability (capacity retention > 88% after 200 cycles), excellent rate capability, and high capacity for sodium storage.
